Abstract

PANIC¹ , the PAnoramic Near-Infrared Camera for the Calar Alto Observatory in Spain, was successfully commissioned in late 2014 with a mosaic of four 2K x 2K HAWAII-2RG arrays covering a field of view of approximately 30 arcmin at the 2.2 m telescope. Unfortunately, two of its science detectors suffered from extreme degradation² along the years of operation making the instrument unsuitable for science observations. In the light of new technologies and constant innovations, it was decided to upgrade the instrument with a monolithic state of the art 4K x 4K HAWAII-4RG array. With as minimum mechanical and optical impact as possible for the instrument, the MPIA is the responsible institute for the challenging upgrade. Besides presenting the results of the initial operation of the HAWAII-4RG array in 64-Channel mode, the newly in-house designed detector mount will also be highlighted. In order to take as much advantage as possible of the new detector readout capabilities, and thanks to the modularity and flexibility of the in-house readout electronics, all 64 channels of the detector are read out in parallel. This allows for shorter integration times, which is very advantageous for a wide field imager with high background conditions.
