Hi Morgan,

The instrumentation is disconnected from the panel.

Hi Morgan,

As far as the instruments are concerned (4 pressure sensors = disconnect at gas panel, 2 solenoids = unplug from 120 AC Relays) disconnect on panel end.

Also, ensure the power strip on the bottom shelf of the table is off. This will remove any power to the panel components.

Hey Bob,

Yeah, they just called me and said everything is still connected.  We’ll get back to it after the detector install.

Regards,
Morgan

Hi Denny,

When the gas panel is moved to the Hall, please use a truck.  The bubblers will not survive the impacts from a forklift.

Thanks,

Hi Denny,

When do you expect to install the gas panel next to ALERT?

Hi Marc,

When do you expect the gas panel to be functional in the Hall?

Thanks,

Hi Bob,

 As we discussed yesterday, would it be possible to start purging the Hall B gas line? As per the current schedule, ALERT detector will be at the beam level on Thursday. It's probably a good point to start purging then.

In case the installation is taking longer we could stop purging over the weekend and leave 2 atmospheric pressure in the tube.

 What do you think?

Have a nice day,
