58 -- FABRICATION OF COUPLED CAVITY TUBE/TRAVELING WAVE TUBE FOR THE HAYSTACK RADAR POC Themoula Poirier, Contracting Officer, 617-377-9457; Lt. Matthew Wojewuczki, Technical POC, 617-377-9483. The Government intends to award, on a sole source basis, options for fabrication, test and delivery of three VTX-5681B1 Coupled Cavity Tube/Traveling Wave Tubes (CCT/TWTs) for use by the Haystack Radar. This is a requirement under an existing effort awarded to Communications & Power Industries (CPI) Microwave Power Tube Products Division on 12 September 1996. The Government intends to solicit and negotiate with CPI using other than full and open competition procedures pursuant to 10 USC 2304(c)(1) as implemented by the Federal Acquisition Regulation 6.302-1. Under previous contracts, CPI has developed the VTX-5681B1 TWT and is currently the only source with the requisite knowledge and capabilities required to meet the Government's requirements. CPIs proprietary design of these tubes is unique in many of the high power design features it incorporates. In order to achieve peak and average power requirements, special sever loads, windows and high power circuit designs are required. These are specifically designed for the thermal load management of the device. The phase requirements are satisfied with a waveguide gain equalizer that was designed in conjunction with an electron beam system which allows these tubes to operate with a connected beam supply. CPI has the proven expertise in the fabrication of this type of TWT. The Government intends to award this action as a Supplemental Agreement to Contract No. F19628-96-C-0160 under which CPI is currently providing the same type of TWT. Not withstanding the above, if your firm believes it could accomplish this effort in the required schedule (each tube must be delivered within 12 months from option execution), submit a qualification package to the above address not later than 15 days from the publication of this notice. The Government anticipates contract definitization during the second quarter of fiscal year 1997. See Numbered Note(s): 22, 25, 26. (0325)
