Description
The ADITYA tokamak device is used to produce circular plasma for few
hundreds of milli-seconds. The edge physics study in this device is led to
significant contributions. The upgradation of this device is focused to
address issues relevant to heat removal capability at the plasma edge. This
requires to construct plasma equilibrium with divertor configuration. In this regard, additional pair of coils at the inboard and outboard are used to
construct plasma equilibrium. The inboard pair mainly creates the divertor
configuration while the outboard pair provides flexibility in increasing the
size of the plasma. This study has shown that plasma equilibrium with double null configurations can be produced for plasma current up to 100 kA and with plasma poloidal beta of 0.3. The limit on the plasma parameter is due to restriction on the allowable divertor coil current which
is limited to 150 kAt. The radial distance of divertor null point is kept
at least 3 cm away from the circular shaped vacuum vessel so that the
divertor configuration can be ensured.
