| Popis: | A calorimeter system capable of DC biasing, consisting of a copper target plate, thermocouples (TC), and a copper electrical wire, has been newly assembled and applied for an experimental study of the cusp-type direct energy converter (CuspDEC) divertor concept. The calorimeter is designed to be capable of measuring the temperature of the target plate when the plate is electrically floated or biased. A beam of helium ions with an energy of 2–5 keV is used to test the calorimeter. The calorimeter successfully measured the heat flux and the measured value corresponded well to the theoretical expectations. In order to prove the deceleration of injected charges, which is a basic concept of the CuspDEC divertor, a DC bias voltage is applied to the target plate during beam exposure. As expected in the CuspDEC divertor concept, the suppression of the increase in the pate temperature by the bias voltage has been observed. |
