66 -- JSTM-4600/ULTRA HIGH VACUUM SCANNING TUNNELING MICROSCOPE W/SEM SOL F04700-95-R-0022 DUE 062795 POC Shirley Jones, Contract Specialist, (805) 277-3900 X2269, John C. Lemacks, Contracting Officer, (805) 277-3900 X2253. The Phillips Laboratory at Edwards AFB, California, has a requirement for an ultra high vacuum variable temperature microscope that incorporates simultaneous scanning tunneling microscopy (STM), scanning electron microscopy (SEM) and sample heating to 1200 degrees C. Characteristics: (1) High vacuum observation chamber operates at 10-8 Pa and includes 300 1/sec ion pump, 1600 1/sec Ti sublimation pump, ion gauge, built-in heater for SEM, and viewports. (2) Specimen exchange chamber operates at 10-6 Pa and includes built-in heater for baking to 200 degrees C, 100 1/min roughing pump, 60 1/sec storage for one tip and one sample. (3) Integrated anti-vibration device consists of built-in vibration table, built-in auto pressure regulator, gimble piston air suspension, and transverse vibration stopper. (4) STM stage consists of course sample movement of + or - 1 mm in both x and y direction, z-range of 0.5 mm, auto approach, tip collision prevention, resolution of 0.14 nm horizontal and 0.01 vertical, Z-retraction, piezoscanning of 0.2 microns in X and Y and 0.3 microns in Z-direction, zoom function and drift less than 0.06 nm/sec. (5) Speciman heater can heat sample to 1200 degrees C for STM observation. (6) SEM specifications include: resolution to 5nm, magnification from 15X to 200,000X, 3 stage lens system, and 3-step objective lens aperature. Computer control system shall consist of 32 bit computer with 512 X 512 X 8(bit) frame store, high speed 12-bit AD/DA converter, high resolution color CRT, and computer table. Software shall consist of control software, image processing software, and STS software. Requirement includes shipping and rigging to Building 8424, Phillips Laboratory, Edwards Air Force Base, California; installation; basic operating training concurrent with installation; and on-site training for up to five persons for a duration of up to five days no later than two weeks after installation. Using the authority of 10 U.S.C. 2304(c)(i) pursuant to FAR 6.30-1(a)(2), it has been determined that the required equipment is available from only one responsible source and no other type of equipment will satisfy agency requirements. The AFFTC intends to sole source the requirement with JEOL USA INC, Peabody, MA, unless responses to this notice reveal other sources capable of satisfying the requirement. Interested sources must submit clear and convincing evidence, to include descriptive literature, and evidence of prior sale of the unit, to meet the Government's requirement no later than 7 May 95. NO TELEPHONE REQUESTS WILL BE ACCEPTED. (0082)
