Jellison, Sr. Contract Administrator E-MAIL: Click here to contact the contracting administrator via e-mail., jellison1@llnl.gov. The University of California, Lawrence Livermore National Laboratory, seeks sources for a Prototype Incoherent Fiber Bundle to be used in the National Ignition Facility (NIF). NIF is a $1.2 billion U.S. Department of Energy (DOE) laser facility which will be used for Inertial Confinement Fusion (ICF) research. The laser consists of 192 Nd-glass beamlines delivering 2 x 106 joules at a wavelength of 1.053 m. LLNL and other DOE laboratories are currently in the detail design phase of this project. The laser diagnostics design group has need to transmit pulsed analog optical signals (wavelength = 1.053 m) from remote sensing locations to centralized recording instrumentation. For a variety of reasons we have determined that 100 m core graded-index fiber bundles are necessary to meet system design requirements. At the output end, signals from several of these optical delay line bundles will be simultaneously input on to a small area sensor; therefore small bundle ends are required. Bundles in several lengths are required in order to achieve time multiplexing of the signals. In addition, since these bundles will be used in temporal measurements, control of the lengths of the individual fibers within a bundle will be necessary in order to limit temporal dispersion to * 50 ps. At this time we are interested in determining vendor interest in fabricating such fiber bundles. Comments as to how best to fabricate these delay lines are solicited. Included in this is a need to establish rough cost estimates and, if necessary, changes in bundle specifications which would lead to reduced costs. A prototypical bundle(s) will be purchased later this year. Production quantities (approximately 500 bundles) are expected to be purchased towards the end of 1998. Present designs utilize several bundle lengths ranging from 3 to 27 meters. Prototype Requirements: Number of fibers in bundle: 19 (1 broken fiber allowed) Bundle length: 27m 5cm Individual fiber length difference within bundle: 0.5cm (i.e., 25 ps transit time dispersion) Fiber type: Graded-index, 100 m core diameter, 140 m cladding diameter Bundle ends: Close pack (our goal is to have a 19 fiber bundle fixed in a tube * 1mm in diameter, fibers polished at each end and 6" strain relief at each end. Bundle jacketing: Flexible steel conduit, International Metal Hose type "IC" or equivalent Documentation: Photo of each end with opposite end illuminated. Interested firms should respond indicating interest, description of qualifications and commenting on requirements and ways to simplify and/or clarify. Please indicate cost per bundle (for prototype and production quantities) based on the existing requirements and what requirements changes would lead to lower costs. The Small Business size standard applicable to the proposed acquisition is 1,000 employees. Firms qualifying as a Small Business with respect to this standard should so state. Responses are required on or before July 15, 1997. Firms responding to this announcement which fail to provide the required information will not be considered for inclusion into any resulting source list. Facsimile and telephone responses will not be accepted. This notice is to assist the University in determining the potential for competition; no solicitation is currently available.***** (0167)
