R -- PENNING TRAP EXPERIMENTS SOL NB847-700436DT POC Doris Turner, Purchasing Agent, (303) 497-3872 or FAX (303) 497-3163 E-MAIL: NOAA; MASC Acquisition Management, Doris.P.Turner@noaa.gov. The National Institute of Standards and Technology (NIST) requires a continuation of services for a project to trap and sympathetically cool positrons in a Penning trap by laser-cooled Be+ ions. Tasks are to include the following. 1. Finalize the calculation of the efficiency of positron trapping. In particular the effects of the energy spread of the moderated positrons and the density of the laser-cooled Be+ ions of the efficiency should be determined. 2. Design, construction, and installation of shielding about the magnet to insure radiation from the positron source is at an acceptable level. 3. Design and installation of the positron source, including a modulator for this source. 4. Determination of the trapping efficiency of positrons and effectiveness of sympathetic cooling. Interested sources proposing to supply an equivalent unit must submit pricing with a written qualification statement clearly establishing capability to meet the above requirements within 15 days from the date of this synopsis.The qualifications statements will be used to determine the need for competitive bids. In the absence of other qualified sources, it is the intent of the Government to award a sole source contract under the authority of 41 U.S.C. 253(c)(1) to Brana Jelenkovic, 1205-B Bear Mountain Drive, Boulder, CO 80303 as this source is considered to be the only responsible source and no other equipment will satisfy agency requirements. Responses are due by September 3, 1997 either via fax or mail. No RFQ package is available. (0231)
