Wednesday September 24 through Friday September 26
On Monday I wrongly reported that Main Injector (MI) vacuum problems had caused Recycler troubles. The Recycler had problems, but it was with their vacuum readbacks whenever the MIVAC system was rebooted.
At 4 AM on Friday, Fermilab suffered a power glitch due to feeder 37. The Duty Electrician reported that four feeders went down. CHL and the Tevatron service buildings were two of the areas without power. Operations called in the High Voltage expert. Two cryo techs were also called in to recover the cryo system. By 6:30 AM, the High Voltage expert had the power system back up. The line break that caused the problem will be repaired later.
One of the Booster jobs was to install three new collimators. They have been installed and here are pictures showing two of the collimators in place.
