100K MC Challenge at CC-J

!!!Under Construction!!!

What is "100K MC"?

The experiment of Relativistic Heavy Ion Collider (RHIC) at PHENIX has been successfully started in summer 2000. A large fraction of Au-Au collision data has been taken at sqrt(s_sub{NN})=130 GeV, while PHENIX had been set up with a few different configuration.

In general, Monte Carlo (MC) simulation is very important to understand the detector characteristic (acceptance, efficiency etc.) and to evaluate a reconstruction program. The goal of "100K MC" project is to produce realistic and huge simulated data with various PHENIX Year-1 configurations.

PHENIX started with "retractd arm" position. (run00a) Both, West and East, central arms were "opened" about 40 cm against the central magnet. The magnet was not turned on with this configuration. After the MVD partially installed, the central arms had been "closed" and the data were taken without magnetic field. (run00b) Originally, response chain (PRDF production) and reconstruction chain (DST production) would run separately. However, we have changed our plan, "camTask*.C" jobs generates DST directly from PISA output.
