Hamamatsu CCD Upgrade for the Gemini Multi-Object Spectrographs GMOS-S and GMOS-N: Results from the 2017 GMOS-N Upgrade and Project Completion Summary
Ground-based and Airborne Instrumentation for Astronomy VII(2018)
摘要
The installation of fully-depleted Hamamatsu CCDs in GMOS-N in February/March 2017 marked the conclusion of the CCD upgrade project for the two Gemini Multi-Object Spectrographs. The corresponding upgrade for GMOS-S was completed in June/July 2014, so that both GMOS instruments are now operated with a detector array of three fully-depleted Hamamatsu CCDs. We present results from the commissioning of the GMOS-N Hamamatsu CCDs and discuss their on-sky performance. We provide a comparison of the GMOS-N and GMOS-S detector parameters and summarize the main observing and data reduction strategies that apply to both detector arrays.
