Description

The Multiple Amplifier Sensing CCD (MAS-CCD) is a low-noise silicon imager designed to reduce the readout time required to reach the single-photon counting regime by distributing non-destructive charge measurements across multiple Skipper output stages. The MAS architecture, however, rapidly increases the number of video channels that must be instrumented, creating a significant scalability challenge for the readout electronics. In this talk, we present recent results obtained with a 16 output device that was extensively characterized, demonstrating the single-photon resolution, readout performance, node removal inefficiency, and new faster readout regimes. Also, we present the device operating under a real astronomical environment. We also present ongoing readout developments aimed at scaling the instrumentation of large format devices, such as a dedicated ASICs.
