59 -- CCD IMAGER ELECTRONICS SOL RFQ2-36680-SLC DUE 082098 POC Sharon L. Connolly, Contracting Officer, Phone (650) 604-6927, Fax (650) 604-4646, Email sconnolly@mail.arc.nasa.gov WEB: Click here for the latest information about this notice, http://nais.nasa.gov/EPS/ARC/date.html#RFQ2-36680-SLC. E-MAIL: Sharon L. Connolly, sconnolly@mail.arc.nasa.gov. THIS NOTICE CONSTITUTES AMENDMENT NO.1 TO THE COMBINED SYNOPSIS/RFQ FOR CCD IMAGER ELECTRONICS. Companies shall acknowledge all amendment(s) in their quote. This notice serves as the official amendment to subject synopsis/RFQ and a written amendment will not be issued. The purpose of this amendment is to provide additional information to all interested quoters as a result of questions submitted: Question: Will the Imager be in an inside laboratory setting or an outside setting? Answer: The imager will be used in an astronomical observatory. The observatory dome will open to the weather every night that it is not rainy or foggy. Question: What will the ambient temperature be? Answer: The ambient temperature at night in the summer occasionally gets as high as 26 degrees Centigrade. In the winter, the temperature occasionally gets as low as -5 degrees Centigrade. Question: Will the Imager require an air heat exchanger or refrigerant chilled water or coolant? Answer: Similar imagers need a chilled liquid refrigerant to maintain the CCD at -35 degrees Centigrade. If the quoter can keep the CCD at -35 C with an air exchanger, that is also acceptable. However, the system must not induce significant vibrations into the imager. The due date for receipt of offers is not extended. Companies shall provide the information stated in the synopsis/RFQ posted on the NASA Acquisition Internet Service (NAIS) on August 04, 1998. Documents related to this procurement are available over the Internet and are in Microsoft Office Suite (Word 6.0, Excel 5.0, or PowerPoint 4.0) format and reside on the World Wide Web (WWW) server which may be accessed using a WWW browser application.
