[Halla_running] update & shift cancel till Monday SWING

[KiJun Park]

Dear All,

Sorry for keep informing you a bad news.
Based on message from Arne, it seems they have more serious problems.
A short summary:
(1) CHL2->SCN->NorthLinac: The CHL2->SCN hardware is in working order.  
Analysis indicates the cause of these trips should be investigated carefully.
(2) CHL1->SCM->SouthLinac: failed pump down to 2K.  
Evidence is mounting that there is a likely physical problem with cold compressor
 #4 (CC4) in the SCM. 

Cryo is formulating plans this weekend which they will review with Ops on 
Monday morning to formulate a revised schedule.

I cancel all shifts (OWL/SAY/SWING) on Monday(Mar.30).

Sincerely,
Kijun(RC)
