[Esr-users] question: Hall C liquefaction load on ESR

[Joe D. Wilson, Jr]

Hello to All,

At about 0845 on 12Mar18, a quick test identified a Hall C liquefaction load
on ESR of about 10 g/s. The warm return the valve configuration was changed
one hall at time. Therefore, the extra loading of ESR disallows cooling of
Hall B and filling the ESR dewar.

Is there an issue (past or present) within Hall C? Is there an issue (past
or present) within Hall C? For example, it is conceivable that a past
contamination may cause a problem today.

 

Thanks!
