17 June 2008 PC 3203

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.
