Gyrotron for ITER
Recent megawatt gyrotron experiments at MIT have achieved record powers at 170 GHz. Single mode emission with a peak output power of 1.5 MW and an efficiency of 35% has been measured. The experiment is based on a resonant TE28 ,8 ,1 cylindrical cavity situated in a 6.7 T magnetic field. Microwaves are generated in the cavity by an 83 kV annular electron beam produced by a triode-type magnetron ...
متن کاملRecent activities of ITER gyrotron development in QST
QST is committed to the development of high power RF power sources (or gyrotrons) for plasma heating in fusion devices. Our main activity is the development of 170GHz gyrotron for electron cyclotron resonance heating and current drive (EC H&CD) system of ITER project which requires 20 MW of power injection into fusion plasma. In ITER, 24 sets of 1 MW gyrotrons are planned to be installed of whi...
متن کاملNotch Filter Options for ITER Stray Gyrotron Radiation
ITER will have multi megawatt gyrotron systems at 170, 120, and potentially at 60 GHz for ECH, current drive, NTM control, start up, and CTS diagnostics. The ITER environment will therefore have significant background levels of stay radiation at these frequencies that can pose a problem to a number of diagnostic systems. Several deep, narrowband reject filter approaches have been examined. Thes...
متن کاملDevelopment and operation of an ITER relevant inspection Robot
Robotic operations are one of the major maintenance challenges for ITER and future fusion reactors. In particular, in vessel inspection operations without loss of conditioning will be mandatory. In this context, an Articulated Inspection Arm (AIA) has been developed by CEA within the European work programme framework, which aims at demonstrating the capabilities of a multi-purpose in-vessel Rem...
متن کاملQualification Tests and Facilities for the ITER Superconductors
All the ITER superconductors are tested as short length samples in the SULTAN test facility at CRPP. Eighteen TF conductor samples with small layout variations were tested since February 2007 with the aim of verification of the design and qualification of the manufacturers. The sample assembly and the measurement techniques at CRPP are discussed. Starting in 2010, another test facility for ITER...
