Abstract

This article surveys the impact of Homi Bhabha’s visio­nary initiatives in the area of electronics in India. We begin by surveying the early years at the Tata Institute of Fundamental Research, Mumbai and the Atomic Energy Establishment at Trombay that nucleated these activities and gave shape to Bhabha’s conviction on the importance of electronics for the growth of science and technology and nuclear energy in the country. We trace the evolution of indigenous technology in the areas of nuclear electronics, instrumentation and control systems for nuclear power plants, and assess their impact. This is followed by a review of the role of the Electronics Corporation of India Ltd in the growth of indigenous electronics in the country. We conclude with an appraisal of the current state of electronics in India.

Abstract

This article provides a case study of antenna control servo system development in the Department of Atomic Energy over the last five decades, starting with the pioneering efforts for Ooty Radio Telescope (1970) and Arvi Earth Station (1971). While tracing the evolution of technology, the challenges and motivations, we evaluate these efforts against the basic tenets espoused by Homi Bhabha and Vikram Sarabhai for the growth of science and technology in India, viz. self-reliance with commercial viability.

Abstract

The MACE telescope has recently been commissioned at Hanle, Ladakh, India. It had its first light in April 2021 with a successful detection of very high energy gamma-ray photons from the standard candle Crab Nebula. Equipped with a large light collector of 21 m diameter and situated at an altitude of ~4.3 km amsl, the MACE telescope is expected to explore the mysteries of the non-thermal Universe in the energy range above 20 GeV with very high sensitivity. It can also play an important role in carrying out multi-messenger astronomy in India.

Keywords

Gamma-ray astronomy, high energy radiative processes, non-thermal Universe, telescope.
