Advanced Hadronic Energy Reconstruction in the CALICE AHCAL Technological Prototype — •Christian Graf for the CALICE-D collaboration — Max-Planck-Institut für Physik, München, Deutschland
The CALICE collaboration is developing concepts for highly granular calorimeters for future e+ e−-colliders, such as ILC or CLIC. One of them, the analog hadronic calorimeter (AHCAL), is a sampling calorimeter using 3x3 cm2 scintillator tiles as active material, read out by silicon photomultipliers (SiPMs) and steel or tungsten plates as absorbers. A series of test-beam campaigns was carried out with a technological prototype in order to prove the feasibility of the technology for such a device. The technological prototype is constructed with front-end chips integrated in the active layers and the design is scalable to a full detector. A new feature compared to previous prototypes is the capability to provide hit time information for each calorimeter cell.
The high granularity of the prototype allows for advanced energy reconstruction methods. This contribution will discuss wether the hit time information can be used to enhance the energy reconstruction using simulated data. Additionally, methods will be explored in order to further improve the energy reconstruction incorporating several event variables in the energy reconstruction.
