Scope

  • Below we discuss the procedures necessary to operate the GlueX Start Counter (ST) EPICS GUI in order to operate the Low Voltage (LV) and Bias power supplies.
  • In order to operate the ST from outside the Hall or the Hall D counting house the user will must obtain a Two-Factor Authorization (TFA) device from the Jefferson Lab (JLab) IT help desk.
  • This may be accomplished with two different methods:
  • Obtain a physical authentication token
  • Download the Cryptocard app
  • You must obtain the TFA in person from the IT help desk. The help desk will provide either depending on the users preference.
  • In order to operate the Start Counter EPICS GUI do the following:
  • Begin by ssh'ing into the JLab network in the usual fashion and enter your password.
ssh -X user@login.jlab.org
  • Next ssh into into the hall gateway and enter your TFA password.
ssh -X user@hallgw
  • Now you must ssh into one of the gluon servers (gluon29, gluon51, etc) under the username hdops.
ssh -X hdops@gluon##
  • Password is GlueX_2come
  • Once you are successfully logged into one of the gluon servers you are able to launch the EPICS GUI (CSS-Workspace) and run it in the background.

  • Be sure to select the ST CSS-Workspace when prompted
/gluonfs1/home/hdops/CSS_Workspaces/ST
  • Note that only one ST work space may be operated at any time. Therefore, if the ST work space is currently being operated you will not be able to launch the ST EPICS GUI.
  • Once the CSS-Work space has been launched successfully the ST EPICS GUI will be displayed on the desktop.
  • From here you will be able to control the LV and Bias power distributions to the Start Counter.
  • You will also be able to adjust the ST LV and Bias parameters. However, these values have already been configured so it is imperative that YOU DO NOT MODIFY ANY PARAMETERS without consulting a Start Counter expert first!!!
  1. In order to properly supply LV and Bias to the Start Counter you must follow these steps IN THIS EXACT ORDER:
    1. Turn on the LV power system (pre-amplifier channels & chassis channels). Once the LV monitoring displays are green you may proceed.
    2. Turn on the Bias power system. Once all the channel monitoring buttons are displayed green the Start Counter is fully powered and now fully operational.
  2. To turn off the Start Counter you must follow these steps IN THIS EXACT ORDER:
    1. First, ramp down the bias power system. Once all the channel monitoring buttons are displayed red and no bias is being supplied to ST1 you may proceed.
    2. Second, ramp down the LV power systems. One the LV monitoring buttons are displayed red the Start Counter is powered off.
