Measurement of Electron Energy Distribution from X-Ray Diagnostics - Foil Techniques Used with the Hard X-Ray Camera on PBX-M

Author: S. von Goeler, R. Bell, S. Bernabei, et al.

A half-screen foil technique is used with the hard x-ray camera on the PBX-M tokamak to determine the energy distribution of the suprathermal electrons generated during lower hybrid current drive. The ratio of perpendicular to parallel temperature of the suprathermal electrons is deduced from the anisotropy of the bremsstrahlung emission utilizing Abel inversion techniques.
