R -- PENNING TRAP EXPERIMENTS SOL NB847-800278DT POC Doris Turner, Purchasing Agent, 303-497-3872; 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. Determine both theoretically and experimentally, the heating resonances produced by the Be+/e+ Penning trap asymmetries. These asymmetries should be minimized to permit operation of the trap at high densities. 2. Implement the "rotating wall" technique on the Be+/e+ Penning trap. This technique should stabilize the plasma rotation frequency and requires a careful balance between the torques due to the rotating electric field (the rotating wall) and the cooling laser beam. 3. Investigate and measure the change of plasma shapes with an anharmonic contribution of the trap potential -- in particular, if hollow distributions are caused by a 4th order anharmonic term. 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 others will satisfy agency requirements. This announcement is being issued under the Simplified Acquisition Procedures, FAR Part 13 (NTE $100,000.00). The award decision will be based upon the best value to the Government, with technical merit and past performance being significantly more important than price. Terms and conditions and agency level protest procedures are referenced at http://netsite.esa.doc.gov. Responses are due by June 3, 1998 either via fax or mail. No RFQ package is available. (0138)
