MICE CMPB Alain Blondel 1 August spokesperson remarks CMPB MICE NEWS

MICE CMPB Alain Blondel 1 August MAIN MESSAGES MICE is recovering from the major hickup (Project manager resignation) and associated collateral dammages (PSI solenoid, lapses of communication, delays in refurbishment of quads etc...) thanks to the dedication of many MICE and Ken Long and Chris Nelson in particular. -- Priority #1 is to ensure that full beam line is ready for step I data taking at the end of the christmas shutdown (20 January) -- It appears desirable and possible (though not certain at the moment) that beam provided by a simplified version of the beam line (target, Q1-Q3, B1, B2) could be operational in November together with a good fraction of detectors (CKOV, TOF, perhaps even the tracker) taking advantage of ISIS developments breaks in septembre and maintenance break on 4-8 November. -- this is a natural step in the debugging of the beam line and would allow major test of the part of the beam line that is installed in the ISIS vault (--> possible fixes in the Xmas shut down) -- calibration of pions/ISIS irradiation, a major unknown at the moment. -- shake-down of the detectors and DAQ, installation in the control room -- generally keeps the momentum rolling and avoids work pilup in february Meanwhile detectors will be integrated with Cosmics in R12 mezzanine Uncertainties concern target, PSI solenoid, controls and Hall installation; The rest of MICE is on schedule -->

MICE CMPB Alain Blondel 1 August FURTHER NEWS 1.Since March 25, Malcolm Ellis is keeping a MICE NEWS page. 2.MICE Installations/commissionning/operations group MICO is now operational. (last meeting on 26 July) 3. MICE is now an INFN recognized NTA (New Technologies for Accelerators) project: travel money from INFN and funds awarded by RAL end of year budget can be used. 4. EUROnu Design study proposal is very well ranked. 5. preparations for accelerator IA EU-proposal are underway with, for MICE -- access program to -- training program (students and postdocs???) -- work packages on RF cavities surface studies (R. Saviour at Liverpool), and 200 MHz power source (Montesinos at CERN)

MICE CMPB Alain Blondel 1 August Target (Sheffield; C. Booth and P. Smith) Target functioning reliably – 3.7 M actuations over 12 weeks. this is about what we expect from >1 year of operation of MICE Bearing wear considerably reduced with use of leaded bronze further studies to be done with Diamond-like Carbon aim to install in early november

MICE CMPB Alain Blondel 1 August Leaded bronze bearings after 1.5 M pulses <-- Brass bearing after x pulses

MICE CMPB Alain Blondel 1 August Dust at bottom of housing (after 1.5 M operations) Expect <1% of this to fall in ISIS vacuum pipe Is this acceptable to ISIS? proposal will be discussed with Steve Pin, writen up and sent to David Findlay for approval. Alternative – DLC (Diamond-like carbon) coated shaft & bearings received new shafts from Oxford. Will send off shaft & bearings for commercial coating Test will take at least 3 weeks (2 M pulses) once received. ready in october?

MICE CMPB Alain Blondel 1 August Tracker -- 9 tracker stations have been completed by now. (5 for one tracker) Still a few problems with the light validation bench. No dead channels seen and a few only have apparently a little less light. Main and urgent issues the need for specification of path of the low voltage cables and need to define the fire alarm system to have permission take the spares from D0. Fermilab will go ahead with a design using the VESDA system. Spectrometer solenoid on track and progressing well (See M. Zisman's talk) EXPECTED delivery of solenoid I at FNAL end december 2007 and at RAL 2 month later (late february) after magnetic measurements. ==> start step II in April. NB these are typical technical coordinator actions we stumble on those at the moment

MICE CMPB Alain Blondel 1 August PSI solenoid successful repair with help of Walter Gloor one of the tie-rods to the cold mass had also fallen off. Magnet is actually in good condition. Plan is to finish off repairs at front of solenoid, MLI insulation and replace the cover. Next is cold test and Linde refrigerator will be needed, but there is a legal issue as the certification of the whole assembly by Linde is missing (not just parts). next is collecting cold box etc... timescale is September mid October the latest. The position in the hall for cold testing is on the south side of the hall It does not interfere with possible test or installation of detectors on the beam line. Action keep pushing for the Linde contract to be signed. (Tom Bradshaw)

MICE CMPB Alain Blondel 1 August CKOV Parts of the first (of 2) detector have arrived at RAL (+ L.Cremaldi and David) Customs overcome with 'magic words' – not totally smooth, but getting there! Aerogel, box, mirrors (From USA) and phototubes (from Trieste) will be ready in september second CKOV could be there for November. Support being build under supervision by W. Lau (Oxford) TOF0/1 being built in Milano, delivery at RAL 1st November with laser calibration system DAQ delivered by JSGraulich and VVerguilov. All installed in R12. --> DAQ workshop July: -- interface with software and data storage -- transmission of knowledge to tracker group (James Leaver et al) -- empahsized need for Controls and Monitoring task (Daresbury) to begin (Target control, beam magnets, safety)
