X-radiation from a region 4.0-11.0 mm above the anode of a 33kJ plasma focus device was spectrally 1.0-5.0 keV and temporally resolved. The plasma radiation during the first compression was found to correlate with a thermal plasma bremsstrahlung radiation in the temperature range 0.3-0.6 keV in pure deuterium. Additions of 1-4 argon and other high-z gases enhanced the soft continuum and produced intense line radiation about 20 nanoseconds after the first compression. Copper-zinc line radiation and continuum resulting from an ejected metallic cloud was produced about 150 nanoseconds after the initial compression. The angular photoelectron distribution for oblique, pulsed radiation incident upon a thin foil indicated a peak emission angle of about 30 degrees to about 50 degrees from the axis of incident radiation.
