UZH CCD Testing Setup (DAMIC-M / DAMIC)
This TWiki page is devoted to the functional description of the CCD testing setup at the Physics Institute of the University of Zurich and its associated hardware/software. A description of the cryostat, the associated electronics, and the instrumentation infrastructure is provided. The setup is based on the AlpineCube cryostat apparatus, an in-house design by the University of Zurich's Peter Robmann, and is currently located in building 36, floor H, room 78.

For storage, a 4 x 4TB hot-swap HDDs array, configured in RAID10 mode is used with the on-board intel RAID controller (Intel Rapid Storage Technology). This setup enables simultaneous writing to two hard drives (RAID1) and data mirroring to another two (RAID0). This configuration enhances writing speed and maintains a constant backup of the entire system. Each of the four 4TB hard drives contributes to an effective storage capacity of 8TB.
The system does not support UEFI, and access to full storage capacity is limited to operating systems supporting GPT architecture (>2TB volumes). The lack of UEFI limits Windows to MBR-only versions, and UNIX-type operating systems are recommended. For the operating system, Ubuntu 20.04.6 LTS was chosen due to its compatibility with LabVIEW (Q3 2022), the LTA and our image acquisition software. The default package manager is apt, while rpm is also present. For further information about our server please read the following pages.
There are multiple Software's, programs and other files installed on this server a full list can be found following this link: Software
Our instruments can be loosely grouped into 5 different groups:
All implementation of CCD readout systems have a common architecture and comprised of four common functional elements: The picture below shows the generall outline of a CCD.
Three different readout options for skipper CCDs exist. The first is the leach system, developed by: Astronomical Research Cameras. The second option is a Low Threshold Acquisition (LTA) system, developed by Fermi lab for the Oscura experiment. The third option is using the ACM board, developed by the University of Chicago and LPNHE specifically for the DAMIC-M experiment. Information for each system are available in the following pages:
