[Dsg-mvt] Fwd: Number of premix bottles

[George Jacobs]

Hi Maxime, 

There are no FTT bottles. The PR was never signed. I will get back to you with a count of what remains asap. 

The MVT mixing system outputs signals to EPICS, argon flow, C4H10 flow, CF4 flow, etc. These EPICS values can have alarms associated with them.

Dear George, 

Can you remind me the number of premix bottles left for MVT? Can you 
include in the FTT bottles? Indeed, since they are not using them 
because already installed in the Hall, we have been allowed to use them. 

Also for the operationnal manual, we would need to know the measurement 
available from the mixing system for monitoring and interlock 
definition. For instance, will we have access separately to the flow of 
Argon and isobutane to make sure the ratio is correct between the two 
components? 

Kind regards, 

Maxime
