The pCam6060 photodetecting system has been developed at SAO RAS based on the GSENSE6060BSI photodetector manufactured by GPixel (China) with a frame format of $6144 \times 6144$ active pixels and a pixel size of 10 micrometers. The readout speed reaches 11 fps. The back-illuminated detector has a wide spectral range of 200–1040 nm with a minimum quantum efficiency (QE) of 10% and a maximum sensitivity of 95% at 580 nm. The quantum efficiency in the near-infrared range is 58% at 850 nm. The pCam6060 system controller implements a mode of simultaneous image readout via two 12-bit video channels with different gain and their subsequent combination in the controller into a single frame with an extended 16-bit dynamic range. This method achieves simultaneously a low readout noise level (about 3 e$^{-}$) in the high-gain channel and a large dynamic range (full well capacity of about 100000 e$^{-}$) in the low-gain channel. Back-illuminated CMOS detectors, unlike front-illuminated devices, are not susceptible to the long-term preservation of the residual charge from previous exposures, which makes them suitable for recording faint objects in photometric long-exposure observing methods. Communication between the host computer and the camera is carried out via a fiber optic line at distances of up to 50 m. Video data are recorded on the computer hard drive in real-time. The pCam6060 photodetecting system is designed for astronomical applications and has a moisture-proof design.
