[Dsg-ft] MVT Status

[Amrit Yegneswaran]

marc, 
if dave recommends different components for the system in EEL, how long do you guess the lead time to procure these components would be.

Hi Stephan, 

Can you please give a status update on the Pressure Systems program activities for the MVT and FT, from the detector owners point of view. 


As for DSG involvement; 

    * George Jacobs has already forwarded the gas supply P&I diagrams and a list of components to Dave Kashy. (3/22/17) 
    * I sent a start up list necessary components for the gas controls/monitoring system last week. (3/23/17) 





Additionally, will the MVT detectors need to be tested in any location, other than the EEL 124 clean room (For instance: EEL 125 which is the room right beside the clean room)? 

Finally, the DSG will need authorization to hook up any gas to these detectors from the system owner (Bob Miller) or the design authority (Dave Kashy), and authorization may take many weeks. Dave Kashy may be able to comment on the time table of pressure systems calculations, examinations, and tests. 


Regards, 

Marc

Hi Stephan, 


As mentioned in this morning teleconference, both the detectors have complete signatures on their respective Operational Safety Procedure documents for use in the EEL building. The EEL documents do not cover operation in Hall B. 

In addition to the OSP, JLab requires a pressure systems analysis to be conducted for all gas systems. The initial step is the naming of a system owner (Bob Miller) and a design authority (DA). Bob named Dave Kashy as the DA for the MVT and FVT. 

In preparation for the SVT/MVT integration and testing slated for this summer, as well as the installation of the FT in the hall (You mentioned July), it is important to begin the pressure systems analysis as soon as possible. Dave Kashy will need documentation for the MVT and FVT distribution systems in order to start the process. Per Bobs request in the meeting, please contact him directly. Aditionally, please add dsg-mvt at jlab.org as well as dsg-ft at jlab.org (for FT details) to those communications so that the DSG can be informed of the status. As the DA, Dave will inform us when we can flow gas for each respective detector. 

Regards,
