MOM Report
(Pavel Snopok, Andy Nichols)
2010/11/18
VC
Actions/Milestones
• Andy Nichols is compiling a list of
milestones/activities
• Please help him populate the list with
actions/deadlines
• New MICE schedule is being prepared
2
Targetry
• Refurbishment of T2 complete
• Soak test and inspection regimen:
– Started 10Nov10;
• New DAQ and controls start of soak test
• Excellent resolution on hold position, BCD, etc.
• Trend in BCD and acceleration observed 12Nov10 so:
– Stopped activation to prepare for first inspection 16Nov10
• Magnetic re-design initated;
– Concept for new coil-winding design agreed (08Nov10)
• Specification agreed
– Magnetic axis tolerance 25 microns to match mechanical tolerance
– Permanent magnet dimensions under review
• Visit to vendor next step;
• Then review substrate, material, and possible vendors
3
Cryosystem
• Quench detector is back to RAL
• Buffer tank leak has not been fixed, epoxy
does not work, need alternative solution (or
wait until helium is used up)
• LH2 system pressure-tested and certified
4
MICE Hall
• North mezzanine rack extension underway.
• Need rack extension along East wall for diffuser control, tracker
readout, etc.
• New shape RFCC raises real estate concerns.
• Substation upgrade is being planned (March = no power to
MICE for three weeks), please let us know what equipment
needs to be independently powered.
• DSA/ISIS: with the start of the March 2011 ISIS user run, the
DSA effectively becomes part of the ISIS synchrotron and
interventions will only be possible at scheduled shutdowns.
Please let us know if your equipment can be maintained
remotely while running and if not, what work is required to
make it so.
• Air: MICE hall instrument-air supply was turned off at some
point in the past, small air compressor was put into use and
failed eventually, now instrument-air supply is restored.
5
PPS
• All hardware installed, ready for certification.
• John Alexander is to visit RAL on November 22
to start commissioning.
• Should take approximately three weeks.
• After that ISIS knows that PPS is up and
running.
6
Online
• miceonrec01/02 got new dual head video cards.
• Dual head monitors set up = more screen real
estate.
• KVM switch to handle dual monitors has been
installed (kudos to Henry), should get a separate
shelf in the rack for safety reasons.
• EPICS: Pierrick devised a scheme to get fast
access to monitoring (with a fixed IP). Ask him if
you need to know how.
• Polarity monitors installed
7
Diffuser
• New materials ordered (tungsten, brass).
• Parts to be send to Oxford in ~3 weeks.
• Magnetic parts are being replaced with
nonmagnetic.
• Redesign is underway for parts showing too
much friction.
8
Spectrometer Solenoid
• First round of SS review held on Oct 27
(http://indico.cern.ch/categoryDisplay.py?categId=1229 ).
• Reviewers gathered to formulate response to
the SS team.
• Feedback should be prepared by Dec 1.
• RFCC review: Dec 9.
9
AFC
• Coil winding about to start, deadline March
2011.
• Instrumentation list issue: more temperature
sensors might be required (both in cold mass
and HTS/LTS).
• Last Thursday – meeting with Tesla:
– thermal analysis around the turret,
– power suppy + quench detector specification.
10
Detectors
• TOFs: need re-survey + laser calibration is under
discussion.
• Tracker: readout – Oct, data – Nov, system safe – Dec.
• EMR: delivery scheduled for mid-2011, detector grows
in size/weight.
• KL: Ludovico Tortora visits RAL to discuss modifications
to KL trolley.
• CKOV: Lucien Cremaldi and David Sanders visited RAL in
October for wellness tests, some results are on elog:
