This conference is being hosted by the University of North Texas (UNT) in Denton, TX, Sandia National Laboratories (SNL) in Albuquerque, NM and Livermore, CA, and Los Alamos National Laboratory (LANL) in Los Alamos, NM. CAARI 2016 is also being supported by several other U.S. National Laboratories, industries and agencies most identified with accelerator technology. The Conference Co-chairs and the Topic Editors worked with the Session Chairs to develop the sessions and speakers. This is the 24th International conference in the biennial series that began in 1968 as a Conference on the Use of Small Accelerators for Teaching and Research by Jerry Duggan, while he was a staff member at Oak Ridge Associated Universities. When Jerry moved to Denton, TX and joined the University of North Texas (UNT), he continued the Conference series in 1974, holding the meeting on the UNT campus. At this time, Jerry invited Lon Morgan to join him as a co-organizer. Lon Morgan brought in the industrial components of CAARI and it became known as the International Conference on the Application of Accelerators in Research and Industry (CAARI). CAARI was held in Denton for 30 years. In 2004, Jerry Duggan asked Floyd “Del” McDaniel and Barney Doyle to be co-organizers of the CAARI Conference Series. In 2004, Barney and Del moved the conference to Fort Worth, Texas, where it was held biennially from 2004-2012. In 2012 Yongqiang Wang and Gary Glass were invited to become co-organizers and the conference was held in San Antonio, TX. For the 2016 Conference, Arlyn Antolak has joined as a co-organizer and the conference has returned to the Renaissance Worthington Hotel in Fort Worth, Texas. The CAARI Conference series is unique in that it brings together researchers from all over the world who use particle accelerators in their research and industrial applications. Each year the Topic Areas are reviewed and updated to reflect current research interests. In addition to this brief Program Book with abstract titles and presenting authors, the program with complete abstracts may be found at www.CAARI.com. We hope that you enjoy the conference and find it intellectually stimulating. In the schedule, we have provided several opportunities to renew friendships and talk science at this meeting: the Welcome Reception Sunday evening, the socials during each poster session Monday and Tuesday, the Conference banquet on Wednesday evening, the 2 O’Clock Band Concert on Thursday evening, and the Closing Ceremony on Friday at noon. If there is anything we can do to make your conference experience and stay in Fort Worth, Texas, more enjoyable, just ask Gary, Del, Yong, Barney, Arlyn, Holly, or Carley. We are very happy you have joined us in Fort Worth and hope you have a memorable time! Financial Support Financial support from sponsors, exhibitors, and advertisers is an essential element of a successful conference. This support enables us to provide support for conference events, students, and other attendees.

XIA LLC High Voltage Engineering Europa B.V. Advertisers Trek, Inc. For Security LINACS & Inspection RadiaBeam Systems offers a suite of linac systems that are ideal for a wide range of applications in security and inspection. Linac-based inspection systems produce high-fluxes of X-rays that penetrate even the densest of materials. Our linacs’ cutting edge performance enables high resolution and contrast sensitivity. Alternating, dual energy pulses allow for displaying different materials in different colors, which is an important feature for identifying objects of interest in cargo (i.e. radiological/nuclear threats or contraband). Linac-based inspection systems address various threats, ranging from the detection of controlled materials, customs inspections, and isotope replacements. CARGO & VEHICLE INSPECTION High-energy accelerators, such as our dual energy S6/9-100/75-X, can be configured into powerful inspection systems that can inspect upwards of one hundred cargo containers or vehicles per hour, making it ideal for key border crossings and special-entry sites. RAIL CARGO INSPECTION The inspection of rail cars is important for securing borders while maintaining dedicated trade thoroughfares. Our Adaptive Railway Cargo Inspection System, ARCIS, is capable of discriminating materials in kilometer-long trains at speeds nearing 45 km/h while other systems only allow for 15 km/h. The ARCIS system is able to discriminate materials into four groups based on the atomic number, and to resolve wires smaller than 2 mm in size, while also detecting radiological/nuclear threats. MOBILE INSPECTION An inspection system mounted onto a class C vehicle allows operators to drive to the potential threat for inspection in temporary locations. Our MXS linac is based on compact X-band linac technology that allows for a small size without sacrificing penetration ability. The dual- energy output allows for differentiation between organic and inorganic materials, contraband inspection, and identification of radiological/nuclear threats. www.radiabeamsystems.com | v: +1 310 822 5845 | f: +1 310 582 1212 | [email protected] 16.10.14 HIGH VOLTAGE POWER SUPPLIES RADIO FREQUENCY SYSTEMS MAGNET POWER SUPPLIES TURN-KEY SYSTEMS LEARN MORE ON WWW.OCEM.EU HIGH VOLTAGE ENGINEERING EUROPA B.V.

