A West German National Magnet Laboratory is under construction at the Technical University of Braunschweig. The lab, which is scheduled for completion by the fall of 1970, will have four water‐cooled Bitter magnets. The field strength available is expected to be at least 175 kilogauss and may be as high as 200 kG. Power for the magnets will be supplied by a 5‐megawatt rectifying plant fed from the local ac network and delivering up to 500 volts dc. According to Edward Justi at Braunschweig this rectifying plant is believed to be the first of its kind, avoiding all rotating machinery. It uses silicon rectifiers, thyristors and several thousand transistors in a Darlington cascade to keep the current constant to 1 part in 105.
