Abstract :
Two neutral beam lines have been built for coinjection and counterinjection into TEXTOR. The rated data for one beam line are 55 kV, 88 A (i.e. 4.8 MW) over 10 s for H2. The neutral injectors use cooled galvano-grids, cryopumps, and new solutions for the beam-dumps and power supplies. The components are described in detail. The measuring methods for the beam quality and the results are given, as well as some results from TEXTOR during neutral beam injection
