Notes:
Soft x-ray Bremsstrahlung emission of suprathermal electrons is commonly used for electron temperature measurements in plasma experiments. A difference between suprathermal and bulk electron distributions results in a discrepancy between the measured and real electron temperatures. This is considered as a diagnostic demerit. On the other hand, this discrepancy carries specific information about factors disturbing the electron distribution. One of them is an electric field driving the electrons along a magnetic field. A way of measuring the longitudinal electric field using suprathermal electron Bremsstrahlung emission has been proposed and analyzed in the article. The plasma current density is found from Ohm's law. © 2001 American Institute of Physics.
