[Dsg-halla_gem] [EXTERNAL] BigBite GEM gas monitoring Channel 03

[Marc Mcmullen]

Hi Holly,

I’m just checking to make sure the BB is safe for me to do testing. During testing the gas supply will be subject for shut off on multiple channels. Please let me know if this is ok.

Marc

Hi Marc,

The target group needs to do some tests before we can sweep the hall. They thought that they will be done by 8:30 but it’s taking longer. So, I have doubt that we will be in controlled access by 10. Right now, 10:30 pm seems more reasonable. Please plan accordingly. I’ll let you know if anything changes. Sorry for the inconvenience.

Best regards,
Provakar

Hi Marc,

I will put you on the schedule for 10 am tomorrow. RadCon should be done with the survey by then but I am not 100% certain. So, you may have to wait for a few minutes before you can go in, please plan accordingly.

Best regards,
Provakar

Hi Marc,

I am still waiting on RadCon to let me know around what time they will be able to survey the hall. Once I know that I will be able to give you a proper time frame.

Do you have a preference of time? Also, how long do you expect to be in the hall?

Best regards,
Provakar

Hi Marc,



There is an opening tomorrow. I cc Provakar above as he is the current RC, and he can let you know when you can go in.

Hi Jack,



The next time there is a scheduled opening I need to check out Ch.03 on the BigBite gas distribution.



Since 10/27 the reading has a band of about 30 sccm. Compared to Ch.01, the band is closer to 1 sccm (normal).



We will use that time to determine where the problem is along the flow path.



Regards,
Marc
