Neutron fluctuation measurements on TFTR
Description
The author reports measurements of fluctuations in the neutron yield made on TFTR with plastic scintillators. Light from the scintillators is coupled through fiber optic cables to photomultipliers operated in current mode. Discrimination against hard X-rays is accomplished through comparison with the signal from a ZnS(Li6) scintillator. These measurements are useful in studies of deuterium pellet deposition, of the acceleration of beams ions during major radial compression, and of MHD instabilities. To study the mode numbers of the instabilities, detectors are situated at different poloidal and toroidal positions. Techniques for measuring the neutral beam density profile and Qequivdt using neutron fluctuation measurements during pellet injection are proposed
