Experimental High Energy Physics

The properties of nuclear matter at extreme conditions such as temperature and/or density are being studied in laboratories all over the world. The only way to create such extreme conditions in a laboratory is to use high energy accelerators and detect various types of particles produced in the relativistic nucleon-nucleon or nucleus-nucleus collisions either in fixed target or in the collider mode. The quarks and gluons, usually confined in the form of ordinary nuclear matter are supposed to get deconfined in these collision and create a new state of matter, consisting of deconfined quarks and gluons, called quark-gluon-plasma (QGP), depending on the temperature and/or density obtained in the collisions.

After several experimental activities at GSI (SIS), BNL (RHIC) and CERN (LHC), scientists working in this area of research have proposed a new facility, Facility for Antiproton and Ion Research (FAIR) at Darmstadt, Germany to study several things such as:

We here are working in development of a muon tracking system for the Compressed Baryonic Matter (CBM) experiment, involving Au+Au collisions using FAIR, to detect the muons coming out from the decays of the short lived particles created in the collisions. Due to very high rate of interations (107collisions/sec) and very high density of particles in the forward angle, the detector needs to be capable to handle high rate and have very good position resolution. Keeping these facts in mind, we are going to use Gas Electron Multiplier (GEM) as the detection technique for this tracking system.

We are also involved in the upgrade project for ALICE experiment at LHC. This includes R&D for an upgraded version of the Time Projection Chamber using GEM technology.
