Imaging Tests of Short-Focus Lobster Eye Optics
Presenter: Vladimir Tichy
The grazing incidence X-ray optics called lobster eye provides wide field of view of the order of many degrees, for this reason it seems to be a convenient approach for the construction of future all-sky X-ray monitors. The prototype lobster eye module optics of focal length of 250mm manufactured in Rigaku Innovative Technologies Europe, s.r.o. (Czech Republic) is presented. Small mass and dimensions of this module allows it to be boarded on a nano-satellite. The performances of this lobster eye have been experimentally tested in quasi parallel beam full imaging mode using the 35 meters long X-ray beam-line of INAF-OAPA in Palermo (Italy). The X-ray images at the focal plane have been taken with a MCP detector at several energy values from 0.3 keV to 8 keV. The gain, the field of view and the angular resolution have been measured. Preliminary results are presented. Experimental results are compared to the results of the simulations.
