Workshop on Tracking Detectors in High Energy Physics

25 May 2015, 08:00 → 27 May 2015, 18:00 Asia/Karachi

ROOM # 108, ACADAMIC BLOCK (NATIONAL CENTRE FOR PHYSICS, ISLAMABAD)

The aim of the activity is to provide a platform to the people working in the field of semiconductor detectors to collaborate with each other by sharing their knowledge and experience. It will also provide an opportunity to students to understand the basic principles and applications of silicon tracking detectors in high energy physics and related topics. The workshop is also useful for the researchers working in other tracking detectors such as Resistive Plate Chambers (RPCs) and Gas Electron Multiplier (GEM). The international and local speakers from CERN and different universities/Institutes of Pakistan will present their work related to the subject in focus.

13:30 → 14:20 The Physics of Silicon Detectors for HEP Applications

Silicon detectors play an important role in tracking in today’s High Energy Physics experiments. They are widely used in vertex detectors and the developments of the past decades have greatly improved performance with respect to resolution and radiation tolerance. The contribution will give an introduction to the underlying physics and the most important characteristics of silicon detectors. The design and production of position-sensitive devices will be highlighted together with the basics about radiation damage and the design of radiation-hard devices. Furthermore, the most widely used and most promising types of detectors for future applications will be introduced briefly.

Speaker: Georg Auzinger (CERN)

14:20 → 15:10 Physics of diamond detectors

Diamond can be used as active medium in ionizing particle detectors. The principle is very similar to an ionization chamber. An applied electric field separates the charge carriers, created by ionization, and the charge drift is measured as a detector current. Diamond is often used in a similar fashion as silicon detectors, but show different detector performance. Fast signals, good radiation hardness and low leakage current even after irradiation are some of the unique qualities of diamond detectors. During the lecture we will discuss diamond material and artificial growth of diamond, electrical contacts and electrical properties of diamond detectors. The radiation hardness of diamond is widely regarded as very good and some insight to radiation hardness is given. Electric field effects due to polarization will be discussed. At the CMS experiment diamond detectors are used in the Beam Condition Monitors (BCM). The BCM systems will be shown as an application of diamond detectors.

13:30 → 14:20 Performance of the CMS Strip detector and Phase 2 upgrade

The CMS Silicon Tracker is the largest silicon detector ever built, containing 10 million readout channels. This presentation will cover the operational experience during the Run1 period and the commissioning during LS1, including challenges and detector status before the Run2 period. The Phase 2 upgrade of the LHC machine, scheduled in 2020s, will bring the luminosity up to around 5*10^34/cm2/s and will possibly reach an integrated luminosity of 3000/fb at the end of that phase. CMS will therefore need a completely new, radiation resistant Tracker detector with trigger capabilities. I will also discuss the design choices and ongoing performance studies to explore options for the Phase2 Outer Tracker detector.

14:20 → 15:10 Operation and performance of the CMS pixel detector

The CMS tracker detector comprises two tracking devices utilizing semiconductor technology: the pixel and strip detectors. They are operating in a high-occupancy and high-radiation environment created by the beam interactions in the Large Hadron Collider (LHC). The pixel occupies the innermost region of the CMS detector providing the closest measurement points for charged particles produced in the LHC collisions. After introducing the detector, the presentation will describe the operational experiences collected during the first three years of LHC running. It will include operational challenges encountered during data taking. Some details will be given on the performance at high occupancy with respect to local observables, such as cluster properties and hit reconstruction efficiency, and on performance degradation due to radiation effects.
