apace 0.0.5

Another Particle Accelerator Code

apace

apace is yet another particle accelerator code designed for the optimization of beam optics. It is available as Python package and aims to provide a convenient and straightforward API to make use of Python's numerous scientific libraries.

Installing

Install and update using pip:

pip install -U apace

Requirements

• Python 3.6 or higher (CPython or PyPy)
• CFFI 1.0.0 or higher
• NumPy/SciPy
• Matplotlib

Quick Start

Import apace:

import apace as ap

Create a ring consisting out of 8 FODO cells:

d1 = ap.Drift('D1', length=0.55)
b1 = ap.Dipole('B1', length=1.5, angle=0.392701, e1=0.1963505, e2=0.1963505)
q1 = ap.Quadrupole('Q1', length=0.2, k1=1.2)
q2 = ap.Quadrupole('Q2', length=0.4, k1=-1.2)
fodo_cell = ap.Lattice('FODO', [q1, d1, b1, d1, q2, d1, b1, d1, q1])
fodo_ring = ap.Lattice('RING', [fodo_cell] * 8)

Calculate the Twiss parameters:

twiss = ap.Twiss(fodo_ring)

Plot horizontal and vertical beta functions using matplotlib:

import matplotlib.pyplot as plt
plt.plot(twiss.s, twiss.beta_x, twiss.s, twiss.beta_y)
