MX340-XFEL


A very large area, high speed X-ray detector with a central 5mm wide tunnel through the imaging area, exiting in the back of the detector. This tunnel enables beam diagnostics or further experiments behind the detector. With a 340 x 340mm² square active area, this detector consists of 16 frame-transfer CCD modules, tiled without gaps in the imaging area. Full resolution is 7680 x 7680 pixels

Category: .
Description
This 340mmx340mm square X-ray area detector with beam tunnel has several specialized modes. Besides the standard mode described in the specs and parameter sections, Turbo, Low-Noise and High Dynamic Range (HDR) modes are also user controlled.
