ABSTRACT Progress at LAMPF is the semiannual progress report of the MP Division of the Los Alamos National Laboratory. The report includes brief reports on research done at LAMPF by researchers from other institutions and Los Alamos divisions. Los Alamos National Laboratory Mmm Los Alamos, New Mexico 87545 WSTJBBI/r/ow lyj^mm,* Time to Think about the Future: LAMPF continues to increase its capabilities and productivity. Experimenters are asking ever more sharply defined questions and experiments are becoming increasingly illuminating. The rate of accomplishment is high, but strongly limited by budgets for research and operations. This state of affairs is expected to continue through the rest of this decade. However, now is the time to start giving serious thought to the direction of nuclear physics generally, and LAMPF activities in particular — during the 1990s. The vast world-wide effort on weak interactions is almost guaranteed to open new doors for pur­ suing the study of nuclear as well as subnuclear physics. Quark physics appears to be here to stay. Low-energy pion probes are proving extremely powerful, and high-energy ones hold similar promise, as do kaons and antiprotons, for opening new windows on the atomic nucleus. So what shall we do to assure the nation a high level of accomplish­ ment in nuclear physics next decade and perhaps the one beyond that? A serious effort has commenced to explore the options available to us if we use LAMPF as an injector for a higher energy accelerator. Studies are being pursued, workshops are being held, and attempts are under way to elicit the wishes and enthusiasms of the scientific community, upon whom our nation depends for producing the knowledge and people for coping with all matters nuclear. Your input is urgently re­ quired. Without it, nothing will happen.

  • Testing the Stand-Alone Microbeam at Columbia University G
    Radiation Protection Dosimetry Advance Access published December 21, 2006 Radiation Protection Dosimetry (2006), 1 of 5 doi:10.1093/rpd/ncl454 TESTING THE STAND-ALONE MICROBEAM AT COLUMBIA UNIVERSITY G. GartyÃ, G. J. Ross, A. W. Bigelow, G. Randers-Pehrson and D. J. Brenner Columbia University, Radiological Research Accelerator Facility, 136 S. Broadway, Irvington, NY 10533, USA The stand-alone microbeam at Columbia University presents a novel approach to biological microbeam irradiation studies. Foregoing a conventional accelerator as a source of energetic ions, a small, high-specific-activity, alpha emitter is used. Alpha particles emitted from this source are focused using a compound magnetic lens consisting of 24 permanent magnets arranged in two quadrupole triplets. Using a ‘home made’ 6.5 mCi polonium source, a 1 alpha particle s–1,10lm diameter microbeam can, in principle, be realised. As the alpha source energy is constant, once the microbeam has been set up, no further adjustments are necessary apart from a periodic replacement of the source. The use of permanent magnets eliminates the need for bulky power supplies and cooling systems required by other types of ion lenses and greatly simplifies operation. It also makes the microbeam simple and cheap enough to be realised in any large lab. The Microbeam design as well as first tests of its performance, using an accelerator-based beam are presented here. INTRODUCTION AND OVERALL DESIGN the lenses. In addition to providing a secondary user facility at RARAF, the design is simple and Columbia University’s Radiological Research Accel- inexpensive enough that the SAM can be reproduced erator Facility (RARAF) currently offers its users in any large radiation biology laboratory.

Introduction When I was approached by the editors of Physics in Perspecti6e to prepare an article on New York City for The Physical Tourist section, I was happy to do so. I have been a New Yorker all my life, except for short-term stays elsewhere on sabbatical leaves and other visits. My professional life developed in New York, and I married and raised my family in New York and its environs. Accordingly, writing such an article seemed a natural thing to do. About halfway through its preparation, however, the attack on the World Trade Center took place.

  • Expanding the Question-Answering Potential of Single-Cell Microbeams at RARAF, USA
    J. Radiat. Res., 50: Suppl., A21-A28 (2009) Expanding the Question-answering Potential of Single-cell Microbeams at RARAF, USA Alan BIGELOW1,*, Guy GARTY1, Tomoo FUNAYAMA1,2, Gerhard RANDERS-PEHRSON1, David BRENNER1 and Charles GEARD1 Microbeam/Particle accelerator/Cell irradiation/Radiation biology. Charged-particle microbeams, developed to provide targeted irradiation of individual cells, and then of sub-cellular components, and then of 3-D tissues and now organisms, have been instrumental in chal- lenging and changing long accepted paradigms of radiation action. However the potential of these valuable tools can be enhanced by integrating additional components with the direct ability to measure biological responses in real time, or to manipulate the cell, tissue or organism of interest under conditions where information gained can be optimized. The RARAF microbeam has recently undergone an accelerator upgrade, and been modified to allow for multiple microbeam irradiation laboratories. Researchers with divergent interests have expressed desires for particular modalities to be made available and ongoing developments reflect these desires. The focus of this review is on the design, incorporation and use of mul- tiphoton and other imaging, micro-manipulation and single cell biosensor capabilities at RARAF. Addi- tionally, an update on the status of the other biology oriented microbeams in the Americas is provided. west National Laboratory,4) the Gray Cancer Institute,5,6) and INTRODUCTION Columbia University.7) Since that time, the number

  • Tesla's Connection to Columbia University by Dr. Kenneth L. Corum
    * Tesla’s Connection to Columbia University by Kenneth L. Corum and James F. Corum, Ph.D. “The invention of the wheel was perhaps rather obvious; but the invention of an invisible wheel, made of nothing but a magnetic field, was far from obvious, and that is what we owe to Nikola Tesla.” Professor Reginald Kapp, 1956 INTRODUCTION The Electrical Engineering curriculum at Columbia University, though not the first in the US, is one of the oldest and most respected EE programs in the world. From the beginning, a conscientious effort was made to base it on a foundation of science. It has been guided by the specific philosophy stated by Professor Michael Pupin: “Professor Crocker and I maintained that there is an ‘electrical science’ which is the real soul of electrical engineering.” Arguably the most stunning and significant lecture in modern history was presented one spring evening, more than a century ago, at Columbia University. The wealth of nations turned on its merits. Weighing on the balances would be our vast cities, civilization, and quality of life. But, what was it? . .Whatever it was, its impact has been as momentous for the progress and prosperity of civilization as the invention of the wheel! . It was Tesla’s great discovery and analysis of the rotating magnetic field, and a means for the electrical distribution of energy.1 As a result of the analysis presented in this lecture, the great Falls of Niagara would soon be harnessed for the benefit of mankind and launch civilization into the “Electromagnetic Century”. The Engineering Council for Professional Development (now called ABET) has defined “Engineering” as “that profession which utilizes the resources of the planet for the benefit of mankind”.

This integrated design following applications and demonstrations of selective allows the UV microspot to operate in two modes: (1) as a damage to live single cell targets: DNA damage foci for- stand-alone UV microspot irradiator and (2) as a probe to mation, patterned irradiation, photoactivation, targeting of work in concert with ion-beam irradiation experiments.

A rapid automated biodosimetric system used to assess thousands of individual radiation exposure doses is helpful to curb mass panic, and to conserve limited medical resources. This paper presents the development of a new robotically-based automated biodosimetry tool (RABiT). The RABiT is capable of automating two mature biodosimetry assays: the micronucleus and γ-H2AX assay. The design considerations guiding the hardware and software architecture are presented with focus on ease of implementation, methods of communication and need for real-time control versus soft time control cycles.
