The device


The YXLON FF35 CT is equipped with a YXLON 225 kV micro-focus directional beam tube and a YXLON 190 kV nano-focus transmission tube, which can be operated in two or four different power levels. Two different targets (tungsten and diamond) are available for beam generation. In this way, both millimeter-sized samples with high resolution and centimeter to decimeter-sized samples can be analyzed with high performance. The detector system from YXLON (Y.Panel 4343 CT CsJ, 2880 x 2880 pixels, pixel pitch 150 µm) offers the option of expanding the measuring field.
