D-Zero Collider Detector CC Cooldown/Fill and Overview
The cooldown will be immediately preceded by two trial pump downs; the insulating vacuum and the detector volume. The insulating vacuum must be established to a level below 10{sup -4} MM Hg to minimize the conduction heat load. The detector, aka cryostat, vacuum pump down must be able to reproduce the ultimate and rate-of-rise (ROR) values demonstrated in the clean room. It is anticipated, barring newly generated problems, it will take a few days to accomplish both of these tasks once the construction is complete, even though there has been incidental scavenger vacuum pumping. When the leak detectors are put away, the real Pump and Purge (P&P) begins.
