“ Leach Controller ”
The focal plane is controlled via a SDSU Gen-II Controller designed and built by Bob Leach of Astronomical Research Cameras. It also uses a set of pre-amp cards and co-adder boards from IR-Labs. The combination allows the entire 2048x2048 Hawaii-II array to be read in about 0.1 second. The Gen-II controller is highly versatile. In particular, custom waveforms for each detector array can be downloaded to the controller using a computer interface. This allows for selectable regions of interest, on-chip binning, etc. Initial tests and characterization of the controller are now complete.
