beamline

Accelerator online model and lattice visualization package developed by <code>Python</code>.

Developing language: <code>Python 2.7 and 3.x</code>

As of release 2.0.0, Python 3.x is supported, (1.x.y supports Python 2.7).

Documentation: https://archman.github.io/beamline/

Main Features:

• Parsing <code>elegant</code> (electron accelerator tracking code) lattice file (.lte) to be python dict or json string for further operations.
• Modeling accelerator magnetic elements, such as dipole, quadrupole, drift, etc. to be python objects, from EPICS control environment to OOP level.
• Automatic modeling from .lte lattice file definition with postfixed '!epics' anotation to define EPICS control configurations.
• Support unit conversion between EPICS PV raw value and the physical real value of elements.
• Modeling lattice beamline from modeled elements, constructing Lattice instance, dumping .lte file for code tracking.
• Feeding defined elements with new configuration, interfacing with EPICS environment, to form the close-loop online system.
• Visualizing the lattice layout by predefined elements' style.
• Friendly native-look GUI application to facilitate these functionalities.
