While SORMA had traditionally been held every four years, it has been only two years since the previous Sym- posium was held at the University of California. This increased frequency has largely been due to the step change in the world following the attacks on the U.S. World Trade Center, and the emergence of new international threats demanding our community's attention. Radiation detection and measurement science has always been an active field because of the large number of applications that depend upon our measurements, but the new emphasis on security has added demands on our technologies that were unimaginable more than a decade ago. The program that you are about to experience is the culmination of dedicated work of a few hardy vol- unteers. The Organizing Committee has been passionate about ensuring this forum remains open and accessible to all practitioners who are dedicated to our craft. Please join us in gratefully acknowledging the generosity of our Symposium Sponsors who understand the importance of our science and the value of this Symposium. Our exhibitors also would like to invite you to peruse their newest technologies and measurement tools. We have expanded into new spaces to accommodate all of the exhibitors who wished to attend SORMA. We tried to keep the cozy atmosphere while still placing the priority on the scientific program. The technical program before you is scientifically strong and shows remarkable innovations in critical technology areas, including semiconductors, scintillators, gas-filled detectors, ultra-high resolution devices, electronics, and the concepts that exploit them. The Program Committee has carefully selected these technical papers, split approximately evenly between poster and oral presentations, which span the rich spectrum of our field. The presentation format, oral or poster, was determined solely on the most impactful format to showcase the results. SORMA has always favored poster sessions as the predominant presentation method because of the longer exposure time, personal interaction, and warm hospitality. The presentation format is uncorrelated with assessed relevance, importance, novelty, maturity, or quality. If you want to re- ceive the full benefit from this conference, we encourage you to fully immerse yourself in the poster sessions. For your social program, we have chosen activities that will follow the successful programs of the past symposia. Please join us as we stroll to the reception Tuesday night at the University of Michigan Museum of Art. Once there, you will be treated with delectable hors d'oeuvres while being guided through the museum's fine exhibits. Our traditional dinner will return Wednesday night to the famous Henry Ford Museum in Dearborn. We have asked that the gift shop remain open for those wishing to bring souvenirs home. On Thursday night, for those of you staying overnight for the MCNPX-Polimi workshop, there are many other sites worth seeing: watching the Detroit Tigers play a professional baseball game under the stars (the Twins are in town this week), taking in wild night life in Windsor, Canada, or even a scenic canoe trip down our local Huron River. We hope you will take full advantage of Michigan hospitality while you are with us. In closing, we welcome you to this wonderful opportunity to interact with superb colleagues and dear friends. Our community is linked by common interests and pursuits, and you will undoubtedly find the technical presentations by your colleagues to be stimulating and rewarding. Welcome! David. 2 Contents 1 Exhibitors 5 2 Social Programs 7 3 Instructions for Presenters 8 4 Bus Schedule 10 5 Program View of Papers 13 6 Abstracts 22 6.1 Plenary Abstracts . 22 6.2 Tuesday Afternoon . 25 6.2.1 Scintillation Detectors I (Tuesday 1:30 - 3:00 pm in Mendelssohn with David Wehe) 25 6.2.2 Particle/Photon Cancer Therapy, and Other Medical Imaging Applications (Tuesday 1:30 - 3:00 pm in Hussey with Ling-Jian Meng) . 26 6.2.3 Poster I - New Radiation Detectors (Tuesday 3:00 - 4:00 pm in Ballroom with Mark Hammig) . 28 6.2.4 Semiconductor Detectors I (Tuesday 4:00 - 5:30 pm in Mendelssohn with Alan Janos) 45 6.2.5 Neutron Facility, Characterization, Detectors and Generators (Tuesday 4:00 - 5:30 pm in Hussey with Mark Wrobel) . 47 6.3 Wednesday . 49 6.3.1 Neutron Detectors II (Wednesday 8:00 - 9:30 am in Mendelssohn with Donny Horn- back) ........................................... 49 6.3.2 PET, SPECT and Other Medical Imaging Techniques (Wednesday 8:00 - 9:30 am in Hussey with Kanai Shah) . 51 6.3.3 Poster II - Radiation Measurement Techniques (Wednesday 9:30 - 10:30 am in Ball- room with Shaun Clarke) . 53 6.3.4 Room-Temperature Semiconductor Detectors (Wednesday 10:30 - 12:00 pm in Mendelssohn with Mac Black) . 69 6.3.5 Algorithms and Modeling (Wednesday 10:30 - 12:00 pm in Hussey with Sara Pozzi) 71 6.3.6 Inorganic Scintillation Detectors (Wednesday 1:30 - 3:00 pm in Mendelssohn with Igor Jovanovic) . 72 6.3.7 Gamma-Ray Imaging Systems (Wednesday 1:30 - 3:00 pm in Hussey with Kai Vetter) 74 6.3.8 Poster III - Medical and Environmental Applications (Wednesday 3:00 - 4:00 pm in Ballroom with Patricia Schuster) . 76 6.3.9 Nonproliferation, Safeguards, and Homeland Security (Wednesday 4:00 - 5:30 pm in Mendelssohn with Sara Pozzi) . 89 6.3.10 Detector Electronics and Signal Processing (Wednesday 4:00 - 5:30 pm in Hussey with Gianluigi De Geronimo) . 91 6.4 Thursday . 93 6.4.1 Nonproliferation, National and Homeland Security Applications (Thursday 8:00 - 9:30 am in Mendelssohn with Zhong He) . 93 6.4.2 Unconventional Radiation Detectors and Techniques (Thursday 8:00 - 9:30 am in Hussey with Igor Jovanovic) . 94 6.4.3 Poster IV - Physics, Security Applications, and Signal Processing (Thursday 9:30 - 10:30 am in Ballroom with Angela Di Fulvio) . 96 6.4.4 Space and Nuclear Physics Applications (Thursday 10:30 - 12:00 pm in Mendelssohn with Zhong He) . 112 3 6.4.5 Scintillation Detectors III (Thursday 10:30 - 12:00 pm in Hussey with Marek Flaska) 113 6.4.6 Liquid Detectors for Neutrino Detection and Gas Detectors for Nuclear Physics (Thursday 1:30 - 3:00 pm in Mendelssohn with Zhong He) . 115 6.4.7 Radiation Detection using Mobile/UAVs (Thursday 1:30 - 3:00 pm in Hussey with Simon Labov) . 116 6.4.8 Plastic Scintillators (DNDO projects) (Thursday 3:30 - 5:00 pm in Mendelssohn with David Wehe) . 118 6.4.9 Active Interrogation Techniques (Thursday 3:30 - 5:00 pm in Hussey with Namdoo Moon)........................................... 120 7 Maps 122 7.1 Michigan League . 122 4 1 Exhibitors In League Ballroom ADIT Electron Tubes APL Engineered Materials Brekeley Nucleonics Corp CAEN CapeSym Eljen Technology H3D Hellma Materials Hilger Crystals Inrad Optics Niowave Nuctech Saint-Gobain Scintacor Scionix SensL Startfire Industries WIENER Power Electronics XIA In Michigan Room Alpha Spectra Inc Grirem Advanced Materials Hamamatsu ORTEC PHDS Silverside Detectors SpectralLabs 5 6 2 Social Programs Monday 6:00 pm - 8:00 pm Opening Reception - Michigan League The Opening Reception will be held at the Michigan League in the Vandenberg and Hussey rooms on the second floor next to the registration table.
