pyrex.custom.arianna.antenna.LPDA

class pyrex.custom.arianna.antenna.LPDA(name, position, threshold, trigger_window=5e-09, z_axis=(0, 0, 1), x_axis=(1, 0, 0), amplification=1, amplifier_clipping=1, noisy=True, unique_noise_waveforms=10)

ARIANNA LPDA antenna system.

Applies as the front end a filter representing the ARIANNA amplifier and signal clipping.

Parameters

namestr

Name of the antenna.

positionarray_like

Vector position of the antenna.

thresholdfloat

Voltage sigma threshold for the trigger condition.

trigger_windowfloat

Time window (ns) for the trigger condition.

z_axisarray_like, optional

Vector direction of the z-axis of the antenna. The z-axis runs along the central “spine” of the antenna, with the positive direction pointing towards the longer “tines”.

x_axisarray_like, optional

Vector direction of the x-axis of the antenna. The x-axis runs parallel to the “tines” of the antenna.

amplificationfloat, optional

Amplification to be applied to the signal pre-clipping.

amplifier_clippingfloat, optional

Voltage (V) above which the amplified signal is clipped (in positive and negative values).

noisyboolean, optional

Whether or not the antenna should add noise to incoming signals.

unique_noise_waveformsint, optional

The number of expected noise waveforms needed for each received signal to have its own noise.
