Simulating a Linac¶

In this section, we will be building various beamlines for simulation using one or more beam dynamics codes and running the simulation. Although running a simulation with a single beam dynamics code can be done easily without Python, this is required to run further parameter scan and optimization in LISO.

Building an injector using ASTRA¶

Prerequisite: ASTRA and Configuration

from liso import Linac


# Instantiate a Linac object
linac = Linac()

# Add a beamline which is simulated by ASTRA
linac.add_beamline('astra',
                   name='gun',
                   swd='../astra_files',
                   fin='injector.in',
                   template='injector.in.000',
                   pout='injector.0450.001')

# Define parameters which are defined within a pair of angle bracket in the
# template file.
params = {
    'laser_spot': 0.1,
    'main_sole_b': 0.2,
}

# Run the simulation (test whether everything is set up properly)
linac.run(params)
