[Dsg-rtpc] [New Logentry] Pre-Mix gas bottle empty

[Carlos Ayerbe Gayoso]

Thank you!

Sebastian pointed out that the bottle indicates 21% CO2 (the other indicates 19%). I guess that although they are within the range provided by the company, Sebastian would encourage to have the bottles the most similar possible,

Hi Carlos,

I will install a full bottle of premix tomorrow and train the Jack Segal to change the bottles during the shut down.

When the experiment stops tomorrow, please reduce the premix flow to 50 ccm.

Regards,

Bob

In order to prepare for the shut down, and as was agreed in the morning Hall B meeting, we plan to run pre-mix gas a very low flow, with two bottles. But one of then is totally empty. Sebastian swap the bottle with the new one (it is at 1700 psi).

Deuterium is running low, BUT maybe we can run until the end of the production (tomorrow).
