A 60 kV neutral lithium diagnostic beam probes the edge plasma of JET for the measurement of electron density profiles. This paper describes recent enhancements of the diagnostic setup, new procedures for calibration and protection measures for the lithium ion gun during massive gas puffs for disruption mitigation. New light splitting optics allow...
The study of target injection, detection, measurement of laser focal point, and laser beam steering have started under co-research in Japan. The smooth-bore gas gun is developed for accurate injection. The applications of divergent laser beam and Arago spot are described for accurate measurement of target position and laser focal point. Magnetic lens for target trajectory adjustment by centerin...

Twenty rounds vere fired with the 15 gr. Modified M22 primers. A mean deviation of 2 f/s or an estimated probable error in velocity of 1.5 f/s was obtained. An explanation of this low dispersion in velocity is tentatively offered. Authority was ohtnin^d to fire a 20 round uniformity series in a 75 mm Gun Mod. 1G97 using charges of S.P. FNH, powder lot 5530, ignited with a 15 gr. Modified M22 pr...
