Abstract
The present status of the main components of the TJ-II Electron Bernstein Waves (EBW) heating system are presented. The O-X-B scenario has been chosen for first harmonic (28Â GHz) heating. One 300Â kW, 100Â ms gyrotron has been checked and is ready for installation. The design of a new high voltage power supply unit is finished. The microwave power will be transmitted by an oversized corrugated waveguide. Two ellipsoidal mirrors optimise the gaussian beam parameters at the input of the waveguide and two corrugated ones get the required polarization. A movable internal mirror is needed to accomplish the restrictive launching conditions. The present cooling system of the ECRH system is being upgraded to cool the 28Â GHz-complex. The start of the experiments is scheduled for the end of 2005.
