Abstract :
Summary form only given. An intense diagnostic neutral beam (IDNB) source is under development for use as a probe beam in upcoming large burning plasma experiments such as the international thermonuclear experimental reactor. The goal is to achieve a beam of deuterons of /spl sim/30 A/cm/sup 2/ at an energy of /spl sim/100 keV using an applied-Br, plasma-anode, extraction diode followed by a neutralizer region. This will provide up to several orders of magnitude more current density than conventional technologies. Initial tests have been made at 70 kV using flashover anodes to measure the uniformity, divergence, and current density as a prelude to testing of the neutralizer section - a critical portion of the IDNB source.
