Indus-1

Indus-1. It is a first-generation synchrotron radiation source located at the Raja Ramanna Centre for Advanced Technology in Indore, India. Commissioned in 1999, this national facility provides a critical tool for research in materials science, biology, and chemistry. Operated under the aegis of the Department of Atomic Energy, it marked a significant milestone in India's scientific infrastructure.

Overview

Indus-1 serves as a dedicated source of synchrotron light for the Indian research community, enabling experiments that require intense X-ray and ultraviolet radiation. The facility is part of a larger complex that includes the more powerful Indus-2 synchrotron. Its establishment was driven by the vision of scientists like A. Kakodkar and institutions such as the Bhabha Atomic Research Centre to advance condensed matter physics and related fields. Researchers from across the country utilize its beamlines for non-destructive analysis of various samples.

Technical specifications

The machine accelerates electrons to an energy of 450 MeV using a microtron as its injector. It has a compact circumference of 18.96 meters and employs conventional bending magnets to generate synchrotron radiation. The critical wavelength of the emitted photons is around 61 Å, placing its spectral output in the vacuum ultraviolet and soft X-ray regions. Key subsystems include a radio frequency cavity for beam maintenance and a complex ultra-high vacuum system to minimize beam scattering.

Scientific applications

The beamlines at this facility support diverse investigations in surface science, molecular spectroscopy, and protein crystallography. Experiments often focus on the electronic structure of novel materials like high-temperature superconductors and nanomaterials. It has been instrumental in studies conducted by organizations like the Indian Institute of Science and the Tata Institute of Fundamental Research. Research areas also extend to lithography for microelectromechanical systems and analysis of archaeological artifacts.

History and development

The project was conceived in the late 1980s, with formal approval coming from the Government of India in 1990. Design and construction were spearheaded by the Centre for Advanced Technology, which later became the Raja Ramanna Centre for Advanced Technology. Critical collaboration involved entities like the Bhabha Atomic Research Centre and international consultations with facilities such as the Synchrotron Radiation Center in the United States. The first stored beam was achieved in 1999, following milestones like the commissioning of its microtron injector.

Operational details

The facility typically runs in scheduled cycles for user experiments, with beam time allocated through a peer-review proposal system. Operation and maintenance are managed by a team of scientists and engineers from the Raja Ramanna Centre for Advanced Technology. Upgrades over the years have included improvements to beam stability and the addition of new experimental stations. It functions as a vital training ground for accelerator physicists and forms an integral part of the Indus Complex alongside the larger Indus-2 ring.
