Hi,

The gas flow chassis was moved last month to the SBS rack.  We have printed holding clamps for the in-line filters. The fittings for the SBS filters have arrived and will be installed.

Both the SBS and BB will have the gas filters installed at the same time since they are on the same rack now and then DSG will hook up the low pressure side detector gas lines for everything.  (Gas Flow Sensor -> Filter -> detector)

George Jacobs (DSG) will coordinate with Hall A when the SBS supply needs to be shutdown and connected via "T" fitting to supply the BB regulator. This will be done by Hall A engineering at the appropriate time.

Finally, I will move the BB monitoring cables from the old rack to the SBS rack, connect and get the monitoring started.

Regards,
Marc
