Detailed Description
This job is to maintain the liquid helium target refrigerator for Minerva. The maintenance is done by a factory technician who brings all of the parts with him. We will do contractor training early on the morning at 7:30-8 AM. Then we need to get the specific training for him to be escorted into the Minos cavern so he can do the work. I will act as his escort. I estimate it will take him 4 hours or so to do the work. I have to arrange for the company to provide the tech so I'm going to ask for him at any day this week.
