Diagnostic Developments for the Mast Spherical Tokamak
MAST1 is a relatively new spherical tokamak (ST) with plasma cross-section and parameters comparable to those of ASDEX-U and DIII-D but at much lower field (0.5T) and aspect ratio (∼1.3). The plasma is heated with neutral beams and two 60GHz RF schemes (ECRH and, under development, electron Bernstein wave heating). The aims of MAST are to contribute to mainstream tokamak physics, for ITER, and to test the potential of the ST in its own right. Diagnostics for MAST combine new and conventional approaches to match the plasma and machine layout. Systems must accommodate a flexible physics programme and an unusually wide range of plasma configurations.
