Pol He-3 Target Screen Setup

Target Training Slides / Polarimetry How-to

Setup target ladder, stripcharts on HCDESK4

To setup non-LabVIEW screens (stripcharts, target ladder, etc)

  • Go to HCDESK4 (dual monitor linux host to the right of the TO station) and open a terminal on an empty workspace
  • Run go_target
  • Arrange the screens as shown in the snapshot

Suggested Screen Layout

Setup target laser controls on POLTARCC

Connect to the Laser computer (polhe1)

  • Go to POLTARCC (single monitor linux host to the right in the corner of the TO station)
    • Open a terminal on an empty workspace
    • Run go_lasers'
NOTE: This opens a VNC client connecting to the polhe1 Windows computer in the Laser room. 
It will go full screen when it starts.  Hit the F8 key to exit the VNC screen if necessary.

Run the Laser Control and EPICS binder software

Polhe3-lasers-step1.jpg
  • Double-click on the Raytum D-Light Laser Controller, Multiple Station icon in the top-middle of the screen.


Polhe3-lasers-step2.jpg
  • On the Sidebar that appears Double-click on the D-Light Laser Controller, Multiple Station.vi line (highlighted here)


Polhe3-lasers-step3.jpg
  • Click on the white arrow near the top of the window that pops up to run the

program. The system will search for the lasers -- be patient, it can take 30-60 seconds until the desired lasers show 'OK'. Click Accept and the main laser panel will appear with all accessible lasers.

Polhe3-lasers-step4.jpg
  • On the same Sidebar, expand EPICS.lvlib and double-click on Adapter.vi.
    • Click on the white 'run' arrow at the top of the window. This binds the LabVIEW variables to an EPICS IOC for monitoring and logging.


Polhe3-lasers-step5.jpg
  • Minimize (do not close) all windows except for the D-Light Laser Controller window.
    • Your screen should look similar to the snapshot.


LabVIEW software notes

Need to add what folder these can be found in.

EPR software

  • EPR-RM sweep: EPR_FM_PIBOX_0_A1n_D2n.vi
  • EPR-AFP: EPR_AFP_Modified_v3_A1n_D2n.vi

EPICS bindings

  • Laser bindings (polhe1)
  • Polarimetry bindings (polhe4)
