|The design must be coupled well with a compensated forward e/m calorimeter for high precision jet energy measurements.
No archive versions
|Forward HCal shall play a crucial role in jet energy and kinematics reconstruction in the hadron endcap, complementing tracking and e/m calorimetry in the particle flow algorithms, and be consistent with the ePIC detector solenoid design
|Granularity (transverse tower size) should be adequate to resolve deposits from different charged and neutral hadrons taking into account the local abundance, resulting in transverse tower sizes of at least ~5x5 cm^2 for \eta < 2.5 and 3x3 cm^2 for 2.5 < \eta < 4
|Must have tower depth of 6-7 interaction lengths (together with the e/m section) in order to avoid longitudinal leakage for highest energy hadrons at the EIC.
|Granularity (longitudinal tower size) should be adequate to allow for association of showers starting at different depth to the corresponding charged and neutral hadrons. At least 5 longitudinal segments should be read out to determine the shower maximum reliably. For higher rapidity the segmentation should be increased due to the higher particle density
