OPERATION
The ATLAS accelerator is a product of staged construction beginning in 1978. It serves as a national user facility for accelerating heavy ions at energies in the vicinity of the Coulomb barrier. The accelerator is divided into 3 sections with a refrigerator cooling each section through an interconnected forced flow distribution system. ATLAS acquired a CTI model 2800 from Lawrence Livermore...

OPERATION
This test facility at CEA Grenoble mainly consists of an helium refrigerator whose flexible operation permits various types of experiments or test benches to be coupled to it. This presentation first introduces the qualification of the performances of our helium refrigerator, able to cover a wide range of temperature, from 1.5K to 4.5K. Then we describe through several experiments successively...

OPERATION
The End Station Refrigerator (ESR) at Jefferson Lab (JLab) supports three experimental halls. The refrigerator for the ESR, a CTI 1500 W 4.5-K refrigerator designed in the late 1970’s, is capable of supporting a 1250 W target load at 15 K (simultaneously with a 1100 W 4.5-K refrigeration load). This plant has been routinely supporting 15-K target loads, as well as 4.5-K magnet loads, since...

OPERATION
Two helium refrigerators, each rated for 3.5KW at 20K, are used at NASA’s Johnson Space Center (JSC) to provide cryo-pumping within two large thermal-vacuum chambers. These refrigerators were originally commissioned in 1996. Equipment refurbishment and upgrades of the controls of these refrigerators were recently completed. This paper describes some of the mechanical and control issues that...

OPERATION
SPIRAL2 is a rare isotope accelerator which will based at GANIL, it is dedicated for the production of high intensity radioactive beams (E=40Mev, I=5mA). The driver of SPIRAL2 is a Linac, it uses bulk niobium superconducting RF cavities cooled with liquid helium. The cryogenic transfer line of the Linac is composed of about 20 valves boxes which su[[ly two types of helium cryogenic lines: The...
