The Uniformed Services University of the Health Sciences (USUHS), the Department of Defense Medical School and Health Sciences University, hereby announces its intent to acquire, on a sole source basis from Canberra Industries, Inc. in Meriden, CT, a Reverse Electrode Germanium Detector, an InSpector 1000, a Falcon 5000, and various accessories and components for the Armed Forces Radiobiology Research Institute (AFRRI). The items are as follows: 1) Reverse Electrode Germanium Detector 2) Vertical Slimline Dipstick Cryostat 3) Carbon Fiber Detector Window 4) Cryo-Cycle Cooler 5) LabSOCS Characterization of Canberra Detector 6) LabSOCS Efficiency Calibration Software 7) X13660-2 HP 3600N Color Printer 8) On-Site Installation/Familiarization 9) InSpector-1000 Digital Hand Held MCA 10) InSpector-1000 Car Adapter/Charger 11) Hard Case for Inspector 12) ISOCS/LabSOCS Characterization of LaBr 13) Falcon-5000 Portable HPGe System 14) Falcon-5000 Control Computer- Rugged 15) Screw-On Tungsten Collimator 16) Spare Internal Li-Ion Battery 17) 100-240V AC Charger for one Li-Ion Battery 18) Falcon-5000 Control Computer- Tablet The Reverse Electrode Germanium Detector (REGe) and InSpector 1000 is a multichannel analyzer (MCA). These units provide the capabilities to evaluate radiological material as well as identify unknown radiological material. The InSpector 1000 would provide capabilities to detect neutrons as well. This could enhance identification of radiological substances. It also allows initial assessment of dose response to estimate wait times and type or radionuclide. The Falcon 5000 is a portable system that can provide capabilities of initial radiological evaluation. The unique capabilities of this system would provide dose assessment and identify radionuclides which may be present. All items to be acquired are compatible with the table top system currently utilized by AFRRI: Multiple Germanium detectors Two Lynx MCA systems Multiple copies of Genie-2000 acquisition control and analysis software LabSOCS efficiency correction software Laboratory procedures and training are centered on the above listed Canberra equipment. The Canberra Germanium detector will be delivered with a liquid nitrogen cooling system where the evaporating nitrogen gas is re-liquefied and forced back into the storage container (dewar). This allows the system to be run almost indefinitely. Canberra is the only vendor with this re-liquefying technology. The detector will be mathematically characterized for use with existing Canberra Laboratory Sourceless Calibration Software (LabSOCS). This allows AFRRI the ability to analyze samples without having previously purchased a calibration standard in the exact shape and matrix as the unknown sample. This greatly expands AFRRI’s analysis capability in that almost any unknown sample can be analyzed. Canberra is the only vendor which offers this technology. The detector will be connected to an existing Canberra Lynx multichannel analyzer (MCA) and Genie-2000 software and as such must operate as a system. Canberra is the only vendor who will guarantee complete system performance due to issues of compatibility. The LabSOCS software (Item 6) will be the second copy purchased by AFRRI. No other vendor offers an equivalent product and this software must be compatible to the one already in use. The InSpector-1000 (Items 1-12) is a handheld isotope identifier. It is the only unit on the market which offers: a) LaBr detector technology for increased resolution over NaI detectors. b) Simultaneous neutron detection capability along with gamma detection. c) LabSOCS characterization of the LaBr detector. d) The data file format is identical to the equipment currently in use at AFRRI, namely the Genie-2000 spectroscopy software. This is critical for data and analysis compatibility. The Falcon-5000 (Items 13-18) is a Germanium detector-based identifier and is the only unit on the market which offers: a) Canberra’s Genie-2000 software as the user control interface and for analysis. b) Up to 8 hours of operation on a single charge of the two internal batteries. c) “Hot swappable” batteries for continuous operation. d) Detector cool down time of less than 3 hours. This is critical for quick deployment. e) The ability to detect gamma rays down to 5 keV. This is important for radionuclide identification of low energy isotopes. Competitive units can detect only as low as 40 keV. f) Cooling technology which is virtually vibration free which improves the resolution of the spectra. This results in much better Minimum Detectable Activities and also a better opportunity to resolve adjacent peaks and thus different isotopes g) The Falcon can be fully operated from a remote location. Competitive units require an operator be present at the unit. This may be hazardous when used in a high background radiation environment. h) Automatic email transmission of data and results after a count. i) Fully automated and customizable analysis via the imbedded Genie-2000 software. Competitive units restrict analysis to only what is hard coded internally. j) Removable shielding to reduce background radiation levels and restrict the field of view of the detector to only the sample. This award is IAW FAR Part 13.106(b) and authorizes USUHS to award contracts when only one source and no other supplies or services will satisfy agency requirements.
