[Esr-users] blockage in Hall C coll return- update

[Paul Brindza]

Greetings

Measurements of the cold return pressures in Hall C along the transfer 
lines to the SHMS indicate that the transfer lines are OK.
Pressure readings( see below) are very close to previous measurements 
made during investigation of Anaconda pressure drop.
Some SHMS Magnets are at considerably higher pressure than the transfer 
line.
Checking cold return valves for possible blockage will start in a few 
minutes.

Cheers

Paul