IRMS Guide 1st Ed. 2011 Preface A few decades ago, mass spectrometry (by which I mean organic MS) was considered a “black art”. Its complex and highly expensive instruments were maintained and operated by a few dedicated technicians and its output understood by only a few academics. Despite, or because, of this the data produced were amongst the “gold standard” of analytical science. In recent years a revolution occurred and MS became an affordable, easy to use and routine technique in many laboratories. Although many (rightly) applaud this popularisation, as a consequence the “black art” has been replaced by a “black box”: SAMPLES GO IN → → RESULTS COME OUT The user often has little comprehension of what goes on “under the hood” and, when “things go wrong”, the inexperienced operator can be unaware of why (or even that) the results that come out do not reflect the sample that goes in.

  • Stable Isotope Methods in Biological and Ecological Studies of Arthropods
    eea_572.fm Page 3 Tuesday, June 12, 2007 4:17 PM DOI: 10.1111/j.1570-7458.2007.00572.x Blackwell Publishing Ltd MINI REVIEW Stable isotope methods in biological and ecological studies of arthropods CORE Rebecca Hood-Nowotny1* & Bart G. J. Knols1,2 Metadata, citation and similar papers at core.ac.uk Provided by Wageningen University & Research Publications 1International Atomic Energy Agency (IAEA), Agency’s Laboratories Seibersdorf, A-2444 Seibersdorf, Austria, 2Laboratory of Entomology, Wageningen University and Research Centre, P.O. Box 8031, 6700 EH Wageningen, The Netherlands Accepted: 13 February 2007 Key words: marking, labelling, enrichment, natural abundance, resource turnover, 13-carbon, 15-nitrogen, 18-oxygen, deuterium, mass spectrometry Abstract This is an eclectic review and analysis of contemporary and promising stable isotope methodologies to study the biology and ecology of arthropods. It is augmented with literature from other disciplines, indicative of the potential for knowledge transfer. It is demonstrated that stable isotopes can be used to understand fundamental processes in the biology and ecology of arthropods, which range from nutrition and resource allocation to dispersal, food-web structure, predation, etc. It is concluded that falling costs and reduced complexity of isotope analysis, besides the emergence of new analytical methods, are likely to improve access to isotope technology for arthropod studies still further. Stable isotopes pose no environmental threat and do not change the chemistry or biology of the target organism or system. These therefore represent ideal tracers for field and ecophysiological studies, thereby avoiding reductionist experimentation and encouraging more holistic approaches. Con- sidering (i) the ease with which insects and other arthropods can be marked, (ii) minimal impact of the label on their behaviour, physiology, and ecology, and (iii) environmental safety, we advocate more widespread application of stable isotope technology in arthropod studies and present a variety of potential uses.

