66 -- SOFT X-RAY DETECTOR WITH ENERGY DISCRIMINATION SOL N00173-98-R-JR07 POC Jerry Riles, Contract Specialist, Code 3220.JR, (202) 767-2120, Wayne Carrington,Contracting Officer WEB: click here, http://heron.nrl.navy.mil/contracts/home.htm. This is an amendment to a combined synopsis/solicitation for commercial items prepared in accordance with the format in Federal Acquisition Regulation Subpart 12.6, and issued on 12 May 1998. This announcement constitutes an amendment to solicitation, N00173-98-R-JR07, for a Soft X-ray Detector with Energy Discrimination. This amendment is issued to provide a response to questions submitted against the synopsis/solicitation. Question (1): Please provide further clarification on the Cu support with parylene as requested in part (iv) if the solicitation. Is this a commercially available product that can be identified by the end-user? Response: To the Technical Representative's knowledge, this item is not commercially available product because it depends on the construction of the detector housing and detector retraction mechanism. Question (2): Is the Cu support a grid pattern or a solid structure? Response: The Cu support is envisioned to be a Cu mesh to maximize soft x-ray transmission while maintaining window integrity during detector operation and chamber venting. Question (2): Please clarify the placement of the parylene window. Response: The vacuum barrier window is placed between the detector elements and the sample position and serves to maintain a vacuum differential between the detector elements and the sample chamber. In this way, an ultra high vacuum environment for the detector elements can be maintained even if the sample chamber vacuum is not ideal (during sample transfer, sample cleaning, etc.). Any questions generated, as a result of this solicitation must be received no later than 10 days before the closing date. Original and two (2) copies of the Offerors proposal must be delivered to Contract Officer, Code 3220:JR, Bldg. 222, Rm. 115A, Naval Research Laboratory, Code 3220:JR, 4555 Overlook Ave. S.W.
