FastCCD Startup Process

Cautions

Before running the FastCCD, check the state of the power supplies and cooling. The FCRIC and timing configuration can be modified live, however bias values should not be modified without turning off camera bias and clocks; otherwise damage to the sensors may result.

Setup the FastCCD

The FastCCD can be initialized and checked from fastcameraATCA1.dhcp.lbl.gov when coming online.

  • Connect to fastcameraATCA1.dhcp.lbl.gov via SSH and start the VNC server using the following commands

      vncserver -list
      shows last vnc process; the process shown may actually have ended, but you can restart it with below commands

  vncserver -kill :11
      kills the vnc server on window 11

  vncserver :11 -geometry 2400x1400
      starts a vnc server on window 11 with a screen size of 2400x1400

  • Start the VNC client and connect to fastcameraATCA1.dhcp.lbl.gov

  • Run the auto-start script

    ~/CameraControl/python/fccd_auto_start.py Sets up the FCCD. When running this script the Camera Interface Node led panel’s bottom-right light will cycle in order red>yellow>green as it configures the device.

  • Check the fiber optics status

    ~/CameraControl/python/get_FOPS_Status.py This script prints the monitor values of the fiber optics hardware. It should show approx. 4.49 V and 2.71 A.

  • Launch the FCCD gui

    ~/CameraControl/fccd_gui/CINController.py Launches the main

  • Click [Connect]

  • Under [Expose], select Exposure Mode -> Continuous

    When all modules are masked in the fcric, the standard test pattern is sent. The fiber optic test pattern can also be sent; this is toggled with: - setFOtestpatter_on.py - setFOtestpattern_off.py

Starting Tsuru

Tsuru is fully configured to start automatically. The FCCD GUI must be closed for Tsuru to receive data. The FCCD GUI also interrupts the EPICS IOC. After closing the FCCD GUI, the EPICS IOC must be restarted.

Restarting the EPICS IOC

The EPICS IOC is configured to run as a systemd service. To restart it, use:

    sudo systemctl restart epics.service

For more info on systemctl, see Arch’s systemd.

Notes

  • Configure Tsuru networking
    • 2: ens4f0 = 10G -> 10.0.6.42 (Not sure if 5 or 6)
    • 4: enp179sf0 = Base -> 192.168.1.42