  • Mass Spectrometer Hardware for Analyzing Stable Isotope Ratios
    Handbook of Stable Isotope Analytical Techniques, Volume-I P.A. de Groot (Editor) © 2004 Elsevier B.V. All rights reserved. CHAPTER 38 Mass Spectrometer Hardware for Analyzing Stable Isotope Ratios Willi A. Brand Max-Planck-Institute for Biogeochemistry, PO Box 100164, 07701 Jena, Germany e-mail: [email protected] Abstract Mass spectrometers and sample preparation techniques for stable isotope ratio measurements, originally developed and used by a small group of scientists, are now used in a wide range of fields. Instruments today are typically acquired from a manu- facturer rather than being custom built in the laboratory, as was once the case. In order to consistently generate measurements of high precision and reliability, an extensive knowledge of instrumental effects and their underlying causes is required. This con- tribution attempts to fill in the gaps that often characterize the instrumental knowl- edge of relative newcomers to the field. 38.1 Introduction Since the invention of mass spectrometry in 1910 by J.J. Thomson in the Cavendish laboratories in Cambridge(‘parabola spectrograph’; Thompson, 1910), this technique has provided a wealth of information about the microscopic world of atoms, mole- cules and ions. One of the first discoveries was the existence of stable isotopes, which were first seen in 1912 in neon (masses 20 and 22, with respective abundances of 91% and 9%; Thomson, 1913). Following this early work, F.W. Aston in the same laboratory set up a new instrument for which he coined the term ‘mass spectrograph’ which he used for checking almost all of the elements for the existence of isotopes.

  • Nuclear and Isotopic Techniques for Marine Pollution Monitoring
    NUCLEAR AND ISOTOPIC TECHNIQUES FOR MARINE POLLUTION MONITORING A. Introduction The greatest natural resource on the Planet, the World Ocean is both the origin of most life forms and the source of survival for hundredsth of millions of people. Pollution of the oceans was an essential problem of the 20 century that was associated with the rapid industrializationst and unplanned occupation of coastal zones It continues to be a concern in the 21 century. The most serious environmental problems encountered in coastal zones are presented by runoff of agricultural nutrients, heavy metals, and persistent organic pollutants, such as pesticides and plastics. Oil spills from ships and tankers continually present a serious threat to birds, marine life and beaches. Also, many pesticides that are banned in most industrialized countries remain in use today, their trans-boundary pathway of dispersion affecting marine ecosystems the world over. In addition to these problems, ocean dumping of radioactive waste has occurred in the past, and might occur again, with authorised discharges of radioactive substances from nuclear facilities into rivers and coastal areas contributing to the contamination of the marine environment. A trans-boundary issue, marine pollution is often caused by inland economic activities, which lead to ecological changes in the marine environment. Examples include the use of chemicals in agriculture, atmospheric emissions from factories and automobiles, sewage discharges into lakes and rivers, and many other phenomena taking place hundreds or thousands of kilometres away from the seashore. Sooner or later, these activities affect the ecology of estuaries, bays, coastal waters, and sometimes entire seas, consequently having an impact on the economy related to maritime activities.

  • Investigating the Origin of Cotton in Yarn Using Multivariate Isotope Profiles
    INVESTIGATING THE ORIGIN OF COTTON IN YARN USING MULTIVARIATE ISOTOPE PROFILES W. Meier-Augenstein1,2, N. N. Daeid3, H. F. Kemp1 1 Stable Isotope Laboratory, The James Hutton Institute, Dundee, UK. 2 Environmental and Forensic Science Research Group, Robert Gordon University, Aberdeen, UK. 3 Centre for Forensic Sciences, Department of Pure and Applied Chemistry, WestCHEM, University of Strathclyde, Glasgow, UK. INTRODUCTION The analysis of cotton fibres can be particularly challenging within a forensic science context where discrimination of one fibre from another is of importance. Normally cotton fibre analysis examines the morphological structure of the recovered material and compares this with that of a known fibre from a particular source of interest. Analysis of the dyes which may have been applied to the cotton fibre can also be undertaken though this can be difficult and unproductive in terms of discriminating one fibre from another. The aim of this work was to explore the potential for Isotope Ratio Mass Spectroscopy (IRMS) to be utilised as an additional tool for cotton fibre analysis in an attempt to reveal further discriminatory information. For this proof-of-concept study we concentrated on un-dyed cotton fibres of known origin in order to expose the potential of the analytical technique. Limited amounts of previous research have reported stable isotope analysis of cotton plants, leaves or cellulose and have investigated natural variation in 2H and 18O isotopic abundance in plant dry matter [1], carbohydrates [2] or the effect of water stress on 2H, 18O and 13C isotopic abundance in cellulose [3]. However, these previous studies have confirmed the feasibility of using the 2H, 18O and 13C isotopic composition of cotton cellulose present in cotton fabrics as a potential discriminatory tool.
