Calculation of first wall protecting layer vaporization for ITS reactor chamber

In this paper we construct the model of interaction of X-ray radiation with the first wall of thermonuclear reactor chamber. This radiation is generated in the process of DT-burning in the FIHIF (Fast Ignition Heavy Ion Fusion) concept. The calculated results are presented for vaporization of the thin liquid protected layer and for the first wall loading in the frames of this model.
