Although we didn't have a Hall B meeting today due to Martin Luther King
holiday, I just want to give a brief update on what is going on with the
KPP run preparations:
Last week we had a very successful accelerator readiness review (ARR),
that cleared the way for bringing beam to Hall B in February for the KPP
run, and for the engineering/commissioning run in October/November of
The installation in the Hall is going very well. The forward detector
system w/o HTCC is fully installed. The temporary gas systems for the
drift chambers (Ar/CO2) and the HTCC (CO2) detector are being finalized
and should be operational by next week. The Torus magnet will be brought
back online by the end of next week at 50% of maximum current. The
installation of the CTOF in a temporary support structure is 90%
finished (see attachment) and should be completed on Tuesday (the
installation team is running double shifts!). The HTCC will be
transported to the Hall this week, and the SVT will be inserted into the
CTOF from upstream by the end of January. Finally, the beam line and the
carbon target will be installed before beam operation.
The software is ready for the KPP run analysis and will be tested with
cosmic rays in the detector system as soon as the drift chambers are at
HV and generate signals.
To all, a good week!
