Hi Marc,

We will begin to decrease the gas flow now back to nominal.

Hi Marc,

Lost track of time a little bit. I changed the flow meters for the GEM gas panel in TEDF just a minute ago. Currently channels 1-4 are all about 350 cc/min. Whereas channels 6 and 8 are about 500 cc/min. Let me know once the hour or so is up and you are ready to have them moved back down.

Best,
Ezekiel

Hi Marc,

We are coordinating to do the high flow test on the GEMs this afternoon. What duration would be desirable for this test? Minutes? Hours?

Thanks,
Holly
