[Halld] End of run maintenance

[Timothy Whitlatch]

Hi All,



As you probably know, beam is scheduled to be shut off April 15.

I spoke with Jonathan creel this morning, he would like to start shutting down the Hall D refrigerator on April 17th in preparation for parking at 80K for 2 months to do maintenance to their systems.


In addition, I spoke with Paul Powers this morning and they wish to do maintenance on the Hall D transformers on April 22. This would mean all power to the counting house and Hall will be down about 6 hours. The UPS should be able to supply power throughout this period for any critical or controls systems that are on it.


Regards,


Tim
