Abstract

İleri Hadron (HF) dedektörü, Compact Muon Solenoid (CMS) deneyinin her iki yanında bulunup, CMS'nin çok ileri bölgedeki pseudorapidite (3.0 < | η | < 5.0) aralığını kapsar. Her bir HF modülü, demir soğurucuların uzunluğu boyunca ışın demeti eksenine paralel uzanan kuvars liflerinden yapılmıştır. HF, ışın eksenine yakın olduğu için yüksek düzeyde radyasyona maruz kalır. Ve yüksek radyasyon etkisi nedeniyle, kuvars fiberler zamanla bozulmaya başlar. Bu radyasyon etkisini belirlemek için HF detektörüne bazı özel fiberler yerleştirilmiştir. Radyasyonun neden olduğu hasarı izlemek için toplam 56 fiber kanalı kullanılmıştır. Bu çalışma, HF'nin radyasyon hasarının izlenmesi için 2010 yılı çalışma döneminde alınan yerel lazer verileri kullanılarak yapılmıştır. Belirli bir pseudorapidite ve azimutal açıda RadDam kanallarında önemli bir radyasyon hasarı gözlenmemiştir.

Radiation Damage Monitoring for The CMS HF Detector

Abstract

Hadronic Forward (HF) detector is located on both sides of the CMS experiment and it covers the very forward angles of CMS, in the pseudorapidity range (3.0 < | η | < 5.0). Each HF module is made of quartz fibers running parallel to the beam axis along the length of the iron absorbers. Since HF is close to the beam axis, it is exposed to high levels of radiation. And due to the high radiation effect, quartz fibers begin to deteriorate over time. Some special fibers were placed in the HF detector to determine this radiation effect. A total of 56 sampling fibers are used to monitor the damage caused by radiation. This study is performed using the local laser data which was collected in 2010 run period for monitoring of radiation damage of HF. No significant radDam is observed in channels at a given pseudorapidity and azimuthal angle.
