66 -- BISMUTH GERMANATE COMPTON SUPPRESSOR SOL 40SBNB060103 DUE 061400 POC Paul G. Cataldo, Contracting Officer, (301) 975-6332, or Anne McFarlane, Contract Specialist, Tel (301) 975-4648, FAX (301) 963-7732, e-mail anne.mcfarlane@nist.gov WEB: NIST Contracts Homepage, http://www.nist.gov/admin/od/contract/contract.htm. E-MAIL: NIST Contracts Office, Contract@nist.gov. THIS IS A COMBINED SYNOPSIS/SOLICITATION FOR COMMERCIAL ITEMS PREPARED IN ACCORDANCE WITH THE FORMAT IN FAR SUBPART 12.6, AS SUPPLEMENTED WITH ADDITIONAL INFORMATION INCLUDED IN THIS NOTICE. THIS ANNOUNCEMENT CONSTITUTES THE ONLY SOLICITATION; QUOTES ARE BEING REQUESTED AND A WRITTEN SOLICITATION WILL NOT BE ISSUED. **** The National Institute of Standards and Technology (NIST) has a requirement for a Bismuth Germanate Compton Suppression System with the following specifications: 1) The basic dimension of the BGO should be 5" x 5" x 7". If not made from a single crystal, a maximum of two crystals shall be used and each piece should be full length. 2) The diameter of the cylindrical well in the BGO must be 3.125" to accommodate a 3" diameter end-cap Ge detector. The length of the cylindrical well, drilled at a right angle to the long axis of the BGO, should be 3.9". 3) The cylindrical window allowing the Ge detector to view the sample is drilled along the center axis of the BGO, and at a right angle to the Ge detector well, shall be 0.875" in length with a 1.2" diameter. This provides 0.875" of BGO between the sample and Ge detector. This face may be beveled to enhance light collection. 4) There shall be approximately 3" of BGO between the photomultiplier tube (PMT) and the Ge detector (behind the Ge detector). 5) The BGO shall be encased in light and moisture tight aluminum and have a reflective interior. 6) One standard 5" PMT with preamplifier. This system is used in a very high background area, with gamma rays ranging in energy from 100 keV to 10.8 MeV. A low background PM tube is not required but good stability with high count-rates is needed. 7) The BGO will be used with an up-looking germanium detector which detects gamma rays from a sample placed at a distance of 12" to 18" to the side of the detector, i.e. at 90 with respect to the cylindrical axis of the germanium crystal.****A drawing is provided for clarification of the dimensions required.
