Soft X-ray measurements of μS-E-beam-heated plasma

The soft X-ray and VUV measurements on the GOL-3 device are described. The region of plasma VUV emission is shown to coincide with the calculated E-beam cross-section. This indicates the beam stability during its pass through the long magnetized plasma column. The data on plasma radiative loss in different spectral ranges is presented. The suprathermal electrons with average energy above 10 keV are shown to exist in plasma. The power of soft X-ray emission from the bulk plasma is estimated.
