- Description:
- The University is soliciting prospective proponents to submit proposals for a Helium Gas Cryogenic Cooling System.The Cryogenic Cooling System will be used to cool a laser amplifier. The laser crystals, which need to be cooled to
70 K, are mounted on cold fingers located in a vacuum chamber, whichitself needs to operate at
70 K. The low-temperature helium gas from the proposed Cryogenic Cooling System runs through the cold fingers. The thermal load generated by the laser crystals is 800 W, which can be supported by a solution consisting of either one or two helium cryogenic coolers. Thehelium transfer line should not cause large vibration to the cold finger. The stability of the temperature should be less than 10 K. The coolers should operate without using liquid nitrogen. The instrument must operate for 24 consecutive hours; 7 days per week (24/7), outside of planned shutdowns forannual maintenance.In the cooling system, helium gas is cooled at the cold head to
70 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 finally then cooled downagain for cycling.Mandatory Requirements:1.Helium Gas Cryogenic Cooling System 1.1 Proposed solution must be composed of one of the following: One (1) unit with a maximum cooling power using circulated helium gas of 800 W or higher at 70 K; or Two (2) units, each with a maximum cooling power using... - Documents:
