A 50 kW RF based plasma power supply has been designed for incineration of Low and intermediate level radioactive solid waste with activity of the order of 10 mR. Power supply is class C tube based amplifier. Specification has been decided based on CFD simulation of incinerator facility at BARC and plasma sustainability. This paper describes design of tube based 50 kW power amplifier from calculations...
Radio frequency (RF) structures that are part of accelerators and energy sources, operate with sinusoidally varying electromagnetic fields under high RF energy. Here, RF breakdown and multipacting take place in RF structures and limit their performance Electron field emission processes in a RF structure are precursors for breakdown processes. RF breakdown is a major phenomena affecting and causing...
A high power RF system has been designed, developed and tested for 60 kW power, both in CW and pulse mode. Its many subsystems of stringent specifications have been developed for it. Further, this system has been successfully coupled to radio frequency quadrupole (RFQ) accelerator via rigid coaxial transmission line. This paper describes the design and development of high power RF system and its power...
This paper discusses details of an ‘Interlock and Protection System for 1 MW Klystron Radio Frequency (RF) System of LEHIPA’ which includes control, interlock and protection of high power DC supplies and other auxiliary systems connected to a 1 MW Klystron RF System. This system is exposed to high Radio Frequency Interference from the high power amplifier and other connected systems. Therefore it...
Bhabha Atomic Research Centre (BARC) Mumbai is developing Low Energy High Intensity Proton accelerator (LEHIPA) of energy 20 MeV, 30 mA. LEHIPA comprises of Radio Frequency Quadrupole (RFQ) accelerator (3 MeV), 10 MeV Drift Tube Linac (DTL) and 20 MeV Drift Tube Linac (DTL). As per the accelerator physics design, RFQ and DTLs require about 2.4 MW of total radio frequency (RF) power. Each accelerating...
As a part of ADS program a proton accelerator (20 MeV, 30 mA) and its high power RF systems (HPRF) are being developed in BARC. This paper explains design details of this klystron based HPRF system.
