This notice is a combined synopsis/solicitation for commercial items prepared in accordance with the format in FAR Subpart 12.6, as supplemented with additional information included in this notice. This announcement constitutes the only solicitation; quotes are being requested and a written solicitation will not be issued. This procurement is being conducted under the Simplified Acquisition Procedures (SAP). This notice is a combined synopsis/solicitation for commercial items prepared in accordance with the format in FAR Subpart 12.6, as supplemented with additional information included in this notice. This announcement constitutes the only solicitation; quotes are being requested and a written solicitation will not be issued. This procurement is being conducted under the Simplified Acquisition Procedures (SAP). ONE EACH OF A Variable Temperature Low Vibration Sample In Vacuum Optical Closed Cycle Refrigerator System. * <15K to 325K Operating Temperature Range * 5 Watts Nominal Cooling Power At 20K * 20 Watts Nominal Cooling Power At 77K * A mechanical refrigerator coldhead with sealed helium gas as the refrigerant medium. A heater and sensor installed on the tip of the coldhead which allows the operating temperature to be varied between 10K and 325K * An air-cooled compressor that compresses helium gas to approximately 16 atmospheric pressure and injects the high pressure gas into the coldhead by means of a flexible stainless steel hose. A low pressure stainless steel hose line returns the expanded helium gas back to the compressor to complete the cycle. * 10 feet interconnecting hoses and control cable * 2.00 inch diameter clear optical quartz window * 2.50 inch diameter vibration damped sample mount * 4.25 inch outside diameter (4.18 inch inside diameter) radiation shield * 7.00 inch from sample mount to radiation shield base * 10-pin electrical feedthrough * (3) spare blank feedthrough ports * External bellows vibration isolation assembly * Evacuation valve with safety pressure relief * Startup toolkit with operation manuals 2. (4 each) Demountable calibrated silicon diode temperature sensors * Installed and tested on coldhead, sample mount, and for mounting on users test article. * 1.4K to 325K calibrated temperature range +/- 50 mK accuracy 3. Multiple channel autotune temperature controller which coupled to the feedback from the temperature sensor will output a control current to the heater to regulate the temperature to a set value. * 20 bit ADC * 3 Term PID control and table modes * Dual heater outputs (50W digital, 1W analog) * Eight sensor inputs * 10 microamps to 1 milliamp DC sensor excitations * IEEE-488 and RS232 computer interfaces * Fully integrated and tested with system 4. Autocontrol windows software * IEEE-488 and RS232 compatible * Simultaneous displays with point and click operations * Sensor curve loading, modifying and saving * On-screen chart recorder * Auto PID tables * Data capture with full DDE support * On-line help 5. Pumping station * 2-stage, 16 CFM mechanical rotary-vane vacuum pump that can evacuate a volume of space from atmospheric pressure to nominally 10-3 mbar * Thermocouple vacuum gauge with analog readout * Bellows style vacuum valve * Stainless steel interface line * Vent/backfill valve * Oil mist eliminator The provisions and clauses in the RFQ are those in effect through FAC 97-04.
