Fig. 2: EIGER-iLGAD.
a Picture of a 4 × 4 cm2 inverse-LGAD sensor bump-bonded to an EIGER ASIC, mounted on a vacuum-compatible flange. b Image of the far-field diffraction from a Frenel Zone Plate focusing optics projected on the detector surface acquired with a 550 eV photon beam (single frame with 1 s exposure time). Additional diffraction and scattered X-rays are visible in the background. The set threshold corresponds to ~480 eV. Fewer than 1% noisy pixels have been masked out.
