G. Battistoni, A. Ferrari, C. Pardiin collaboration with LNGS/Aq group
Some progress in the light production/transport simulation
in ICARUS using FLUKA
Reproduce some muon data from actual data(both with “vertical” and “horizontal” trigger)
with and without Rayleigh scattering
Usual conditions:
no reflection from cathode 128
cathode holes at 60%
24000 photons/MeV @ 128 nm
no detailed PMT eff.
Comparison with data

From last J. Lagoda presentation:
“Vertical” muons
This work: Reproducing muons from Run 649 (reconstruction got from J. Lagoda + LNGS people)
“Vertical” Muons
No Rayleigh Rayleighwith = 90 cm

This work: Reproducing muons from Run 781

“Horizontal” Muons
Remarks
Introducing Rayleigh scattering increases the slope inthe plot of Npho vs distance from PMT
Slope of ADC counts vs distance from PMT in real datais closer to the case of no Rayleigh Scattering (~as in first LNGS simulation)
But R.Sc. must be there ! (plus maybe some absorption)
So what is missing?
Are there any saturation in PMT pulses in real data?NOT IN THESE RUNS (Selected events)
Some news about FLUKA
Since Feb 19th there exists a scientific agreement between
INFN, CERN (EP and AB divisions) and FLUKA authors
to develop maintain and distribute FLUKA to HEP community
Main milestone:a full release within 18 months
with a proper licence(already a milestone of INFN Gr.V)
A Beginner's course
My idea and intention is still valid (delayed due to FLUKA issues and work on T600 paper)
LNGS agrees to host a FLUKA course provided it is general and not only for ICARUS.
This is not a problem
Project: 3 days, including examples dedicated to underground physics plus a dedicated appendix to specific Icarus library and cases
When: we cannot think of it before CHEP-2003 (end of March) most likely April or May
