ADITYA is a medium size tokamak installed at the Institute for Plasma Research in India. It has a major radius of 0.75 metres and a minor radius of 0.25 metres. The maximum field strength is 1.2 tesla produced by 20 toroidal field coils spaced symmetrically in the toroidal direction. It is operated by two power supplies, a capacitor bank and the APPS (ADITYA pulse power supply). The typical plasma parameters during capacitor bank discharges are: Ip ~30 kA, shot duration ~25 ms, central electron temperature ~100 eV and core plasma density ~1019 m-3 and the typical parameters of APPS operation is ~100 kA plasma current, ~ 100 ms duration,central electron temp. ~300 eV and ~3x1019 m-3 core plasma density.
