With the upgrade of the beam energy to 12 GeV, the kinematics of the reactions will change dramatically. Since the particles will have greater momentum, they will be boosted into the forward direction at smaller angles with the beam direction. New detector systems will be added to the CLAS to sort out the spray of particles in a smaller space. The new detector system will be CLAS12.
One new system added to CLAS12 will be the Pre-shower CALorimeter (PCAL). Its job is to increase the identification capabilities of the existing Electromagnetic Calorimeter (EC). This will be needed by the CMENP group to identify neutral pions that decay into pairs of gamma rays.
The CMENP group is writing the software to reconstruct particles from the electronic output of the PCAL. The software is written in JAVA in the CLARA framework. CLARA is a service-oriented architecture that bundles the algorithms to allow the CLAS12 analysis to be performed in a cloud computing environment.
