[Halld] PSS testing

[Alexander Somov]

Hi Tim,

Will the Hall will be reopening today ?
Also, could you confirm if the light sensors inside the dark room were recalibrated? The readings are currently between 0.45 and 0.49, whereas they were around 0.25 yesterday. I’m hoping there isn’t any light in the dark room.

Thanks,
                Sasha

We just found out that the hall is closing now for PSS testing for a few hours.

Sorry for the late notice
