The Hadronic Calorimeter (HCAL) in the CMS experiment at the Large Hadron Collider (LHC) at CERN has been designed to measure the energy of jets which are the signature of quark and gluons produced in strong interactions. The jet measurements is the crucial importance for both detector performance and studies Standard Model (SM) and Beyond the Standard Model (BSM) physics analyses such as supersymetry (SUSY), Higgs boson and heavy gauge boson researches. The other important feature of jet measurements is that it tests the performance of simulated proton-proton (pp) collision data produced with Monte Carlo (MC) simulations. Precise and accurate measurement of jets of great importance in HCAL especially in central region of the calorimeter (|η|<3.0) and concerns many physics analyzes performed in the CMS experiment. Very large aberrant GeV-TeV scale noise is detected in the Hadronic Barrel (HB)and Hadronic Endcap (HE) sub-detectors located in the central area of HCAL, and it was understood that these GeV-TeV scale noise is not caused by pedestal and other noises. The GeV-TeV scale noise is due to the Front-End Readout Systems in the HB and HE calorimeters. The characteristics and analysis of the noise originating from the GeV-TeV scale Front-End Readout Systems in the HB and HE calorimeters are presented in this study for both 0 "T" and 3.8 T magnetic field.

CERN'deki Büyük Hadron Çarpıştırıcısındaki ( BHÇ) CMS deneyinde bulunan Hadronik kalorimetre (HKAL), güçlü etkileşimlerde üretilen kuark ve gluonların imzası olan jetlerin enerjisini ölçmek için tasarlanmıştır. Jetlerin ölçümleri, hem dedektör performansı hem de Süpersimetri (SUSI), Higgs bozonu ve ağır ayar bozon araştırmaları gibi Standart Model (SM) ve Standart Model Ötesi (BSM) fizik analiz çalışmaları için büyük önem taşımaktadır. Jet ölçümlerinin bir diğer önemli özelliği ise Monte Carlo (MC) simülasyonları ile üretilen benzetilmiş proton-proton (pp) çarpışma verilerinin performansını test etmesidir. HCAL'de özellikle kalorimetrenin merkez bölgesindeki (|η|<3.0) jetlerin hassas ve doğru ölçümü CMS deneyinde gerçekleştirilen birçok fizik analizini ilgilendirmektedir. HCAL'in merkezi bölgesinde bulunan Hadronik Fıçı (HB) ve Hadronik Uç-kapak (HE) alt detektörlerinde çok büyük anormal GeV-TeV mertebesinde gürültü saptanmış olup, bu GeV-TeV mertebesinde gürültünün pedestal ve diğer gürültülerden kaynaklanmadığı anlaşılmıştır. GeV-TeV mertebesindeki gürültünün nedeni HB ve HE kalorimetrelerindeki ön-uç readout sistemlerinden kaynaklanmaktadır. Bu çalışmada, HB ve HE kalorimetrelerindeki GeV-TeV ölçeğindeki ön-uç readout sistemlerinden kaynaklanan gürültünün özellikleri ve analizi 0 T ve 3.8 T’lık manyetik alan için sunulmaktadır.
