Accelerator Physics

By Prof. Amalendu Sharma, Prof. Rajni Pande, Prof. Pitamber Singh   |   IIT Bombay
Learners enrolled: 1996
ABOUT THE COURSE: Accelerators have an important role both in basic and applied research, eg., medical science, industry, national security, environmental science etc Electron accelerators are built for food irradiation etc and as Synchrotron Radiation Source for material science research.
Depending on how particles are accelerated, accelerators are categorized as DC accelerators, Linear and Cyclic accelerators and Laser-Plasma Accelerators. Today, accelerators in the energy range of keV to TeV have been designed, built and used. In order to design, operate and utilise them efficiently, the physics of the accelerators should be well understood. In this course, physics of DC, Linear and Cyclic accelerators will be discussed and high energy accelerators will be briefly reviewed.

INTENDED AUDIENCE: Ph. D. Students and researchers, Hospital Doctors and Staff and Industry people and Defence personnel.

PREREQUISITES: B.Sc in Physics or B.E, The course is a stand-alone course for application of accelerators in research in Physics, medical sciences, industrial applications and national security.

INDUSTRY SUPPORT: Several academic institutions, industries and defence departments will be interested. Many accelerators are in operation in industry for food irradiation and for medical treatment in hospitals.

Instructor bio

Prof. Amalendu Sharma

IIT Bombay
Prof. Amalendu Sharma graduated from the BARC Training School, RRCAT, Indore in 2001. He has worked on the relaxed optics for ease commissioning of 2.5 GeV Indus-2 synchrotron radiation source at RRCAT and participated in commissioning exercises of Indus-2. Dr Sharma also carried out studies on the inclusion of harmonic sextupole magnets in Indus-2 to improve the beam lifetime for low emittance, high brightness optics. He was the convenor of the team responsible to increase the beam current at in Indus-2 and shaping it in the routine stable operation mode. He also participated in the optics design of an electron beam transport line to compress the bunch length for CTF3 project at CERN under the DAE-CERN collaboration and on this work, he obtained his PhD, in 2014 by HBNI. Presently, Dr Amalendu Sharma is leading the beam dynamics activities for designing the 1 GeV Proton Accumulator Ring of Indian Facility for Spallation Research. He is also contributing to the optics design of energy filtering and beam delivery system of radiation processing facility development at RRCAT, Indore. Dr Amalendu Sharma has been teaching Accelerator Physics in BARC Training School at RRCAT, Indore for the last 14 years. He also took classes in the Orientation Course on Accelerator and Laser (OCAL) in RRCAT, in which M.Sc and B.Tech students participated.
