[Hallb-engineering] PI1028 Alarms

[David Kashy]

Krister,

Please finish the cooling and start filling today.
Please let Andy Sandorfi know when the buffer dewar is filling and on 
cold return.

Also since I'm going to California tomorrow at 5am I'll need to hand off 
the pager, and since I'll be out of town this weekend I won't be able to 
take it back till Monday. Anyone up to cover me?


Thanks
Dave
