Novel lobster eye and Kirkpatrick Baez modules based on multifoil technology: design, assembly and tests

Abstract

We present very preliminary results the design, assembly, and tests of new Lobster Eye (LE) and Kirkpatrick Baez (KB) modules based on Multi Foil Optics technology (MFO). The LE X-ray optics is a wide field of view (FOV) optics type Lobster Eye (LE) with a short (400 mm) focal length (suitable for CubeSat application) based on Schmidt design. The 2D LE optics consists of two orthogonal sub-modules of flat smooth reflective foils and each sub-modules focuses in one direction. The key parameters (the FWHM, the FOV (Field of view), and angular resolution, effective area) of the 2D LE optic were measured with different detectors. The advantage of MFO LE is that for off-axis points the angular resolution is preserved throughout the FOV, as demonstrated by measuring. There is a combined detector system that includes two detectors - Timepix3 Quad and spectroscope. The benefit of the combined detector system was demonstrated in the real measurement. Moreover, a new generation multiple arrays module of 2D X-ray KB optics with long f (nearly 6 meters) based on multi-foil silicon assembling technology was designed, manufactured, and tested in optical light and in X-rays at the Panter facility and the preliminary results will be also presented and discussed.
