Sunil Chitra

Sunil Chitra brings more than 20 years of accelerator radiation and health physics experience gained from various facilities in operational, R&D, regulatory and advisory roles. His expertise ranges from spectrometry for dosimetry with active and passive systems, FLUKA and MCNP Monte Carlo radiation transport codes and radiation protection calculations. He obtained his PhD from Mumbai University for his study on neutron time of flight measurements from heavy ion reactions and analysis with statistical nuclear reaction and phenomenological models. His other activities included spectrometry through few-channel under determined systems, development of detectors and techniques for neutron and special nuclear material detection to name a few. He was also involved in the study of the radiation safety aspects of several Accelerator Driven Systems (ADS), proton therapy machines, medical cyclotrons and installations in the nuclear fuel cycle. He was a visiting scientist at the PTB where he studied the response of a coincidence Tissue Equivalent Proportional Counter (TEPC) from 200 MeV/amu carbon ions interacting with tissue. He was also a scientific associate at CERN (European Organization for Nuclear Research) with the Compact Muon Solenoid (CMS) group where he estimated the long term activation of the components and the resulting residual dose rates for its HL-LHC (High Luminosity Large Hadron Collider) design upgrade, damage to the Si pixel detectors from near and distant beam halo from the LHC while also leading the radiation simulation group. He has been invited to deliver lectures/talks at various institutes/conferences, is a proponent of public outreach lectures on the effects of ionizing radiation and has taught accelerator health physics, radiation detection & measurement and radiation shielding courses. He has about 90 publications.
