“…As shown, the coldhead itself is predicted to have a PV specific power of 14 WAV at 80 K, comparable to other coldheads developed at Lockheed Martin ATC. 5,6 Lockheed's best in-line, high- capacity designs are typically 11-12 W/W. The slightly lower efficiency of this pulse tube is due in part to the U-tube configuration, the small diameter of the transferline internal to the compressor, and to the smaller cooling capacity.…”

For a variety of space-science applications, such as gamma-ray spectroscopy, the introduction of cryogenic cooling via a cryocooler can greatly increase the potential science return by allowing the use of more sensitive and lower noise detectors. At the same tune, the performance benefits must be carefully weighed against the implementation cost, any possibility of degraded detector performance associated with the operation of the cryocooler, and the requirement to achieve long life. This paper describes the development, test, and performance of a novel new low-cost, lownoise, high-reliability pulse tube cooler, designed specifically for highly cost-constrained, longlife space missions.The developed cooler marries two technologies: a low-cost high-reliability linear compressor and drive electronics from the 1.75 W tactical Stirling cryocooler of DRS Infrared Technologies (formerly Texas Instruments), and an 80 K pulse tube developed specifically for the compressor by Lockheed Martin ATC. The successful new cooler achieves over 1.6 watts of cooling at 80 K at 23 W/W, and has the advantages of greatly reduced vibration at the coldtip and no life-limiting moving cold elements.To achieve maximum life and low vibration, the compressor incorporates flat flexure springs for piston support and uses two opposing pistons in a head-to-head configuration with linear drive motors. The pulse tube is a compact U-tube configuration for unproved integration and is mounted to the compressor in a split configuration with a transfer line.

“…The cooling power of 5 mW at the 3rd stage and 80 mW at the 2nd stage was measured in the PTC. Since the suitable space compressor had not been successfully developed, this J-T cycle used 4 He as the working medium for the open-loop experimental test and obtained the cooling performance of 1.4 mW@1.7 K [25]. Figure 7 shows the performance of the J-T cryocooler with different supply pressure.…”

The space 2 K cryogenic technology is one of the critical supporting technologies for deep-space explorations. With the development of space detectors, such as infrared and X-ray detectors, the demands for the space 2 K cryogenic technology have become much more urgent. Early space detection missions used superfluid helium cryostats (SHCs) to meet their requirements. However, cryostats have been gradually replaced by the 2 K mechanical cryocoolers due to the large volume, heavy weight, and short life of cryostats. Hybrid JouleThomson (J-T) cryocoolers are the best alternative to cryostats in the 2 K mechanical cryocoolers because of their relatively higher efficiency at 2 K. This paper provides an up-to-date review of space missions involving 2 K hybrid J-T cryocoolers and a summary on the key issues that need to be solved in the 2 K J-T cryocoolers.

“…With the emerging industry of cryoelectronics, HTS suppliers need a low cost, high efficient and long life cryocooler. Much effort has been invested in the production of such a cooler [1][2][3][4][5][6][7], involving both space and tactical cooler manufacturers. Space coolers have the advantage of long life, but the lack of experience in mass production and cost cutting make the cooler quite unattractive in price.…”

We have successfully developed and qualified a 5-Watt Stirling cryocooler that is suitable for commercial applications in the high temperature superconductor (HTS) wireless communication systems. The cooldown time to 77 K is less than 5 minutes (with 4 Watts heat load and a thermal mass of 1465 Joules). The cooler can provide a refrigeration capacity of ~5 Watt at 70 K. The qualification and test results of this cooler are discussed. FIGURE 1. A photograph of the B5000E Cooler.
