Description:
The University is soliciting prospective proponents to submit proposals for a Helium Gas Cryogenic Cooling System.The Helium Gas Cryogenic Cooling System will be used to cool a laser amplifier. The laser crystals, which need to be cooled to ~90 K, are mounted on cold fingers located in a vacuum chamber, which itself needs to operate at ~ 90 K. The low-temperature helium gas from the proposed Helium Gas Cryogenic Cooling System runs through the cold fingers. The thermal load generated by the laser crystals is 600 W. The helium transfer line should not cause large vibration to the cold finger. The stability of the temperature should be less than 10 K. The coolers must operate without using liquid nitrogen. The instrument must operate for 24 consecutive hours; 7 days per week (24/7), outside of planned shutdowns for annual maintenance.In the cooling system, helium gas is cooled at the cold head to ~90 K and transferred into the helium cycling pump for pressurization. The low temperature helium gas will then be outputted onto the laser crystals for one-way cooling. The returned helium is then cooled down again for cycling.The cold finger on which the crystals are mounted are supplied by the University. The pressure drop is 15 to 30 kPa. The University will also be supplying the cryostat vacuum chamber. The interfaces for the helium transfer line to the cold heads is UHV Flange. Mandatory Requirements:1. Helium Gas Cryogenic Cooling System 1.1 Proposed solution must be composed of...
