Experimental hall
Experimental Hall

Hall:

L = 47 m W = 12 m H = 8 m

S = 564 m2 V = 4512 m3

Two overhead cranes (8 tonnes each)


Mice hall
Mice Hall

Existing Area & Beam Line

-- is still there - as seen in Summer

-- Beam Line used to end of year



Technical update issues
Technical Update & Issues

  • Beam Line

  • RF System

  • Absorbers

  • Magnets & Cryogenics

  • Detectors

  • Infrastructure & Layout

  • RAL & ISIS Perspectives

  • Programme

  • Expected Progress



Beam line

Pm < 400 MeV/c

Rejection of protons and pions <10%

few muons per ms

Two solutions:

solenoid

cryogenics availability

release by PSI

quadrupoles

Beam Line



Performance
Performance

Rate depends on muon momentum:

e.g. at 200 MeV/c

3000 / ms for solenoid

~300 /ms in quadrupole

(assumed a Ti wire target: 1cm long and 4mm Ø)

Purity should be better than 90% against scattered protons


Rf system

Solenoid Magnet

Cooling Channel

Envelope

RF Cavity

Cavities

Raft

Absorber

Tuning

Bellows

RF System

1 MW per cavity

8MW total

Low Duty Factor

1-2 ms

1-10 Hz

average power

~1kW/Hz


Rf drive

Magnets cryogenics
Magnets & Cryogenics

Principle Issues – Fringe Fields

– Cryogenic Requirements

Blue contours:

10 mT

Orange:

0.5 mT


Detectors

Issues:

SiFi - Large cyro cooling needed for VLPCs

TPG – HV & flamable gas (next to Lig.H cell)


Infrastructure
Infrastructure

Plant: Electrical Power

Cooling Power

Cryogenic System

Hydrogen Delivery & Handling

Installation

phased build of the experiment


Isis perspective
ISIS Perspective

  • Critical Issues: Beam Line

  • Long Shutdown

  • Break into ISIS Synchrotron from MICE Hall

  • Have Shielding available+

  • Have Stands available

  • Competes with other ISIS projects

    • 300 mA upgrade*

    • Second Target Station*

    • RFQ Installation

    • delivery of contracted neutron amp.hours

    • * work in synch. vault +2nd target station – friend or foe?



Expected progress
Expected Progress

Proposal submitted expect the review to take place Mid Feb till May (?) - international review panel

MICE is part of the UK’s Science road map - but funds are not yet allocated

Internal Review  green light following international rp

Management & Oversight Structure(s) need to be in place
