Abstract

The next generation of Radial Velocity Spectrometers for 8 metre class telescopes will require very high resolution spectroscopy in the near infrared 1-2.5μm regime. One of the main engineering goals for such an instrument design is to readout at high speed, multiple windows, which are concurrently imaging bright reference arc lines whilst also integrating very faint source spectra on the rest of the detector. The Hawaii-1RG/2RG readout multiplexers offer a programmable window readout mode which allows non-destructive readout of multiple regions which are programmable in any size and location on the array. We present results from the characterisation of an engineering grade H1RG detector using an SDSU III controller and the effects of the multiple window readout, if any, on the noise and cross-talk performance of the rest of the detector. The detector performance results will also include quantum efficiency measurements in J, H and K pass bands, dark generation, noise, full well, linearity, inter-pixel capacitance and persistence.
