MICE CM16 Goals Alain Blondel 8 October 2006 3

Competition is active! better beta beams:

use higher Q isotopes (C.Rubbia) instead of He or Ne (Q~3 MeV)

8B --> 8Be e+ e

or 8Li --> 8Be e-

anti- e

+ New production scheme would allow higherintensities

--> altogether higher energy and higher rates for the same storage ring rigidity

-- exact structure of each study to be decided by proponents

-- Regional Oversight Committees will possibly converge to a single international committee for a future precision neutrino facility

8MICE CM16 Goals Alain Blondel 8 October 2006

EP2010:

« pursue an internationally coordinated, staged program in neutrino physics »

CERN-SG: Studies of the scientific case for future neutrino facilities and the R&D into associated technologies are required tobe in a position to define the optimal neutrino programmebased on the information available in around 2012; Council will play an active role in promoting a coordinated Europeanparticipation in a global neutrino programme.

Towards a high-intensity neutrino programme

STEP I: 15 September 2007 = 340 days to data taking!

STEP II: soon after

PHASE I

MAIN GOAL of meeting:

Understand where we stand in our preparations for Steps I and II (and III).

More Generally: monitor status of experiment, make necessary decisions to move forward, identify issues that require action

11MICE CM16 Goals Alain Blondel 8 October 2006

EXPECTED RESULTS --I-- (from CM15 to CM16)

BEAM LINE-- target system: solution for heating of linear mechanism, test of system progress of first beam test (expected end of october 2006)

-- status of beam solenoid -- beam line construction

-- optics: full coverage of emittances and momenta? correction and tuning systems; collimators and controls

-- diffuser size & mechanism

12MICE CM16 Goals Alain Blondel 8 October 2006

EXPECTED RESULTS --II-- (from CM15 to CM16)

DETECTORS-- results of test beams at Frascati and Fermilab-- upstream Cherenkov and TOF0/1 review at the end of the meeting

-- tracker (first plane and QA?)

-- downstream shield/TOF2/EMcal size! -- scraping issue -- funding and schedule issue!

DAQ and controls -- workshop in Daresbury in September -- overview of system and proposal

13MICE CM16 Goals Alain Blondel 8 October 2006

TOF

Ennoying questions: TOF2 said to be mid-2008. Can this be brought forward? what will happen with x-ray radiation when we run with RF?

Issue: particles crossing material in the downstream end of the spectrometerthis is a beam of 100-300 MeV/c, all generated with 4T field in spectrometer. How about the size of the hole in the shielding

Preparations of TOF0 test on-going (Milano-Pavia)double layer allows measurement of resolution, meast is of this is the main aim of the test

14MICE CM16 Goals Alain Blondel 8 October 2006

EXPECTED RESULTS --III-- (from CM15 to CM16)

ANALYSIS -- run plan (time is expensive and people are few) -- time measurement discussion-- scraping, emittance propagation etc.. -- associated questions: time definition in MICE (master clock?)

SOFTWARE-- launching MICE data Challenge?-- continuous improvements (last time was spectacular)

15MICE CM16 Goals Alain Blondel 8 October 2006

EXPECTED RESULTS --IV-- (from CM15 to CM16)

INFRASTRUCTURE-- general experiment infrastructure-- MICE-folks becoming official users at RAL-- HAZOP and safety report

PHASE 2-- UK bid under review -- LH2 R&D -- Coupling coil (First Harbin report in a collaboration meeting!) -- RF cavity progress at Fermilab-- power source progress-- RFCC and absorbers

PHASE 3-- how does MANX match to MICE?
