flyion

The trajectory of a charged particle in a time-varying electric field

Install

python: 3.7+

requires: scipy, numpy, pandas, matplotlib, tqdm, fastadjust.

git clone https://github.com/ad3ller/flyion
cd ./flyion
python setup.py install

Basic use

from scipy.constants import e, m_e
from fastadjust.io import h5read
from flyion import initialize, fly

# A SIMION file with 3 electrodes converted to hdf5
fil = os.path.join(r"./", "fast_adjust.h5")
fa = h5read(fil)

# many particles, 100 MHz oscillating voltages
initial = initialize(100, sigma_x=1e-3)
df = fly(fa, lambda t: [np.sin(t * 1e8), +200, -300], initial, -e, m_e, dt=5e-10, mode="full")
