Spectroscopic measurements have been made of impurity radiation from coaxial sources used to produce spheromaks at Los Alamos. Some of these measurements were viewing the interelectrode region of the source. They show Doppler shifts implying impurity transport for low-Z impurities but not for metallic impurities. In others the relative emission of various lines from the spheromak in the VUV, quartz UV, and optical spectral regions are compared for various source operating parameters. Evidence for the control of impurity production is presented, and a descriptive model is proposed which explains aspects of the transport of impurities from the source into the spheromak.
