Using LVIC in current mode for energy spectrum reconstruction: experiments and validation

Résumé

In tokamaks with Tungsten plasma facing components such as ITER, pollution of the plasma by heavy impurities is a major concern as it can lead to radiative breakdown. A diagnostic allowing reconstruction of the impurity distribution is thus of high interest. The radiation emitted by such impurities is mainly composed of soft X-rays (SXR) in the [0.1, 100] keV range. Due to the ITER radiative environment, in particular during high D-T power phase classic X-ray detectors such as semiconductor diodes might be too fragile and are thus not viable. Instead, advanced detectors (such as gas-filled detectors) are nowadays considered. The Low Voltage Ionization Chamber (LVIC) is one of the most promising candidate for X-ray measurement during the ITER nuclear phase [1]. A complete model of the detector recently developed at IRFM [2] now requires experimental validation.
