Title: Alain Blondel


1
MICE video conference 11 November 1600 GMT --
Announcements .. Peter Gruber has prepared a
template for proposal .. action lists on the
web -- Ken Long time lines -- discussion
toward the finalisation of MICE set up ..
Derun Li comments on RF .. R.B. Palmer
progress in simulations (excused a few
transparencies Re envelopes) .. Iouri
Ivaniouchenkov or Ed Black toward a safety
scheme. .. Discussion.

Experiment concept and magnetic simulationc
Palmer ( BNL team) ? 15 November 2002 post
envelope calculation Simulate new coil
geometry match and simulate other betas and
momentums (solenoid configuration requested)
write for proposal. ?later Be available for
calculation Experiment simulation
Torun/Catanesi action list - Complete
digitization for full detector chain -- Oct 30 -
Make a working release -- Nov 1 - Implement
standard RF induced background -- Nov 5 - Study
detector performance -- Nov 15 - Make plots for
proposal -- Nov 15 -------------------------------
---------------- deliverables pictures of muons
through the detector in G4MICE simulations of
SCIFI tracker with inefficiencies noise epsilon
in / epsilon out Particle ID -------------------
----------------------------- - Another release
-- Nov 11 (to include background source,
virtual detectors, global tests, more geometry
and materials details, TPG reconstruction if
available) - Continue performance studies and
revise plots -- Nov 30 - Improve neglected items
(proper testing and documentation, analysis
tools, visualization, etc.) -- after proposal
submission - Another workshop to decide the rest
-- ?

Absorbers Cummings/Ishimoto ACTION need to
decide on the aperture of the absorber
window will need integration of timelines between
focusing magnet and absorber. global design of
safety windows arrangements?
  • RF Li, Haseroth
  • cost has gone up to 4.7 M (incl manpower)
  • need bare cost for proposal
  • RF plans
  • measure Rmag (magneto resistivity of copper) vs
    mag field
  • cavity surface examination
  • insert TiN-coated berylium window
  • start RF conditionning with this.
  • it is possible that we will know more about RF
    noise when proposal is actually reviewed.
  • running in gradient field (not flip) to check
    more realistic configuration
  • NB LN2 cooling possible for short periods, will
    gain factor 1.7 or so in gradient, with
  • Unknown effect on noise
  • will stay with 4 cells per cooling section.

Magnets (M.Green) rather short procurement times
for the couplng solenoid and for the flip pair.
Spectrometers are longer will last at least 24
mo to get first solenoid, second one 2-3 mo
later. Action list check vialbility of
various configurations (max B in condictor,
forces) Standard Lattice 200 MeV/c, beta 42 cm,
Detector B 4.0 T Standard Lattice 240 MeV/c,
beta 42 cm, Detector B 4.0 T Standard Lattice
200 MeV/c, beta 25.4 cm, Detector B 4.0
T Standard Lattice 175 MeV/c, beta 16.7 cm,
Detector B 3.5 T Standard Lattice 150 MeV/c,
beta 10.5 cm, Detector B 3.0 T Standard
Lattice 140 MeV/c, beta 5.5 cm, Detector B
2.8 T (variable B in detector sol. allows fewer
PS) will give to RAL the currents for same
polarity configuration magnetic measurements
need to be included in cost JM Rey will write a
couple pages for the proposal

Detectors (Alan Bross, Vittorio Palladino) need
decision on tracking around 2003 summer tof/
cerenkov e-id ready end 2004 OK Sci-Fi schedule
well known TPG 1 yr of RD tracking decision
point summer 2003 500 vs 4000 M (not counting
cooling requirements) TPG need to test small
TPG in front of RF cavities and to understand
effect of noise on reconstruction also issue of
HV in vicinity of LH2.
McKigney / Norem RF noise presented a
schedule of RF studies and a scaling formula for
noise in 00 MHz cavities shielded by absorber
(AEphoton emission prob (l_abs/X0 ln
(Emax/Ecut)) photon conversion prob (x/X0 of
det)) some results on BKG source simulation
should be available by mid january make photos of
the RF cavities and windows before it is
dissassembled and reconditionnned cost of RF
56000 / (Kaplan has the money. he says)

Beam line (Drumm) Beam Line- deadline 15th
November Document beam line for proposal with the
following Sections Overview
Proposed Target Changes Expected
Performance and Time Structure of the beam
Time Structure (of the beam) Pion
production Beam line options -
Quads/Solenoid Expected Performance-
Quads/Solenoid Proposed Measurements of
the beam line Performance Time Scale and
Schedule The ISIS Schedule MICE
Beam Line Schedule Integration Black,
Iouri decision on proposal version of experiment
is needed safety issues communication! need
weekly communication system of integration group
IOURI WILL ORGANIZE THAT.
