[Esr-users] Cooldown of Hall C target

[Joe D. Wilson, Jr]

Hello,

As of 0800 on 23Jan18 (today), it was announced at MCC that the Hall C 15K target cooldown may occur on late afternoon today, pending information update. Of course, the Cryogenics Department appreciates any updates with respect to any anticipated changes to the ESR loads.

Thanks!

Hi Chris and Joe,

 

I discovered that my phone is no longer sending mails so I apologize for not sending notice to you that Hall C would like to cool down their target in the AM on 1/24. We anticipate that this will take about 4 hours to get onto the cold return and another 4 hours to condense the H2/D2.

 

Thanks
