We have developed a device which allows for a simultaneous measurement of both current density and energy density of an intense ion beam. The device is composed of a magnetically insulated Faraday cup and a micro-calorimeter; both are located in one magnetic system. A charge collector in the Faraday cup is also a calorimeter, the temperature of which is measured by a thermal resistor. A pair of permanent magnets (B = 0,4 T) is used at the device entrance in order to filter low-energy electrons accompanying the ion beam, providing an accurate measurement. The device was tested with an intense ion beam formed by a self-magnetically insulated diode. The experiments were carried out with the TEMP-4M accelerator operating in double-pulse mode: the first pulse is of negative polarity (300-500 ns, 100-150 kV), and this is followed by a second pulse of positive polarity (150 ns, 250-300 kV). The energy density of the ion beam was measured by the calorimeter and with the calculations made from the experimental values of the ion current density and accelerating voltage. The device was specially designed to study the formation of charge-exchange neutral atoms in diodes with a passive anode.
