MICE Funding Agency CommitteePM report

• Overview• Organisation and project management• Schedule reconstruction• The Step IV subsystems

Andy Nichols, STFC, FAC, 15-7-11

Overview

• Muon beamline reliable, decay solenoid, magnets and detectors working routinely

• Target development is going very well, Re-engineered configuration now accepted by ISIS as baseline – a crucial step

• FC #1 manufacture is progressing well, first coil wound, delivery Q3/4, 2011

• Spectrometer solenoids – re-working underway, new confidence in delivery dates (June 2012)

• 2MVA substation upgrade – completed ahead of schedule and working

• PPS - now in use• First EMR planes installed in June, running successfully right

now• Coupling magnets, first coil wound, test is critical to future

plans and decision points, test in US likely, CC delivery plan must be addressed urgently

Organisation and Project Management• Some changes to the project management:

• UK project re-modelled:• UK Project Manager - Alan Grant, DL• System Engineer RAL – Tim Hayler• Project Associate – Andy Lintern

• MICE Project:• Project Manager – Andy Nichols• Integration Engineer – Jason Tarrant• Schedule co-ordinator – Gail Hanson

• MICE Magnet co-ordination team• Engineering – Roy Preece – resident at LBNL since April 1st• Magnetic – Mike Courthold – based at RAL

• Very unfortunately the Hall Manager, Willie Spensley departed in May. AN is default, supported by Vishal Francis. This is an unsatisfactory arrangement.....!• Vital that STFC fills the vacancy – this is a major safety liability

Reconstructing the schedule

• Now accepted that we go straight to Step IV• More subsystem detail has been added to top level

schedule – see later• Aim is to achieve some running with Step V before long

ISIS shutdown in August 2014• This is not a firm commitment; it’s critically dependent on

the Coupling Coil delivery programme• But if running is not possible with Step V, the project will

consider moving to Step VI as soon as possible after the shutdown to advance the schedule

MICE Top-Level Project Schedule

• Step IV• Step V

• Revision date: 17th June, 2011

• Note: items in red text are key schedule drivers• Items in orange text are high risk items• Items in Green text are complete

Step IV subsystemsSpectrometer solenoids

• Workshop held in LBNL during May• Collected all known information on the spectrometer

solenoids• Focussed on:

• Quench protection/detection• Heat load calculations• Assembly/MLI application• Manpower• Shipping

• Representation from s/sol review committee, LBNL team and MIT staff

• Most issues are closed now, delivery plan very well constructed and credible

• Repair has effectively begun

• What are we doing?• Better understanding of 4.2K heatload:

• Pumping capability and monitoring improved• Better instrumentation• Vent lines baffled• MLI on cold mass improved

• Radiation shield made of higher conductivity (1100) series alum

• Better connections of rad. shield to first stage of CCRs• 5+1 cooler configuration accepted as baseline

• Engineering drawings and 3D CAD models rigorously updated - now we know where we are starting from

Revised manpower plan

This is great news – a major step forward

Step IV subsystemsAFC module

• FC #1 is in final stages at Tesla Engineering• Coil is wound, experts agree that it went very well• Cryocooler performance is being physically verified now -

important• Some design issues with outer vac vessel and cold mass

supports need sorting out• Tesla are re-organising their staffing on the project, good

news• Plan to ship to RAL around September/October 2011• Initial testing, powering and mapping will be in building R9• Absorber module #1 was delivered form KEK last month,

effectively ready for use – now in safe storage

Step IV subsystemsLiquid hydrogen delivery system

14

• Four parallel activities going very well:• R&D vessel, pipe and valve work in MICE hall• Venting, vacuum and extraction system outside• Control engineering• Safety planning and admin

• R&D vessel now installed and liquefying helium successfully• Process now entirely operated by the control system – great effort

from DL group• Exterior work well underway – large fans have been tested, most

civil engineering work is done• Safety & Admin:

• Successful LHe test needed for input to Hydrogen safety case• Pre-operation safety review being organised now, aiming for

later this year• Formal monthly exchange with ISIS Safety
