The CIMPLE-PSI laboratory in India's northeast corner has been engaged over the last decade development of advanced experimental systems for controlled plasma fusion-relevant surface interaction (PSI) studies and material testing. device was commissioned recently, where a magnetized collimated helium beam is produced under steady-state conditions inside linear vacuum chamber, which can be made to interact with remotely placed targets, conditions. This paper reports on design, major sub-systems this performance integrated system. peak ion flux heat were measured as 1024 m−2 s−1 5.1 MW m−2, respectively; confirms that extreme ITER divertor-like parameters are successfully reproduced by simulation device. Steady-state operation electromagnet allowed prolonged leading very high fluence 0.3 × 1028 may enhanced further future. Tungsten samples exposed had led formation nanometer-sized tungsten fibre foam structures target. technique grazing incidence small angle x-ray scattering utilized measure average size bubbles remaining buried sample its variation depth from top surface.
