Research, design and development activities on high power pulsed rf/microwave systems and test facilities for particle accelerators

Several high power S Band microwave systems in the peak power range from 2 MW to 6.5 MW and mean power upto 25 kW along with associated waveguide components, pulse power technology were developed in house at RRCAT. These systems have been used extensively in the development of particle accelerators in the country. Several test facilities were developed in house and supplied to tube R and D labs for development, conditioning and evaluation of microwave tubes indigenously under collaborative efforts. RRCAT has also taken up establishing high power test facilities for advanced accelerators. For such used design and development of 45 MW peak power S Band test facility as well as energy doubler scheme is underway. A 1.3 MW pulsed test stand at 352.2 MHz was also successfully designed and developed to qualify devices, subsystems and components developed in-house. The present paper will describe the research, design and development efforts towards the high power pulsed RF/Microwave systems, test facilities and components. The results and performance of these developments are reported. (author)
