Dynamic-range limitations of intensified CCD photon-counting detectors

Fordham, J. L. A.; Moorhead, C. F.; Galbraith, R. F.

The bright limit to the dynamic range of intensified CCD photon-counting detectors is governed by coincidence losses. In this paper a theoretical analysis of the loss mechanisms is carried out and verified using laboratory data. For applications where the input source is stable, such as star field imaging from space, the theoretical dynamic-range …

High time-resolution spectroscopic imaging using intensified CCD detectors

Much, R.; Kawakami, H.; Fordham, J. L. A. +2 more

The micro-channel plate intensified CCD photon counting detector developed at University College London has been upgraded to allow time-resolved spectroscopic optical data to be acquired on periodical sources such as pulsars. First observing trials have been carried out, acquiring spectroscopic data on the Crab pulsar. The detector was phase locke…
