A -- ANALYSIS OF THE INTERACTION OF RADIATION WITH NON-LTE PLASMAS SOL N00173-00-R-JW02 POC James P. Waldenfels, Code 3240.JW 202-767-3003, waldenfels@contracts.nrl.navy.mil; Contracting Officer Carol Parnell WEB: htt://heron.nrl.navy.mil/contracts/home.htm, http://heron.nrl.navy.mil/contracts/home.htm. The Naval Research Laboratory has a requirement for analysis of the interaction of radiation with non-LTE plasmas. This requirement will be set aside on a 100% basis for small business concerns under SIC Code 8731. NRL's Laser Plasma Branch has a large research effort to study the interaction of intense laser beams with dense plasma targets, as part of its multi-year laser fusion program. This contract will provide support services to develop new atomic physics opacity/emissivity modeling of plasmas in non local-thermodynamic-equilibrium (non-LTE). This requires further development of existing models, developing new analytic models, and programming these models with very large computer codes. The new models should be based on state of the art LTE opacity models, taking into account realistic radiation fields. A CPFF term type contract with a base year and four option years is contemplated, with 3,500 hours in the first year and 4,500 in option years for a total of 21,500 hours. A start date of approximately March 15, 2000, is anticipated. Anticipated personnel include a senior physicist (2,000 hours each year), a physicist for 1,000 hours the first year and 2,000 in subsequent years, and a physicist for 500 hours each year. All performance is anticipated at NRL for the first two positions and off-site for the latter position. ARTEP, Inc. of Columbia, MD is currently performing such services under an existing contract. A detailed sow will be issued with the solicitation. Proposals will be due approximately 30 days after the solicitation is issued. NRL uses Electronic Commerce (EC) to issue RFPs and amendments to RFPs. This solicitation and any amendments to it will be available via the Internet at the URL address shown below. Paper copies of the RFP will not be provided. Numbered Notes 1 and 26 apply. 1. The proposed contract is 100% set aside for small business concerns. 26. Based upon market research, the Government is not using the policies contained in Part 12, Acquisition of Commercial Items, in its solicitation for the described supplies or services. However, interested persons may identify to the contracting officer their interest and capability to satisfy the Government's requirement with a commercial item within 15 days of this notice.
