At FJPPL meeting

ACFA-SIM-J activities

ACFA-SIM-J = Users and developers of our tools Topics

Frameworks, Full simulation, Analysis tools Tracker, Vertexing, PFA/Calorimeter, …

TV meeting held weekly + e-mail communication

Participants Tohoku, Niigata, Tsukuba, KEK, Tokyo, Shinshu, Kobe, Saga, … MST-IIT (Philippine), Kyungpook (Daegu, Korea)

Our Software Tools

lcbase : configuration files

Leda : Analysis tools (Kalman fitter, 4vector and jet findinder utilities )

jsf : Root-based framework lclib : QuickSim and other fortran based utilities physsim : Helas-based generator

Jupiter : Full simulation based on Geant4 Uranus : Data analysis packages Satellites : Data analysis packages for MC data

We use only C++, except old fortran tools. Link to various tools at http://acfahep.kek.jp/subg/sim/soft GLD Software at http://ilcphys.kek.jp/soft All packages are kept in the CVS. Accessible from http://jlccvs.kek.jp/

JSF

Framework: JSF = Root based application All functions based on C++, compiled or through CINT Provides common framework for event generations, detector simulations,

analysis, and beam test data analysis Unified framework for interactive and batch job:

GUI, event display Data are stored as root objects; root trees, ntuples, etc

Release includes other tools QuickSim, Event generators, beamstrahlung spectrum generator, etc.

LCIO interface

JSF/Jupiter exact hits LCIO converter Exists since 2005. Pointers to generator particles are not perfect a restriction to

an analysis which relies on generator particle information

LCIO JSF/Satellites converter Work in progress, but not ready yet

Full simulator tools

Full Simulator: Jupiter (Geant4.8.0.p01) Stand-alone package JSFJupiter – Interface to JSF Detector Geometry: parameters are defined by a text file

Stored in a ROOT file for use in analysis job

Analysis Tools: Satellites/Uranus A collection of analysis code based on JSF

IO: Geant4 ROOT object converter Exact hits Smeared hits Track fitter (Khalman) Cheated PFA, Realistic PFA

Background

Low energy e+e- pair background in BCAL region.

Simulated using CAIN data, 500 GeV, Nominal parameter~1/65 bunch of pair backgrounds are simulated

BCAL FCAL

e+/e- tagging in the forward region ? Needs serious study for SUSY physics

CAL Energy Resolution

By H.Ono

Using Geant4 standard physics listAll |cos| region. Barrel/Endcap dependant constant not applied yetConstant term of HD resolution at H.E is large . need check by B.T.

Realistic PFA

Preliminary result is comparable to the results by the tower geometry.

More details in Yoshioka’s talk

Calibration near barrel/endcapGap is not optimized yet

GRID Plan

GRID for ILC is supported by GAKUJYUTSU SOUSEI budget French-Japan Joint Lab. Program

Initial goal As a tool to share data of total size 1~10TB among Institutes in

Japan, Asian, and World Wide.

GRID plan : see next Open question : How to share CPU resources ?
