59 -- PULSED POWER BALLAST INDUCTOR ASSEMBLIES 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 pulsed power ballast inductor assemblies for flashlamps used in large amplifiers for fusion lasers. Twenty of these inductors are to be arranged in a junction box that distributes 500 kA of input current to 20 series-pairs of flashlamps operating in parallel. The junction boxes approximate physical dimensions are: 91cm (36'') long x 91cm (36'') wide x 61cm (24''). The Total Inductance of each installed inductor in the assembly must be 30 microhenries +/- 5%. The Nominal Operating Voltage shall be 24 kV. The Peak Output Voltage (ring-up) shall be 50 kV. The Normal Operating Current shall be 26 kA, 1/2 sine discharge, less than 10% reversal. The Fault Operating Current shall be 100 kA, ringing discharge, 60% reversal on first cycle. The Output Pulse Width is 360 microseconds. The Resistance must be 20 milliohms at 1.4 kHz +/- 10%. The Operating Life must be at least 20,000 shots normal operation plus 25 shots fault mode operation. Required Operating Repetition Rate: One shot per 15 minutes; Desired Repetition Rate, 1 shot per minute. Approximately 200 of these assemblies, plus spares, 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 standard applicable to the proposed acquisition is SIC 3629, or 500 employees. Firms qualifying as a small business with respect o 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.
