Epics Applications

A collection of applications for Epics using Python

install

On Linux, you will need to make sure that wxPython is installed. For an Anaconda envirornment,

conda -c conda-forge install wxpython

will work. Then,

pip install epicsapps

will install everything else you need.

StripChart

A StripChart Application, showing live time series of Epics PVs

areaDetector Viewer

A viewer for areaDetector Viewers, with good image properties including automatic contrast levels, a user-configurable Zoom-box, and simple configuration file to add which control variables are shown.

Epics Instruments

A GUI application to group any PVs together into named Instruments, and then save and restore positions for these Instruments by name. That is, you can group for 4 motors together, calling them "Slits", and then save and restore positions called "1x1 mm" and "2x2 mm", etc.

Epics PV Logger

Two related appplications to save and view time-series data for selected PVs. Data collection can be run from a command line application, reading a YAML file to configure which PVs are saved. Data is saved into plain text files in a single folder. A GUI application can help create and modify the configuration file, and start collection. The GUI application can also browse and display the data collected into the PVlog folder.

Microscope Viewer

A GUI application for viewing an controlling a sample stage with a microscope camera. This combines aspects of both areaDetector Viewer and Epics Instruments, as positions of the sample stege can be saved and restored by name.

IonChamber calculations

A commandline application to connect to and read Ion Chamber settings (voltages, amplifier gains) and X-ray energy to compute the fluxes absorbed and transmitted by an Ion Chamber.
