MICE COLABORATION MEETING BERKELEY:ASSEMBLING THE PROPOSAL

preliminary logo


Summary 1. The MICE (Muon Ionization Cooling Experiment) as presented represents a research and development project to develop an intense source of neutrinos for a future neutrino factory. It is a technical and engineering project more so than an exploratory piece of basic science. Nonetheless it represents accelerator technology at the leading edge, and without results from an enterprise like MICE, it would be difficult in the future to present a credible proposal for a neutrino factory with predictable performance and realistic cost estimates.

THE JOINT CLRC/PPARC PANEL TO REVIEW THE MICE PROPOSAL REPORT OF THE 1ST PANEL MEETING, HELD ON 25 MARCH 2002.


2. The proponents are encouraged to write a full proposal with technical help from RAL who would act as the host laboratory for MICE. The proposal, along the guidelines required by the PPARC Project Peer Review Panel, should address the layout and integration of the experimental facility and cover all safety aspects. The financial, technical and experimental needs should be clearly spelled out along with their probable and realistic solutions.

3. It is important that the proposal can indicate strong UK university involvement of dedicated physicists. The committee was told that even though the HEP community in the UK had indicated a priority for a linear collider as the next global project, there remained a group (~ 20%) with a stated preference for a neutrino factory as the next step. It is therefore anticipated that this group will represent the main signatories of the proposal.


4. The proposal should not address the scientific case for a neutrino factory, but rather concentrate on explaining how the technical and financial uncertainties can be reduced in a future proposal for a neutrino factory, by performing MICE at RAL. It should also attempt to answer the question as to why the proponents believe that the timescale for MICE is immediate. 5. At the stage of producing a proposal the risks to the CLRC are rather small and appear manageable. However the proposal must cover future demands on the laboratory especially the potential impact on the ISIS group and ISIS operations. Should an eventual proposal be successfully reviewed, RAL will become a significant player internationally as the host laboratory for the MICE project. The world needs only one MICE!


questions:

What will MICE be?Who will do what?Who will pay what?When can/should this be done?

Conclusion The Review Panel endorses the collaboration’s request for technical help from the host laboratory in preparation of a proposal to define the layout and integration of this experimental facility and to study the safety issues related to hydrogen absorbers, intense magnetic and RF fields. The Panel reserves the right to examine this proposal, its value for research, its timing and its implications for the domestic programme.

PRIORITIES (status as of RAL coll.meeting)

1. Find a home for the experiment

2. Understand the X ray issue and quantify it in terms of particle detector performance

2.’ Develop reconstruction with noise and efficiencies 3. Choose detectors

3’. Finalize parameters

4. Establish technical specs and cost estimates

4’ Distribute contributions and begin fund hunt mission

5. Write proposal

DONE

getting there, BRAVO!

Crisis…

pending questions on magnet match, beam sizes, absorber design, safety measures

no, but define set of criteria, actions and decision points


.43 X 4 cells = 1.7 m 11.5 MV for 1X 4 = 6.70 MV/m

16 MV for 2X4 = 4.65 MV/m

16 MV for 1X4 = 9.3 MV/m

=> 6.70 MV/m => 4.65 MV/m


Simulation of performance of cooling cell fairly well understood.

Now needed : … simulation of detector response, for design of e.g. downstream PID or to understand performance of Sci-Fi or TPG and first go at some systematics-----

… groundwork by Janot needs to be extended … large organized effort started in August 2002 much exists, some results will already be with us keep going!

SIMULATIONS

conceptual thinking of systematic uncertainties in the measurement needed magnetic field quality / measurements noise and efficiencies in trackers absorber thickness etc…


Proposed grand time line:

2001 Expose detectors to RF radiation (potential show stopper) write first description of experiment with two options

US design (200 MHz) or CERN design (88 MHz) US simulate CERN scheme [and vice versa if possible]

Evaluate availability and cost of main cost drivers: RF cavities / amplifiers/ power supplies/solenoids for each scheme evaluate beams + host labs

1st workshop 25-27 October 2001, CERN ! 16 Nov. 2001 ! Chose technology + host lab, write +

submit LETTER OF INTENT (that was 28 Nov 2001) 25 March 2002 CLRC reviewJune 2002 CLRC + PPARC invite submission of proposal

15/12/2002 Proposal submissionend 2004 1st beam (debugging of spectrometers)

end 2006 demonstrate ionization cooling

after that … … more systematic studies


MICE : WHEN?

GOAL: The long-term goal is to have a Conceptual Design Report for a Neutrino Factory Complex by the time of JHF and LHC start-up, so that, by that date, this would be a valid option for the future of HEP

(European Muon Coordination and Oversight Group, April 2002)

=2007

MICE must have measured cooling end 2006
