66 -- CRYO-RADIOMETER CONTROL ELECTRONICS SOL 52SBNB6C9175 POC Brenda K. Lee (301) 975-6394 The National Institute of Standards and Technology (NIST), intends to negotiate with Cambridge Research Instrumentation Inc, 21 Erie Street, Cambridge, MA 02139, on a sole source basis to acquire a Cryo-radiometer Control Electronics to include a low noise electronics box (ac bridge), control unit, cables, operational software, and IEEE interface Model TC-02. The Government also requires one year warranty to include parts and labor. FOB destination, Gaithersburg MD-- Required delivery within 30 days after contract award-- This is a sole source procurement in accordance with FAR 6.302.1, Only One Responsible Source, because the Cambridge Cyro-radiometer Control Electronics, Model TC-02 is the only source that meets all the required specifications for operation with the High Accuracy Cryogenic Radiometer (HACR). The specifications which only Cambridge can meet are as follows: The system shall have a thermometry bridge stability better that five microKelvin (and better than three PPM per degree C), the lower this value the better. Included in theses electronics are two servo controlled heater systems (temperature controllers) that actively control heaters to maintain temperature stability. The electronics for the heater system shall be able to provide power in the range of a few nanowatts to over 4 mW. The accuracy of the heater powers should be better than 100 PPM over the period of a day. The temperature controller shall be interchangeable with a previously existing temperature controller TC-02 systems in the division. The system shall be compatible with the existing programs as well as interface with existing hardware and cabling used to run the CRI TC-02.Interested offerors may identify their interest and capability to respond to the requirements by submitting a capability statement. The capability statement must provide adequate information and qualifications of your ability to provide the requested system in order for the Government to consider whether to open this request for competition. However, all capability statements received within 45 days after date of preparation of this synopsis, will be considered by the Government. See Note Numbered 22 (0156)
