BARC is developing technologies for a high current low energy proton accelerator, which includes a 3MeV RFQ. As part of this, a 400 KeV prototype deuteron RFQ has been planned. This RFQ will also be utilized later to replace 14 MeV neutron generator at BARC. In this paper we are presenting Thermo-structural analysis of RFQ and features such as RF Coupler, Tuner, Vacuum port etc. This investigation will lead to design of local cooling schemes of these components. Parametric studies are also included in this paper. Feasible Cooling schemes which meet cooling requirements of components will also be discussed.

| The scanner is an important tool for accelerator based material science research. For high energy (~100 MeV) ion beam scanner has to be magnetic one. Major problem faced with magnetic scanner is its high inductance which causes large impedance to the a.c. power supply used to energise the magnet. We have designed a magnetic scanner keeping attention to minimise its inductance. The scanner is composed of two independent H-type dipole magnets which are fed by saw tooth pulses. It can scan over an area of 25 mm x 25mm at a distance of 1 metre. The power supplies for this scanner have also been designed. These are bipolar, wideband, high speed amplifirs that can reproduce complex waveform without any distotion. The ratings are 60V, 50A operating at 50Hz for x-scanner and 5V,70A at 0.2Hz for y-scanner. Design and performance of the scanner magnet and power supplies will be presented. |
