The Cryo Control Panel (CCP) is a set of LabVIEW program (VIs) that monitors and controls various devices used in the target system.  CCP is running on the target computer in the control room.

CCP Main Panel

"CCP_Main.vi" is the Main panel of CCP.

It is to start/stop all subsystems under CCP and overview the key readings from them.

CCP Sub Panels

Each subsystem (~controllor) has its own panel (=CCP sub panel) for detailed monitoring and control.

A sub panel can be opened by clicking the "Open" button of corresponding controller on the Main panel.

Spill Counter

The Spill Counter is not a part of CCP but an important program which counts the spill signals from the accelerator and assign spill ID.

It should be launched at the top right corner of the target computer display.

Handling of Problems/Alarms

  • The "Status" of a sub panel is "Black" on the CCP Main Panel, i.e. the sub panel is not running:  
    1. Click the "Start All Subsys" button on the CCP Main Panel.
    2. If the "Status" doesn't become Green, call the target expert.
  • The "Status" of a sub panel is "Red" on the CCP Main Panel, i.e. the sub panel has an error:  
    1. Click the "Open" button on the CCP Main Panel.  A sub panel should pop up.
    2. Click the "Stop" button on the sub panel.
    3. Click the "Start All Subsys" button on the Main (not Sub) Panel.
    4. If the "Status" doesn't become Green, call the target expert.

How to Restart Sub Panel

  1. Click the "Stop" button of the sub panel.
    1. If it doesn't stop, you might have to terminate the LabVIEW process via the Windows Task Manager.
  2. Click "Start All Subsys" () on "CCP_Main.vi".
    1. You should not click the "Run" button of the sub panel, because the sub panel will (sometimes) stop once its window is closed.

How to Stop CCP

  1. Click "Stop All Subsys" () on "CCP_Main.vi".
  2. Click "Stop This Panel" ()on "CCP_Main.vi".
  3. Click "Stop" () on "Spill_Counter_Main.vi" and close its window, if it is running.
  4. Close all LabVIEW windows, whose window titles are "*.vi".
  5. Close the LabVIEW banner window, which pops up once all "*.vi" windows are closed.

If any step gets stuck, you might terminate the LabVIEW process via the Windows Task Manager:

  1. Open the Windows Task Manager (by hitting Ctrl-Alt-Del).
  2. Right-click "LabVIEW 19.0.1f3 Development System".
  3. Select "End task".

How to Stop Target Computer

  1. Select "Restart" (or "Shutdown") from the Start Menu.

How to Start Target Computer

  1. Boot up the Target Computer.
  2. Click the "SX Virtual Link" icon () in the taskbar.  It opens the window of SX Virtual Link and auto-connects USB devices.
  3. Click the desktop icon "Spill_Counter_Main.vi" ().  It starts LabVIEW and opens the window of "Spill_Counter_Main.vi".
  4. Click the "Run" button () of "Spill_Counter_Main.vi".

How to Start CCP

  1. Click the desktop icon "CCP_Main.vi" ().  It opens the window of "CCP_Main.vi".
  2. Click the "Run" button () of "CCP_Main.vi".
  3. Click "Start All Subsys" () on "CCP_Main.vi".
  4. Enable software controls as needed.  All software controls are disabled when the CCP is opened.  Software controls are usually enabled in the following subsystems:
    1. MagRetBypass_Main.vi
    2. Fridge_Valve_Main.vi
    3. GV_Bypass_Main.vi
