1 Status Report Jieun Kim Kyungpook National University RENO MC Simulation Meeting (Jun 22, 2006)

2Outline 1)Download & install “MyGLG4sim” – full detector simulation 2)Check out the output (basically, followed up the status talk files of Dr. E.J.Jeon) (but, before gadolinium support, yet) 2)Plan

3 MyGLG4sim (HowTo) Linux version (at present in KNU) -> FedoraCore-5, kernel , -> gcc version (Red Hat ) Download & Install 1)root_v source.tar.gz 2) clhep tgz 3) geant4.6.2.p02.gtar.gz 4) geatn4-data_files 5) glg4sim_0_9_5.tar.gz 6) MyGLG4sim.tar.gz (full detector simulation)

4 Target vessel Gamma catcher Buffer tank Veto tank Cavern (Tunnel arch + pit) Rock

target vessel : scintillator 구성 물질 mineral oil 80% pseudocumene 20% PPO fraction 1.5g/l gadolinium 0.1% -> check

 Inverse Beta Decay Event

7 MyGLG4sim (Full Detector Simulation)

8 Generator Level (1000 events) Anti-neutrino position momentum

9 e+ momentum position

10 Generator Level (1000 events) Neutron position momentum

11 Generator Level (1000 events) Kinetic Energy Dist. e+ Anti-neutrino neutron

12 Plan 1. Need to study more on the physics process 2. Need to think what variables we can look at 3. Need to understand more on the code behavior 4. Make sure for Gd support on the code 5. Look at variables before & after detector simulation
