Bob Palmer’s talk at “NF-MC synergy” meeting, Fermilab, 13 June 2008
Needs some study & optimisation
There will be ~6 months – 1 year between Steps III and IV
We should think of doing this (Chris has done some work already)
Could also imagine STEP IV.1 (no RF but better optics than III.1/2
STEP III.2
STEP V.1

SENSITIVITY OF COOLING TO dE/dX MODELS
Talk by R. Fernow at NF-MC synergy meeting, 13 July 2008
Stronger sensitivity of cooling and muons/proton to dE/dX and multiple scattering models than expected (see RF’s talk).
Important to get right for predicting performance of NF & MuCollider.
Problem with tails of distributions???
Tails are small-ish, shouldn’t matter??
Some discussion of possibility/necessity of clean dE/dX measurement
(~Muscat + Energy Loss)
Can MICE, e.g. STEP III, usefully measure dE/dX distribution???
(Probably doesn’t have good enough energy resolution; need de <<1 MeV
Very important that we understand what G4MICE (& ICOOL) are using – only ‘physics’ knobs in simulation are dE/dx and scattering.
Believe G4 has only one model of dE/dX distribution (anybody know?); several are implemented in ICOOL.
This will be important when we start to compare measurements & simulations.
