[PEPPo] Daily Report 13 June 2012

[fanchini at jlab.org]

Yesterday evening after taking beam for beam background measurements we
took some runs to try to degauss the analysing magnet contribution.

At the end of these studies we switched to production mode changing the
momentum to 4.2Mev/c till the morning.

During the day we were able to take some background data for the
integrated mode and, at the same time, they continue the investigation on
the magnet power supplies. On this side there was a major change in order
to establish a better common ground.

We restarted the swing shift trying to restore the running condition of
yesterday. This time with same current of yesterday in PEPPo FC and having
PMT rates close to yesterday's run, we noticed a TS1 rate drop. Signals
and timing spectra seem reasonable. A possible explanation is the new
spectrometer current stability reached with the intervention of this
afternoon.
We are continuing the established plan, useful also for further
investigations.
