66 -- LOW ENERGY ION BEAMLINE SUBSYSTEM SOL N00014-95-R-GP07 POC Geoffrey Pennoyer, Contract Specialist, Code 3220.GP, Contracting Officer, Wayne A. Carrington (202) 767-2550. The Navy Research Laboratory has a requirement for a low-energy-ion beamline. This will be one of six subsystems that will comprise a to-be-built Trace Element Accelerator Mass Spectrometer (TEAMS). The TEAMS low energy ion beamline must be compatible with an existing tandem ion accelerator facility which is a National Electrostatics Corporation 9SDH-2 machine purchased in 1987 with a 3 MV terminal potential. The subsystem will consist of the following line items, doubly achromatic single magnet with a dispersed image plane (also known as a Pretzel magnet, or an Achromatic magnetic mirror, or a Recombinator), Einzel lens equal to National Electrostatics Corporation Model No. EL44-50 - Part No. 2EA061550, X-Y Electrostatic Steerer/Pump Tee equal to National Electrostatics Corporation Model ES5 - Part No. 2EA060252, HV DC Power Module equal to Glassman Model No. MK50N1.5, Compact Full Range Vacuum Gauge equal to Balzers Model PKR 250 - Part No. BG G20 002, cryopump with accessories, two vacuum bellows, two gate valves, flanges and flange hardware. Optional components are, Electrostatic Steerer/Pump Tee equal to National Electrostatics Corporation Model No. ES5 - Part No. 2EA060251, cryopump with compressor and accessories, three gate valves, a welded metal bellows, a custom vacuum chamber, a Faraday cup, flanges and flange hardware, two Compact Full Range Vacuum Gauges equal to Balzers Model PKR 250 - Part No. BG G20 002, a tesla meter equal to a Group 3 Technology LTD Model DTM-141-PS, Probe for teslameter equal to a Group 3 Technology LTD Model LPT-141-7, a vacuum tee, a beamline insulator, and two picoammeters. This subsystem must be capable of low-energy-ion transport, filtering, and injection into the NEC accelerator. It must be self-contained and integrate completely with the other five TEAMS subsystems and the existing facility. An overriding consideration in all of these subsystems is the necessity to transmit as much of the beams of interest as possible (100% is desired). Each ion optical component is to include ion optical elements, internal support structures, alignment tools, vacuum changer and flanges, manuals and safety protection devices to enable useful operation of the equipment. Telephone requests for this requirement will not be honored. If a non-availability notice is desired, furnish a self-addressed envelope.
