[en] A test facility to establish a 2 MW H neutral beam facility is under development at Institute for Plasma Research, Bhat, Gandhinagar. It consists of an 8 driver based cesiated RF ion source with a 1.8 m x 0.6 m extraction area, coupled to a 100 keV extractor and accelerator system. 6 MW of beam, 100 keV 60A, from the source is neutralized in a 4 channel 3 m long gas neutralizer followed by a 1 m long electrostatic residual ion dump to separate 2.4 MW of the ionic component of the beam. The remaining 3.6 MW of the neutral beam is characterized on a 2 arm calorimeter. The components are housed in a 9 m long ∼4 m diameter vacuum vessel connected to a duct and lined with 12 cryopumps to provide a total pumping speed of 10⁶ l/s. In addition to establishing multi ampere ion beams from large sources, the unique study on a total beam transport length of ∼20 m from the ion source will help to estimate beam losses due to direct interception, inherent beam divergence and mechanical misalignments, and re-ionisation due to neutral interaction with the residual gas. A 2^nd calorimeter helps characterize the beam at the end of flight path. Studies on the test bed also benchmark ITER requirements for the Diagnostic Neutral Beam (DNB). (author)
