The problem of the calibration of SIMBOL-X X-ray telescope
Abstract
One of the main problems concerning the implementation of the telescope with a long focal length is related to the calibration tests. Soft X-ray (0.1 - 10 keV) telescopes with good imaging performances like e.g. XMM, have been so far calibrated by full illumination with X-rays. However, in the case of Simbol-X, a number of different issues have to be solved, as e.g. the area loss due to the finite source distance in presence of a long focal length and the different X-ray reflectivity response from the parabolic section of the multilayer-coated mirrors with respect to the hyperbola. In this paper we will propose a possible configuration to be adopted that would satisfy the mission requirements.
