66 -- MULTI-CHANNEL DETECTOR SOL F19650-95-R-0188 DUE 082595 POC Amanda Burgess, Buyer, 617-377-7060; John Sorgini, Contracting Officer, 617-377-2579; John Miller, Branch Chief, 617-377-2195. The contractor shall provide and install a multichannel detector to a surface analysis system currently in use, the Physical Electronics ESCA System. The required multichannel detector shall consist of a Physical electronics Model 3057-AD-03 multichanel detector, or equivalent, to replace the existing single-channel detector. The multichannel detector shall be completely controlled by the Physical Electronics Version 3.0 software currently in use. The multichannel detector shall be installed on the exisitng surface analysis system, along with installation of the following Government-supplied equipment: a variable aperture small area lens, a sample viewing kit, and replacement of the thermocouple on the current sample holder. All installed equipment shall be aligned to the sample holder to maximize the count rate. The contractor shall verify proper system operation. The multichannel detector shall include a 16-channel amplifier/discriminator, computer-controlled data acquisition system hardware, a 16-bit IBM PC-compatible interface board, all required electronic hardware (cable kits, etc.), and all relevant documentation. The multi-channel detector shall fully interface with the existing Physical Electronics Model 10-360 Hemispherical Energy Analyzer. The system shall have the following specifications: 16-channel Amplifier/Discriminator Physical Electronics Model 160 or equivalent; shall have sixteen channels, AC coupled input, discrete amplifier/discriminator counters with maximum count rates of at least 20,000,000 counts/second (cps). Data Acquisition System Hardware Electronics Physical Electronics Model 74-500 or equivalent; shall control the multichannel detector and interface with the controlling computer (IBM PC); shall have sixteen counters and memory adequate to record and save 16 data streams simultaneously. Computer Interface Physical Electronics Model 257 Dual DR11/AT or equivalent; shall be compatible with a 16-bit ISA slot in an IBM-compatible PC; shall have two 16-bit DR11-C ports, 16 handshake lines, and a timer; run on +5 volts, 1.2 amps; timer frequency of 10MHz divided to 100KHz on board; 10olms to 655ms timer range, 10olms steps. The contractor shall install, calibrate, and test the multichannel detector system on the exsisting vacumn chamber. The contractor shall install government-supplied equipment consisting of a Physical Electronics Model AL-05 OMNI Focus Small Area Lens Variable Aperture option. The contractor shall install government-supplied equipment consisting of a Physical Electronics Sample Viewing Kit, which includes a Physical Electronics Model 04-035 Microscope and a Physical Electronics Model 03-100 Light Source. The contractor shall repair or replace the thermocouple on the existing sample mounting stage. The contractor shall install government-supplied equipment consisting of a Physical Electronics Model 04-015 5 kV electron gun and Model 11-010 5 kV electron gun control. The contractor shall provide all operation/periodic maintenance manuals required for all delivered components and subsystems. System performance shall be verified by total counts of 3,500,000 cps (above background) for a resolution (FWHM)of 1.0eV at a slit size of 0.8mm x 2.0mm, and 2,500cps for a resolution of 1.0eV at a slit diameter of 75 olms, both for the Ag3d 5/2 peak using a Mg anode operated at 26.7 mA and 15KV. Firms responding to this announcement shall specify whether they are or are not a small, a small disadvantaged, or women owned business concern. (0163)
