59 -- LARGE SCALE HIGH VOLTAGE CAPACITORS POC Margaret Cooke, Senior Subcontract Administrator (510) 423-2178 The University of California Lawrence Livermore National Laboratory (LLNL), in collaboration with Sandia National Laboratory, Albuquerque (SNLA) and as representatives of the National Ignition Facility (NIF) Project, a multi-laboratory effort of the Department of Energy (DOE), is seeking manufacturing sources for large scale High Voltage Capacitors to be used to power flashlamps used in large Nd:glass amplifiers for the NIF lasers. These capacitors will be single bushing configuration with a grounded case terminal and have maximum physical dimensions of: 91cm (36'') long, a bushing face of 41cm (16'') wide x 41cm (16'') high and a bushing height of 5cm (2'') maximum from the bushing face. They must be of the self healing dielectric system type. Electrical characteristics of the capacitors are: Capacitance: 290 microfarads, +10%, -5%. The nominal charge voltage: 24kV. The normal output current must be 26 kA, 1/2-sine discharge, less than 10% reversal. The fault output current must be 85 kA, ringing discharge, 60% reversal on first cycle. The output pulse width must be 360 microseconds. The Internal Resistance: less than 5 milliohms at 1.4kHz. Internal Inductance: less than 1 microhenry. Operating life must be at least 20,000 charge cycles normal operation, plus 25 charge cycles fault mode operation. Required operating repetition rate: 1 charge cycle per 15 minutes. Desired repetition rate: One charge cycle per minute. Maximum charge time: 60 seconds. Maximum hold time: 15 seconds. Approximately 4000 of these capacitors are required for NIF. Interested firms must respond with a written statement of capabilities, available resources, and qualifications. Respondents must also include information which documents past capability to manufacture similar capacitors of this type and size. Test data on such units must be provided to LLNL upon request. Responses which include the required information must be received by LLNL on or before January 10, 1996. Firms responding to this announcement that fail to provide all the required documentation will not be solicited for a proposal. Facsimile and telephone responses will not be accepted. The small business size standrd applicable to the proposed acquisition is SIC 3629, or 500 employees. Firms qualifying as a small business with respect to this standard should so state. This notice is to assist the University in determining the potential for competition; no solicitation is currently available, nor is funding currently allocated for this requirement. This synopsis will be used only as part of the market survey process. Again, no solicitation is currently available, and there is no currently planned release date for one should one be developed.
