News from the MOM¶
The first scheduled Machine Physics beam period for MICE on Tuesday evening was cancelled as ISIS
was still bringing up the machine.
- MICE and ISIS suffered a complete power cut last week on Tuesday. We lost power to the MICE Hall,
the rack room, and the MLCR at about noon. The reason for this outage is not yet known but is under
investigation. The DS was powered at 200A - it lost all He and began to warm up when the power cut out.
We refilled the He buffer, and the DS RAL team brought the magnet back to operational and it was turned
on again Friday morning. The single station tracker cryostat and electronics were also ON. The cryostat
lost the vac pumps but the automatic valve kicked in as designed when we lost power so recovery was
complete within the day. All racks, computers, servers, and IOCs in the Hall and target vac rack area
were recovered, rebooted, and regained full functionality by 7pm Tuesday. This includes access to the DS
mimics to aid in the magnet recovery.
- MICE took beam on Friday evening during our second scheduled shift. ISIS was up and running, and MICE
was ready. We successfully ran in the target with the adjusted lower limit on the frame and the
now-standard beam bump in ISIS. We are operating with a 2V loss limit. In order to increase this, we
will need to schedule an activation run during a Machine Physics period using the beam bump as all previous
studies were done with ISIS in the non-beam-bump configuration. Even with the limit, when we ran with a
272 MeV/c pion Reference Run beam, we were getting significant numbers of particle triggers with ~1000 in
TOF0 and ~450 in TOF1 when operating under the 2V limit. During running, we were also able to see triggers
in the single station tracker system at the same rate as in TOF1 (which was generating the trigger).
- The Tracker Controls rack was installed in the Hall last week with a prototype controls system that
will be used during the single station tracker test. The Tracker team continues to assemble at RAL with the
arrival of the Fermilab team on Saturday. Work continues on the tracker DAQ with a focus on timing in all
of the signals with the live time of the tracker electronics.
- A new Shifter Training regime has been instituted in the last week - contact the MOM for details if you
are scheduled to take any shifts in the near future. Even if you have previously been a shifter, you must
have your training assessed and be brought into the new system.
- MICE will be taking beam this week Tuesday through Sunday for the tracker single station, Software tests,
data for global tracking analysis, and Run Control integration.
- Stewart Greenall (MICE Hall Manager) is clearing out unnecessary equipment/cabinets/shipping crates/etc.
from the MICE Hall. If you (CKOV group, TOF group, etc) have ANYTHING in the Hall that you want to stay there,
email Stewart (email@example.com).
Yagmur Torun is to be promoted to associate professor with tenure at IIT.
Dan Kaplan believes he the first person in the world to get tenure based on muon-cooling R&D.
