High-flux X-ray measurements with high-energy resolution and high throughput require the mitigation of pile-up and dead time effects. The reduction of the time width of the shaped pulses is a key approach, taking into account the distortions from the

In this paper results are presented for a novel charge loss correction algorithm that exploits the process of charge induction within compound semiconductor detectors. By detecting the residual induced signals in the pixels neighbouring an event, it
