» Capabilities of Medipix2 Device as Detector for Lobster Eye X-ray Optics
Presenter: Vladimir Tichy
The hybrid semiconductor pixel device Medipix2 is a single particle counting detector of X-ray radiation from approx. 3keV of energy. It has small dimensions (256 x 256 square pixels with pitch of 55 microns) and low power consumption. This makes the detector suitable for space applications, eg. as a detector for telescope with a lobster eye optics. Lobster eye is a type of an X-ray optics using two perpendicular sets of mirroring plates for focusing. This optics provides wide field of view. The results of the preliminary experiments with the Medipix2 detector and the lobster eye optics are presented and discussed. Tests are performed with X-rays of energy about 8keV. X-ray source is imaged from variant positions. Basic parameters as field of view and the spatial resolution are measured. Image distortions as function of source position are described. This work has been carried out within the Medipix2 collaboration.
