| Summary:
Future strategic X-ray missions, such as the Advanced X-ray Imaging Satellite
(AXIS) and those targeted by the Great Observatories Maturation Program
(GOMaP), require fast, low-noise X-ray imaging spectrometers. To achieve the
speed and noise capabilities required by such programs, the X-ray Astronomy and
Observational Cosmology (XOC) Group at Stanford, in collaboration with the MIT
Kavli Institute (MKI) and MIT Lincoln Laboratory (MIT-LL), is developing
readout systems that leverage the high speed, low noise, and low power
consumption of application-specific integrated circuit (ASIC) devices. Here, we
report the energy resolution and noise performance achieved using MIT-LL AXIS
prototype charge-coupled device (CCD) detectors in conjunction with
Stanford-developed Multi-Channel Readout Chip (MCRC) ASICs. Additionally, we
present a new sampling method for simultaneous optimization of the output gate
(OG), reset gate (RG), and reset drain (RD) biases which, in combination with
new integrated fast summing well (SW) and RG clock operation modes, enables the
data rates required of future X-ray telescopes.
