Recent 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 کاملGyrotron 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 کاملdevelopment of feminist poetics in adrienne rich
اشعار ریچ، به عنوان اشعاری که همیشه در حال تغییر و دگرگونی هستند، تجسمی از رشد و دگرگونیِ انسان هستد. پایان نامه ی حاضر، با تمرکز بر روی مراحل سیر شعری ریچ از تغییری در دنیا به عکس هایی فوری از یک عروس، سپس به شیرجه به درون کشتی شکسته و در نهایت به صبری عجیب مرا تا اینجا آورده، به بررسی این مراحل در قالب نظر شوالتر در رابطه با سه مرحله ی پیشرفت ادبی زنان یعنی مرحله ی زنانه، زن گرا و زن محور می پ...
15 صفحه اولNotch 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 کاملNew trends in gyrotron development
Gyro-devices provide the highest CW or average power of microwaves in centimeter, millimeter and submillimeter wavelength ranges and therefore they are very attractive as microwave sources for many of applications such as plasma fusion, radiolocation, ion sources, telecommunication, technology, spectroscopy and some other. In last years an essential progress in the device development was demons...
