Upgrade plans for hadron calorimeter in the CMS detector
The Large Hadron Collider (LHC) is expected to undergo upgrades in two phases in next decade. Luminosity at the completion of the second phase is expected to increase by an order of magnitude to 10$^{35}/$cm$^2$-sec. The upgrade of the CMS Hadron Calorimeter (HCAL) is being planned to sustain an inc...

| Sumario: | The Large Hadron Collider (LHC) is expected to undergo upgrades in two phases in next decade. Luminosity at the completion of the second phase is expected to increase by an order of magnitude to 10$^{35}/$cm$^2$-sec. The upgrade of the CMS Hadron Calorimeter (HCAL) is being planned to sustain an increased dose of radiation and challenges arising from occupancy rate due to higher luminosity. Replacement of existing photo readout device by silicon photo multipliers is being planned for the HCAL. Detailed studies performed on this device are presented. Plans on the upgrade of the front-end electronics, DAQ, trigger, and the active elements in some part of the detector will be discussed in detail. |
