Assessment of the ITER high-frequency magnetic diagnostic set
The ITER high-frequency (HF) magnetic diagnostic system has to provide essential measurements of MHD instabilities with vertical |δBMEAS/BPOL| ~ 10 (~1 G) for frequencies up to 2 MHz to resolve toroidal mode numbers (n) in the range |n| = 10 to |n| = 50. A review of the measurement requirements for HF MHD instabilities in ITER was initiated during the TW4 work-program and led to significant int...
متن کاملDesign of the ITER high-frequency magnetic diagnostic coils
This paper is an overview of work carried out on the design of the ITER high-frequency magnetic diagnostic coil (HF sensor). In the first part, the ITER requirements for the HF sensor are presented. In the second part, the ITER reference design of the HF sensor has been assessed and showed some potential weaknesses, which led us to the conclusion that alternative designs could usefully be exami...
متن کاملHigh Frequency Amplitude Detector for GMI Magnetic Sensors
A new concept of a high-frequency amplitude detector and demodulator for Giant-Magneto-Impedance (GMI) sensors is presented. This concept combines a half wave rectifier, with outstanding capabilities and high speed, and a feedback approach that ensures the amplitude detection with easily adjustable gain. The developed detector is capable of measuring high-frequency and very low amplitude signal...
متن کاملPrototyping a High Frequency Inductive Magnetic Sensor Using the Non- Conventional, Low Temperature Co-Fired Ceramic Technology for Use in ITER
The ITER high-frequency (HF) magnetic sensor is currently intended to be a conventional, Mirnovtype, pick-up coil, designed to provide measurements of magnetic instabilities with magnitude as low as |δB|~10G at the position of the sensors, and up to frequencies of at least 300kHz. Previous prototyping of this sensor has indicated that a number of problems exist with this conventional design, wh...
