for the loop back test power permit is not needed. We can do it now as we are not running rf in NL. We will continue the troubleshooting with the klystron power once available. First step is to determining if it is originating inside the chassis

Is there a PTW for this job?

Task lists 4 days to complete. Is that right?

We won't be able to check NL Gangphase until after all YB swap is completed and beam can be transported to 1R dumplette, through the NL. Not a problem, but something we need to make sure Ops is aware of.
