Refrigeration at 2 K and below has become the new standard in cryogenically cooled particle accelerators. Up to four cryogenic turbo compressors need to be operated in series in order to reach the required sub-atmospheric helium bath pressure. Such highly developed systems shall operate at high reliability not interrupting the entire research facility. Linde Kryotechnik successfully supplied...
In order to effectively characterize the performance of the cryo-viscous compressor (CVC) prototype, supercritical helium (SCHe) was required in order to mimic the conditions that the CVC would see in its installation site at ITER. Given the specific requirements for SCHe (2.0 g/s, 4.5 K, and 3.0 bara), a collaboration between US ITER and the Spallation Neutron Source Research Accelerator...
To effectively process the mixed exhaust from the regeneration of the ITER torus cryopumps, a cryo-viscous compressor (CVC) prototype has been designed, fabricated, and subjected to successful performance testing. This testing, which was performed at the Spallation Neutron Source Cryogenic Test Facility, involved cooling a set of twenty-four 5-cm diameter, 1.27-m long stainless steel tubes...
The linear compressor for cryocoolers possesses the advantages of long-life operation, high efficiency, low vibration and compact structure. It is significant to study the match mechanisms between the compressor and the cold head, which determines the working efficiency of the cryocooler. However, the output characteristics of linear compressor are complicated since it is affected by many...
