Abstract (EN)

HO which is one of the subdedectors of the HCAL calorimeter has RBXs as reading units and there are hybrid photo diodes (HPDs) inside them. Different kinds of noise are present because of the structures of HPDs and RBXs. To find out the noisy HPD/RBXs in HO, the cut is defined by calculating ADC=0 numbers in TSs. With this cut noisy HPD/RBXs which are caused by HPD ion feedback, HPD discharge and RBX noise are found. It is important that to obtain accurate physics data this kind of noise must be considered.
