22nd June, 2010
Slide 2
2 Circa 1963............Circa 2007 But this is what were aiming
for...........>>
Slide 3
3........Installation of MICE Step VI in R5.2
Slide 4
Progress since 2007 Starting at the bottom: Demolish old floor
Install new false floor Acts as base for whole cooling channel
Conventional construction, but has to be reasonably flat & true
Able to withstand 50 tonne quench force And, most important, able
to be fiddled with extensively in future! 4
Slide 5
Progress since 2007 Next level: Provision of baseplates for
spectrometers 1 & 2 Accurate and repeatable locations for
detectors Able to withdraw from beamline for servicing Magnets move
on airpads Non-magnetic construction Able to react 50 tonne quench
force 5
Slide 6
Progress since 2007 Provision of two magnetic shield walls Act
as return yoke for cooling channel Protect ISIS Linac and MICE
control room from stray fields 150 tonnes of magnet iron, delivered
on time by UK industry And supporting framework/galleries 6
Slide 7
Progress since 2007 Have also done much routine but essential
infrastructure work: Provision of CCR cooling water system Uprated
compressed air system Provide air conditioning Uprated the domestic
power, lighting & fire detection Compliance of R5.2 to all
safety & local rules Extract fans Accommodation for 28 CCR
compressors and services General civil engineering work Much help
here from Building Projects Group (BPG) and ISIS at RAL Formal
handover from BPG 16 th June many thanks indeed 7

MICE compressed air system MICE Trench Behind R5.1 70 MeV plant
room Guaranteed line 5.5bar (actual 6.5 - 7.2psi)
Slide 9
Schedule and planning considerations All this brings us to June
2010: Have been ready for Steps II &III for a few months Were
geared towards Step II start in Mid- May, 2010 Wont happen till
later in 2011, What to do........? 9
Slide 10
Re-defining the UK project Steps II & III are delayed for
at least one year UK installation team and infrastructure
construction were very carefully geared towards spectrometer
solenoid #1 arriving at May 15 th We want to hold the installation
team together, so: Advance work on the LH2 system - see also Matts
talk Vent system Civil engineering Pipe/valve & gas panel work
RF power work Design of waveguide/power/cooling infrastructure,
placement of amplifiers Hands on work at DL with RAL team second
LBNL amplifier Both RF & LH2 projects contain open issues
better to find out early 10
Slide 11
11 All this has to be designed & built outside R5.2. LH2
external infrastructure
Slide 12
RF Power Two RF amplifiers from LBNL are being reconditioned at
DL One is complete, the other is waiting Plan to deploy some of
existing team on second amplifier Important to do this early while
we have time Led by Daresbury Lab Very beneficial DL/RAL
relationship RF amplifiers quite big, 4m high and 1 tonne we have
to fit four of them in a very confined space 12
Slide 13
13 Need to fit all this.............Under here!
Slide 14
Electrical Engineering Also led by Daresbury Lab: All detector
wiring and cabling Electrical services in general Complete
implementation of PPS (Personnel Protection System) Contribution to
electrical substation upgrade project Conventional and S/C magnet
power supplies Cooling Channel controls project Target power,
readout & controls Major contribution from BPG: Power for
heating, lighting Implementation of fire detection A/C power
Electrical substation upgrade project 14
Slide 15
Electrical substation progress The problem: The electrical
supply in R5.2, the MICE Hall, needs to be upgraded to 2MVA,
certainly to run at Step IV and probably at Step III Most of the
power is required for CCR compressors, latest predictions are
(5+1)x2 for spectrometer solenoids and 3x2 for coupling coils The
present layout in R5.2 gives 1.25MVA and is based on fifty-year old
equipment that has not been used to full capacity for many years
The ingoing cable to R5.2 has adequate capacity and does not
require any work Historically, this has been treated as a host-lab
contribution and has never appeared MICEs costed plan But we
understand the need for a discussion 15
Slide 16
16 STEP I Present power Rating (1.25MVA) Point at which were In
trouble
Slide 17
17 Present configuration of Spectrometer sol 3 x 2 stage CCR +
1 single stage Proposed configuration: 4 (or 5) 2 stage CCR + 1
single stage Coupling magnet will likely need Three instead of two
2-stage CCRs What all the fuss is about: Cryomech two-stage Closed
Cycle Refrigerator MICE something of a pioneer here Not usual to
cool large magnets with CCRs
Slide 18
Electrical substation Four technically viable solutions have
been identified by BPG and DL Varying degrees of cost/technical
capability We have been asked to follow up the two cheapest options
Meet again with STFC Management on 8 th July Hope to know which
version then Lead time is dominated by major components (around one
year), but we also need to add design & installation time So if
we begin now, might just be OK for Step III in late 2011 18
Slide 19
Future Plans Between now and 2014, MICE has to successfully
build and install several large and complex subsystems, for
example: Two spectrometers Three absorber-focus coils Two
RF-coupling coil magnets And all their services and ancillaries In
a very confined space to a reasonable degree of accuracy Also have
to accommodate several different engineering cultures and standards
Have demonstrated that a more rigorous engineering approach pays
dividends eg, the MICE target Now want to read that across to the
other subsystems Easier said than done....... 19
Slide 20
Future plans So were changing the emphasis slightly, from
infrastructure and surroundings to the subsystems and interfaces
Top level assembly now successfully driven by one (large!) Solid
Edge CAD assembly RAL engineering team is being reinforced Full
time integration engineer is appointed Am now working on support
for him Monthly MICE Technical Board will be forum for integration
issues Integration activity will be centralised at RAL - important
Discussions just beginning with subsystem owners to encourage
information flow 20
