Description
Electron Multiplying CCDs (EMCCDs) are a relatively recent class of devices that have found a variety of applications ranging from astronomy to microbiology. The key distinction from a conventional CCD lies in the addition of a multiplication register, which uses high electric fields to increase signal size through the process of impact ionisation. The result is a highly sensitive device, capable of single photon detection at high readout speeds. As such, EMCCDs have many applications where high sensitivity and high frame rate are a priority, including low light spectroscopy and LIDAR. Utilisation in future applications and adoption within a space environment hinges on further mitigation of undesirable device characteristics, including Clock Induced Charge (CIC) and the observed decrease in gain as a function of device age (the “ageing” process). Here we present a study aimed at further alleviating these issues through state-of-the-art simulations and laboratory measurements from sample devices.
