    "abstract": "An Alvaretz-type DTL, to accelerate the H- ion beam from 3 to 50 MeV, is\nbeing constructed as the injector for the JAERI/KEK Joint Project. The\nfollowing components of the DTL have been developed: (1) a cylindrical tank,\nmade by copper electroforming; (2) rf contactors; (3) a pulse-excited\nquadrupole magnet with a hollow coil made by copper electroforming; (4) a\nswitching-regulator-type pulsed-power supply for the quadrupole magnet.\nHigh-power tests of the components have been conducted using a short-model\ntank. Moreover a breakdown experiment of the copper electrodes has been carried\nout in order to study the properties of several kinds of copper materials.",
