QuickSim overview
Purpose: simulate detector effects for physics study Components:
VTX, IT, TPC, CAL Model for tracker
circular trajectory parabolic trajectory With multiple scattering, without energy loss Equally spacing sampling
Model for Calorimeter EM signal by e/, HD signal by hadron, muon no signal Segmented calorimeter. Lateral spreads are generated b
y an analytic form.

QuickSim update
Change in source code Gas density in tracker, Cal. Shower shapre can be changed by inp
ut data card. GLD-V2 : new parameter file for GLD configuration
Beam pipe: r=1.5cm, Be, 25m VTX : (r,thickness)=(1.9cm,20m), (4.1,200), (6.3,200)
not consistent with Sugimoto san’s parameter yet. Beam pipe and VTX 1st layer parameter are not realistic to rep
roduce performances. TPC: r=40~205cm, 200 sampling,
r=150m, z=1mm CAL : EM segmentation 2cm equivalent
HD segmentation 6cm equivalent Parameters for lateral spread have not been changed.

QuickSim Tracker performance
Momentum resolution similar to the Jupiter/Satellites resultIP resolution at 1 GeV is about factor 2 worse than the Jupiter/Satellites result

Higgs signals by QuickSim
Mh=116.2GeV/c2
M=3.81 GeV/c2
Mh=118.4GeV/c2
M=4.02 GeV/c2 Mh=117.6 GeV/c2
M=4.808 GeV/c2
Criteria for event selections are same
Possible improvments: - parameters of track-cluster matching - detector configuration dependant event selection - ……

installation of sub-detectors Geometry
parameters ( size, material, etc ) can be modified by input ASCII file.
Only simple geometries are implemented ( OK for the detector optimization )
Input: StdHep file(ASCII, Binary), HepEvt, CAIN, or any
generators implemented in JSF.

Jupiter for background studies LCBDS
Developed at U. of Tokyo;Tanabe san, Abe san, and their colleagues. Geant4 based simulator for the beam delivery and the dump line of ILC
( from the exit of main linac to the beam dump) Inputs to LCBDS :
SAD data file are used to define geometry easy to follow changes of ILC parameters.
Accelerator components are approximated by cubic and/or cylindical shape Output from LCBDS:
Synchrotron ’s, muons, off-momentum electrons, etc are created Particles information near the interaction point are saved in StdHep ASCII f
ormat Inputs to Jupiter Status
First version to write StdHep data were prepared. Waiting for the confirmation by Jupiter.

Metis package Metis is a collection of reconstruction tools for Jupiter data. Initial aim was to prepare a minimum set of Metis modules for
studies of Particle Flow Algorithm. Novice users will be able to do physics analysis using
information of PFO classes. As a first step, a cheated track finder and a cluster maker, etc
are in preparation in order to know ultimate performance.
Each module is independent, thus it is easy to implement different reconstruction algorithms
Real clustering codes are prepared using this framework

Summary Studies of detector performances based on Jupiter/Satellites have be
en performed by many people, which are covered by other parallel session talks.
Implementation of new geometry in Jupiter has started for studies of background and IR design.
QuickSim Performance of tracker and Higgs signal were studied using GLD-V
2 parameter set. Detector parameters can be changed easily, but consistency with
full simulator is not automatic.Please use it with caution.
Jupiter users/developers meet every Tuesday 13:30-15:00 (JST)at TV meeting (KEK MCU, ID 31300). Please join.
