EVERYBODY is trying hard to be on time according to end-of-shutdown/ISIS run
on 21 January/4 Feb
-- ISIS has two major problems:
ISIS dipole 2 needs changing,
ISIS target has problems
-- 21 January: ISIS must be closed (there may be a small delay in this date)
21-jan--> 4 Feb running in period
We have requested three times 2-3 shifts with MICE control: early, mid, late in this
period + any available nights.
It is still possible to install reliably a detector that would arrive at RAL
in the early part of that period DSA or even in vault (CKOV, TOF0, MBLM)
5 Feb--> production run of ISIS until 13 March
Installation opportunities in the DSA will be limited and random
0.- (basic radiation levels - no target in) - doesn't need any specific shifts
1. - 2x8-hour shifts for target tests at the middle of the startup period - to establish target running requirements.
- target position, loss volts, isis activation
- increase dip to 0.05V.
- radiation levels ~ MICE hall etc.
2. - 3x 8-hour shifts for beamline installation/commissioning work @ 0.05V
- 'flushing through': first functional tests where entry synch/DSA poss. to fix
- radiation levels~ MICE hall etc.
- measure of *early* rates
- standardisation checks.
Plan to proceed
: 1shift negatives w/o proton absorber
: 1shift negatives with proton absorber
: 1 shift positives with proton absorber.
3. - 2x 8-hour shifts for target tests at the end of the start up period
- continued target shifts if problems.
- or to aim to above 0.05V, measure stability, loss, activiation etc, MICE rad. levels.
4. Any available night shifts
Main conclusions from MICO any specific shifts
++ beam line installation
2 major hickups, scrambling to recover:
-- ISIS personnel not available for upstream beamline work (alignment etc) -- New Target stand not ready
++ MICE detectors
-- Ckov ready to install (stands?) before 20 Jan.
-- TOF0 to arrive last week of January (preferred) or first week of Feb.
-- Mice BeamLineMonitor from Fermilab will arrive for step II. An array of scintillator is being prepared at ICL for the MBLM1.
==> we would like to know more about this.
-- TOF1, KL to arrive second half of February (stand in absence of Spectrometer solenoid?)
-- Jean S. Graulich and Paul Soler has been approached to provide scintillator to measure integrated particle rate at ‘tof0 and tof1’ until these detectors have arrrived. (These scintillators will remain useful)
-- tracker: cryomodules have been repaired. Could be shipped to RAL by end January. Tracker operational first half of February. (meeting Friday 11 to decide: cosmic test or put in beamline? Should be able to do either depending on circumstances
Run Plan any specific shifts
Determine sequence of events to running in the beam line
Flexibility will be required and order of events may change
Plan does include radiation monitoring (2 monitors needed)
and radiation surveys at four specific configurations to determine possibility of
Hall construction while taking data
(tracker TOF1,2 KL installations, Mag. Shielding, Spectro Solenoid)
Pion beam line dipoles, quads, DK solenoid, proton absorber in/out, + and -
Vary momentum to measure part. prod.
If possible muon beam and vary optics towards end of period
Action: produce descriptive note.
Controls and monitoring: no report
Running MICE safely any specific shifts
Regular safety-coordination meetings are run by David Findlay with relevant MICE
Management. Aim is to ensure safe operation of MICE
Richard Apsimon is the MICE person responsible for safety matters
While MICE is operated the MICE operation Managers will be in charge by delegation of R. Apsimon.
David Findlay30 November 2007
MICE run and MOMs always be able to have access to equipment in R5.2 associated with ISIS operations.
Important aspects of running MICE always be able to have access to equipment in R5.2 associated with ISIS operations.
The Technical Coordinator/Project Manager is responsible for the safe implementation of the experiment and for its safe operation.
Day-to-day responsibility for safety during the build phase of the experiment is delegated to the Hall Manager and Principal contractor.
During running, the safe operation of the experiment is delegated to the MICE Operations Manager(MOM) .
For each MICE step a set of safety reviews will be organized by the MICE project manager, before installation (safety design review), before commissioning (authorization to operate) and before regular operation.
The critical subsystems of MICE will be reviewed either collectively or one by one as will be seen fit by the MICE project manager in agreement with the spokesperson and in presence of one or several designated ISIS representatives as required.
A fool-proof operations manual, including safety aspects, will have to be ready for each MICE subsystem before regular operation.
The documentation is the responsibility of each MICE subsystem.
MEETING CALENDAR always be able to have access to equipment in R5.2 associated with ISIS operations.
Next Scheduled MICO meeting Thursday 24 January:
Next collaboration meeting:
Sunday 10- Wed 13 February 2008
Registration page will be posted imminently. Please register.
parallel meetings on Sunday: tracker PID, software, beam line
Plenary monday morning in auditorium with Womersley
Parallel meeting in the afternoon (software--> analysis)
Collaboration dinner monday evening
Plenary on Tuesday morning and Wednesday morning
EB on Wednesday afternoon.
parallel in R12 R13 or plenary in R12+13 monday aft to wedn. morning.
MICE will be running-in ==> meeting at RAL,
Accomodation has been booked on site at the Ridgeway House(20) and R70(10).
Because ISIS will be running there will be food at the RAL in the evening,
entertainement in the evening will be conditional to having a car or friends with one.
