Annual review of the Institute of Plasma Physics, Nagoya University, for fiscal 1975

The fiscal year of 1975 is the second year of the five-year program, which consists of the six major experiments, namely, the JIPP T-II project, the high-beta experiment, the rf plugging experiment, the research for relativistic electron beam, the hot electron plasma experiment and the experimental study of laser-plasma interaction. The JIPP T-II device, a hybrid system of stellarator and tokamak, is in the assembly stage at the end of this period. Preparations for rf heating and neutral beam injection and also for diagnostics are in progress. The design study of a new device RFC-XX for the rf containment experiment has been performed and its construction has started. In the program of high-beta experiment, the design study of the symmetric torus being capable of adiabatic compression has started and also the technological test on the MJ bank system is in progress. The installation of high current electron beam and the equipment of high power microwave for ECRH are planned. A new system for laser plasma production by utilizing an ''on-line computer control'' technique has completed and a freely falling deuterium pellet can be successfully captured by a high power laser. In parallel with those experimental programs, experiments on basic plasma physics and theoretical works were carried out actively. These works were carried out under the cooperative research program with many experimentalists and theoreticians in this country and also international collaborations with visiting foreign physicists.
