ABSTRACT
A fast two-dimensional soft X-ray camera using silicon photo diode array is being developed in order to investigate high frequency MHD instability with high mode number. The advantage of the adopted diode is a large sensor area of 10 mm × 10 mm and small diode capacitance which enable us to measure signals with the short response time. The characteristic of the prototype is summarized as follows Channel number is 6 × 8 = 48, detection range 1â¼10 keV, the spatial resolution 128 mm at the plasma location, and frequency range DCâ¼100 kHz. Synthetic image of the prototype in the Large Helical Device is estimated by using perturbation model of MHD mode.
