Founded in 1947 by Dr. Vikram A. Sarabhai, the Physical Research Laboratory (PRL) had a modest beginning at his residence, the RETREAT, with research on Cosmic Rays. The Laboratory was formally established on November 11, 1947, in the M. G. Science College, Ahmedabad, with support from the Karmkshetra Educational Foundation and the Ahmedabad Education Society. The Administration endeavours to facilitate scientific research by providing support at all levels. These range from general administrative matters to infrastructure support including civil, electrical and air conditioning. The Accounts Section handles all financial matters and the Purchase Section facilitates procurement of scientific and other goods. Our research programmes involve the applications of stable and radioactive isotopes to characterize and determine time scales of processes occurring in the early solar system. The aim is to study the origin and evolution of the solar system with focus on inner planets. All Sections are managed by professionals and most of the works are carried out using "Computerised Working in Administrative Areas" (COWAA) software developed inhouse specifically for ISRO Centers. The academics in the Physical Research Laboratory are as follows Astronomy & Astrophysics Division Atomic, Molecular & Optical Physics Geosciences Planetary Sciences Space & Atmospheric Sciences Theoretical Physics Udaipur Solar Observatory Hari Om Ashram Prerit Sr. Scientist Award – 2012: The Physical Research Laboratory invites nominations for the Hari Om Ashram Prerit Senior Scientist Award instituted to commemorate the Birth Centenary of Pujya Shri Mota, Founder of the Hari Om Ashram, Nadiad. The award is presented to an eminent Indian Scientist for his/her innovative and outstanding contributions in Science & Technology and is given once every two years. The award consists of a Silver Plaque, a Citation and a Cash Prize of â¹ 2,00,000/-.
