ABSTRACT
A low-energy (2.3 kJ) plasma focus is operated in an enhanced Cu K[sub α] line emission mode. The emission is dominated by the interaction of electrons in the current sheath with the anode tip. The Cu K[sub α] line radiation of 0.4 J/sr is recorded in the side-on direction, which steadily increases in the end-on direction and attains the value of 0.8 J/sr. It is estimated about 40 J of energy is radiated as x rays, out of which 8 J is in the form of Cu K[sub α] lines in 4π geometry. The radiation yield represents a system efficiency of 1.7% for overall x-ray emission, and 0.35% for the Cu K[sub α] line. © 2001 American Institute of Physics.
