MICE Project Report

Paul DrummCollaboration Meeting 10

Rutherford Appleton LaboratoryOctober 2004


Progress since Osaka• AFC…

– …

• Cavity– …

• RF amplifiers on the move!– despite all the problems

• Tracker– …

• Beam Line– …

• PID


Technical Issues

• Cryocoolers are still with us!– I believe that MICE is in a position to finally

conclude on these• Hydrogen – established at Osaka• Helium• What are the parameters & what are the risks?

– Cryocoolers & Liquid Helium Strategy• Discussion at the AFC meeting yesterday,• Mike Green discussion today,• Cooling channel parallel session today & tomorrow• Collaboration board discussion tomorrow


Technical Issues

• Strategy with R&D– Hydrogen management & safety system

• Hydride bed• Safety operating parameters

– Absorber + Cryocooler risk reduction• Especially parameters for helium• Charge to AFC group to develop an R&D plan


Technical Issues

• RF System– Scheme is sound, but– What are the problems to bring into

operation?– What is the expected performance?– The equipment is on the move

• Flown into the UK on Sunday


Technical Issues

• No longer are we so worried about:– Shield plates

• Tracker – nice solution• Spectrometer end shielding

– Module Connections• Converged on a good solution

– Forces – no longer strong issues!• Details important!• Some clarifications needed

– forces to floor or along channel

• no showstoppers


Technical Issues

• Tracker Performance & Endorsement– MICE note– Discussion in parallel session– Presentation to the collaboration– Referees Report– Discussion at Collaboration board


Design & Safety Review I

• Has the design of the AFC module moved significantly away from that reviewed?– Philosophy has not changed

• idea of barrier to the ingress of oxygen• Guard against a two fault scenario• Hydride bed storage of hydrogen

– Scheme is significantly changed • Cryocoolers (not a safety issue)• Hydrogen siphon system

– gas-liquid loop– Is this a safety issue?


Design & Safety Review II

• Is it time to bring all MICE designs to review?– In-line with initial scheme– Include tracker & tracker solenoid & other

detectors– Include RFCC module & beam line– Involve RAL engineers– Rehearsal for a final review

• Second half of 2005…

Design & Safety Review II

• Is it time to bring all MICE designs to review?– In-line with initial scheme– Include tracker & tracker solenoid & other

detectors– Include RFCC module & beam line– Involve RAL engineers– Rehearsal for a final review

• Second half of 2005…


Design & Safety Review III

• Proposal is to charge the AFC group with the task– Broaden membership– Develop a plan to take us to the next review

• Develop details of design• Develop HAZOP assessment; • operating procedures• Develop R&D plan

– R&D plan interacts with design• Time scales & Steps to take MICE forward


Technical Reference

• On the web (from MICE web page)– Is very nearly complete (largely is and ts)– Read through and be constructively critical!– Will become the Baseline design of MICE!

• Passed up to the executive & collaboration boards

• Need to conclude by the end of this week


What it means

• The Technical Reference Document will replace the MICE proposal of January 2003 as the baseline design of MICE

• Changes to the baseline design will then be published as change notes until the next issue of the full baseline design and will be maintained on a server at http://www.eng-external.rl.ac.uk/MICE-GEN/


Schedule I

• Key milestone is the ISIS shutdown in 2006: likely dates are April-September

• MICE-UK has to be ready to – install the front end of the beam line;– Install shielding in such a way that short

shutdowns can be used for final installation– Long delivery time expected on fridge for

muon solenoid– We have a plan contingent on success at the

next GW review


Schedule II

• The schedule of MICE depends on what happens in the next 12 months!

• In the US, we look forward to a resolution of phase 0 funding request

• In Italy, we look forward to a response to the EOI

• In the UK, we have the opportunity to liberate funds for the next FY– Cost & Schedule Review– Gateway review in December

UK Process

• Continued endorsement of MICE by RCUK

• Gateway 2 & 3 review

• Presentation of MICE to the PPARC Council

• Presentation of MICE at the Science Committee of PPARC

• Cost and Schedule Review


Cost & Schedule Review

• Reports to JMPB (Ken Peach)GW1: The Review Team recommends that an independent Cost

and Schedule Review should be set up as soon as this is practicable and that its conclusions be included in the submission to the next Gateway Review.

Charge:– To review in detail the cost and schedule of the proposed work

to implement the MICE Muon Beam and associated infrastructure;

– To review in detail the cost and schedule of the proposed UK contributions to the MICE project (the MICE-UK project) over the period April 2005 to March 2007;

– To review and comment on the cost and schedule of iMICE as documented in the MICE Work Breakdown Structure;

– To provide a written report to Professor K.J. Peach, Director of Particle Physics, RAL.


Documents for Review

• Project Specification – UK Activities– Milestone plan

• Project Plan (including)

• Risk Register

• WBS spreadsheets

• Technical Reference Document


Cost & Schedule

• Strategy– Set of milestones matched to the MICE schedule

• Release of funds to start to – Build the beam line & complete the FC design work– Complete the Tracker– Engage in R&D

– Hydrogen – Hydride bed; Learning & Proving;

– Absorber system & Cryocooler

– Investment in Safety;

• Difficulty for items for MICE stages III…VI


Cost & Schedule

• Held up on– FC build– MICE infrastructure– RF power system

• To unlock these activities needs the appropriate steps within the collaboration to the key MICE stages


Cost & Schedule• MICE UK Cost & Schedule Review

– Muon Beam Line– Design Completion– MICE-UK R&D Risk Reduction

• R&D aimed at Hydrogen System & Absorber• R&D to get one RF system to work

– Spectrometer instrumentation• For MICE Stages II & III

– Coil Fabrication• For MICE Stage IV, V, VI

– Infrastructure for MICE• Staged approach

– Cooling system– RF


Formal Gateway Review

• MICE-UK Project Review:– December 20th & 21st.– Review team will have the results of the Cost

& Schedule review from the 12th November.– Project Structure &– Project Management Plans– Document addressing issues from Gateway 1


Formal Gateway Review

• MICE Project Board– Peach, Wade, Long,Drumm,– Likely to be a representation of MICE

• Material– Responses to Gateway1 review

• Tempered by latest developments

• Review TeamCox (Culham)Greenhalgh (RAL); Costigan (OST); Dowell (B’ham); Murray (RAL-sci.secr.)
