The Spectrometer Solenoid review

documentation http://indico.cern.ch/conferenceDisplay.py?confId=110250reviewers:Amalia Ballarino – CERN ,Elwyn Baynham – ITER, Tom Bradshaw – STFC, Mike Courthold – STFC, Vladimir Kashikhin – Fermilab, Robert Sanders – Fermilab and Pasquale Fabbricatore acting as chair –INFN-Genova).

MICE collaboration members attended the review Alain Blondel– UNi Geneva, Alan Bross – FERMILAB Andy Nichols – SFTC

Review began 27 October (where repair plan was described by Steve Virostek) intermediate meetings 11 Nov and 29 Nov. Final report on 14 December

MICE note 335 has all information about the review (incl. proposal for repair plan)

Main conclusions:

1. Review committee acknowledges additional staff put by LBNL to magnet2. needs to intensify these contributions3. The review committee does not recommend moving forward with repair plan

but before doing soA-- to complete the thermal model calculationsB– to study an effective protection of the magnets and particularly of the leads This last point is seen as quite critical

Now SS team will study the recommendations of the panel, evaluate consequencesnot quite ready yet. Main issue is calculation of needs concerning quench protection1. time to execute additional delay of a few months.2. costs (almost 1M$ cost-to-complete for the two spectrometers)

According to original plan (including magnetic measts) we would expect delivery at RAL of SS1 in Oct11 and SS2 in Mar12

a delay of a few more months to complete/approve the plan

Berkeley team has proposed to execute already a certain amount work not.inconsistent with review recommendations to improve schedule

The Spectrometer Solenoid review


MOM 2011

we have restarted MOMs on 17 January (needed when ISIS is running)

goals for 2011 : commission new target (Champion: target group) increase beam loss limit (Champion: target group) commission EMR (June-August) (Champion: EMR group) complement Step I measurements if necessary (Champion: Apollonio) TOF and KL calibrations (Champion Maurizio)

See preliminary plan of activities data taking to be finalized at CM29 with input from installation team


ISIS running periods, MICE CM29/30/31 and MOM Rota proposed MICE runs in 2011 to be finalized at CM29

First semester

Second semester


Coupling coils

review took place in Mid december. First coil has been wound at Qi Huan

Serious concerns about delays at HITfor testing cryostat.

milestones given in June 2010:Complete winding of MuCool coil on mandrel ICST 9/30/10 finished in december 2010 – not bad. Complete testing of large test coil in ICST test facility ICST 11/30/10 delayed till at least September 2011….

The next occasion: visit of Derun Li in February 2011. At the same time, US team now investigating/developing a back-up plan for the construction/test/assembly of the coupling coils.


MICE overall magnet coordination

It has been felt necessary (since May 2010) to have an overall coordinationof the MICE magnets.

Team will be led by Roy Preece and Mike Courthold. They have agreed.


By Next Meeting

• Develop complete understanding of Step 1 data– continue efforts to study increased intensity/beam loss regime

– produce first MICE paper ! (NB need to specify content more precisely)

• Simulations of measurements needed for Steps 3-4• Resolve external field issue for Step 6 solenoid mode• Fully develop magnetic measurement needs and plan

– in writing!

• Review and approve spectrometer solenoid repair plan• Complete, review, and approve CC cryostat design• Assess progress of CC cold mass fab + HIT test facility• Prepare test plan for RF cavities• Monitor progress on EMR fabrication and impact on infrastructure

From Mike Zisman’s wrap up.
