sPHENIX is a new detector at RHIC.

Dear all,

Yesterday Abhay shared the following information from CAD:

News from C-AD and preparation for Run 25:

The RHIC bus short repair is progressing well.  However, after a power dip late last week that shut down the cryogenic system for several minutes, electrical tests in both the blue and yellow rings failed. This seems unrelated to the original blue short and is likely caused by moisture; drying of the leads took place over the weekend and hi-potting will be performed this morning.  As a precaution, welding the blue cryostats will be delayed until all issues are resolved.  The updated schedule has RHIC fully cold on May 25^th.  BLIP and NSRL operations continue.

Abhay also added:

We still don’t know the precise numbers for FY25 budgets. We are operating RHIC with last year’s guidance, until DOE tells us more precise numbers. In the meanwhile, President’s FY26 budget released over the weekend suggests a ~10% cut for the Office of Science, we do not know what it means for HEP and NP. Further, it is only the President’s Budget. Both The House and Senate will need to agree before we have an FY26 budget. 

Best
