Description
A monolithic active pixel sensor, Vanilla, with 512x512 pixels (25μm square)
has been fully characterised for the first time. Using PTC (Photon Transfer
Curve) measurements allowed for the calculation of the read noise, shot
noise, full well capacity and camera gain constant. Spectral response
measurements detailed the QE of the detector through the UV and visible
region. Optimisation of the sensor was made through variation between
readout modes (analogue and digital), frame rates, integration times and
on-chip biases and voltages. Further comparisons were made with a Vanilla
sensor with a thicker epi-layer (20μm, instead of the standard 14μm), to
help determine whether or not such sensors are - along with bio-medical
and space applications - suitable for use in particle physics experiments.
