Strip Charts

General Info

The target variable strip charts are normally shown on adaql3 which is aside of target rack containing the oven controller. There are four strip charts to monitor different target EPICS variables:

• Oven Temperature
• Target Cell Temperature
• 3He Polarization
• Holding Field Currents

Open Strip Charts

Here are the steps to open these strip charts:

1. Log onto hacsbs2 using account hacuser, password is on the wall.
2. enter the directory Hall_A_Tools and execute New_Tools
3. Now you have EOS Menu, from there, go to Strip Chart menu -> Striptool -> File -> Load -> pick config/halla -> pick E06-010 -> Pick all with "Target" and only one of the "Polarization" files.
