66 -- SILICON DETECTOR DEVELOPMENT SOL 691-77226 DUE 071800 POC Jeanne V. Moschetti, Contract Specialist, Phone (301) 286-3227, Fax (301) 286-1773, Email jmoschet@pop100.gsfc.nasa.gov WEB: Click here for the latest information about this notice, http://nais.msfc.nasa.gov/cgi-bin/EPS/bizops.cgi?gr=D&pin=51#691-77226. E-MAIL: Jeanne V. Moschetti, jmoschet@pop100.gsfc.nasa.gov. This procurement is being conducted under the Simplified Acquisition Procedures (SAP). NASA/GSFC intends to purchase the items from Photo Imaging, Inc. in Northridge, CA. on a sole-source basis for Silicon Detector Development. This purchase order will provide for two types of silicon detectors as x-ray and photodiode detectors for a variety of possible space applications. Photo Imaging is uniquely qualified to perform this effort because they are the proprietor of phase 1 and 2. The multi-channel silicon strip detectors are 0.5 -- 1 cm 2 in area, and contain 100-200 linear strips that each function as individual radiation detectors. The detectors will be characterized with respect to: 1. current-voltage response, 2. response to x-rays in the 1 -- 20 ke V range using radioisotope sources and fluorescence from foils excited by an x-ray generator, 3. noise, and 4. energy resolution as a function of temperature from -20 C to 25 C. The Government does not intend to acquire a commercial item using FARPart 12. See Note 26. Interested organizations may submit their capabilities and qualifications to perform the effort in writing to the identified point of contact not later than 4:30 p.m. local time on 7/18/00. Such capabilities/qualifications will be evaluated solely for the purpose of determining whether or not to conduct this procurement on a competitive basis. A determination by the Government not to compete this proposed effort on a full and open competition basis, based upon responses to this notice is solely within the discretion of the government. Oral communications are not acceptable in response to this notice. All responsible sources may submit an offer which shall be considered by the agency. An Ombudsman has been appointed.
