DIAGNOSTICS PROPOSAL FOR T-15 FUSION-RESEARCH BY MEANS OF CHARGED PRODUCTS AND NEUTRONS

A majority of the planned fusion product diagnostics for the T-15 toka mak are described. These include a few dozen silicon diodes to detect escaping charged fusion products with high energy resolution. They wil l resolve the charged particle fluxes in radial, pitch angle, energy a nd time dependences. In addition, measurements of DD neutron birth pro files are proposed to be carried out using two independent systems - a bubble chamber and a 'sandwich' radiometer that have not been used in tokamaks to date. A new method of plasma current profile measurement is suggested, based on the detection of 'test' alpha particles emitted by radioactive sources at the vessel wall.
