Abstract

The present RHIC cryogenic process control system is a hybrid of centralized and distributed processing. The setup marries together a centralized sub-system that was designed, installed, and in operation since 1984 with six identical distributed sub-systems, whose installation began in 1996 and will be completed in 1998. For the RHIC First Sextant Test, which took place from January 21, 1997 to March 5, 1997, it was necessary to have two new distributed cryogenic control sub-systems installed and tested.

During the First Sextant Test, gold ions were successfully injected into the superconducting collider at the 6 o’clock region, where they then traveled down Sextant 4/5, and hit a beam stop at the 4 o’clock region (Figure 1). The 6 o’clock region, 4 o’clock region, and Sextant 4/5 are the locations where the two new distributed sub-systems were installed and tested. The thrust of this paper is to discuss these new installations and the overall cryogenic control system performance during the First Sextant Test.
