Jupiter

A.Miyamoto at HDCMeeting (1-Oct-2004) 5 Jupiter Features:  Modular structure for easy update, install/uninstall of sub- detectors  Powerful base classes that provide unified interface to  facilitate easy (un)installation of components by methods such as InstallIn, Assemble, Cabling  Help implementation of detailed hierarchiral structures. This helps to save memory size.  Minimize user-written source code by –Automatic naming system & material management –B-field compositions for accelerators  Input : HEPEVT, CAIN (ASCII) or generators in JSF.  Output –Output class allows extrnal methods. Using this mechanism, it can output ASCII flat file and JSF/ROOT fie. Core developper: K.Hoshina and K.Fujii : Geant4 based Full Detector Simulator

A.Miyamoto at HDCMeeting (1-Oct-2004) 15 Calorimeter in Jupiter An accuracy of simulated results depends on precision of Calorimeter geometry. In the currenet version, we are implementing an ideal geometry to know ultimate performance  pointing tower structure, no crack between towers  > 100 layes of absorbers and sensors  Mini-tower can be defined within tower to small cell structure. Simulate with a small cell structure and merge cell signals appropriately at later analysis stage to save CPU and storage space.  Tower geometry, materials and granularity can be modified easily. Current status:  Geometry are implemented.  Studying performances such as CPU time, Output data size, Energy response, etc Tower structure EM HD

Get JUPITER source from CVS Set environment parameters, such as JUPITERROOT  See jlclogin:/proj/soft/Release/x.xx/setup.bash for example Then do “make” at the Jupiter top director. To run, type $ Jupiter … prompt> /run/beamOn 100 Read pythia_event.data and hit information is written in a file, hit.dat

A.Miyamoto at HDCMeeting (1-Oct-2004) 17 Status of Jupiter We have spent ~two months to implement fine structures of Calorimeter. Status  CAL tower of ~170 layers of 4cmx4cm tower  ~9000sec to generate 100 ZH events at 350 GeV  Output data size exceeds 2G Bytes at ~0.5K events –Need to reduce output data size or JSF update to support multiple-file output –Without output, run more than 5000 events  1cmx1cm tower  Takes 2 hour for geometry initialization  ECAL energy resolution  ~19%/Sqrt(E), if this is due to large cut-off, CPU time may be increased in order to get reasonable resolution

A.Miyamoto at HDCMeeting (1-Oct-2004) 22 Status of Metis Current aim is to prepare a minimum set of Metis module 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 fitter and cluster maker, etc are in preparation in order to know an ultimate performance. We are developing basic classes now. Each modules are independent, thus shall be easy to implement different reconstruction algorithm according to interests
