Abstract
It is nowadays evident that imaging and/or tomographic X-ray diagnostics will be based on photon counting mode, rather than on current mode (SBD or AXUV diodes). In addition the advantage of energy discrimination is meanwhile well established. In the last ten years gas detectors (GEM) allowed us to investigate this new approach. On the other hand, the new generation of C-MOS imagers allows a higher pixel density but with greater limitations in active area, time resolution and flexibility. The C-MOS imager Medipix-2 was characterized in laboratory as 2-D Soft X-ray imaging detector to assess its potential for imaging in magnetic fusion plasma experiments.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
