pulse_generator

(Any typo is on purpose.)

Pulses generated by Silicon Photo-multipliers (SiPMs) are characterized by a sharp rise-time followed by an exponential-like decay. This behaviour is due to the sudden surge of electric current generated by the photo-diode by a photon which is then suppressed by a quenching resistor.

This is a small library to simulate a SiPM pulse, with an ideal rise time (1-sample long) and an ideal tail (exponential decay). It is superposed on a baseline of random numbers, to simulate electronic noise.

Usage

Generating a pulse can be as simple as:

pulse_generator = sipm().create_waveforms()

or, if you want to generate 10 waveforms with amplitude between 20 and 30,

pulse_generator = sipm(number_of_waveforms=10, amplitude=[20, 30]).create_waveforms()

Parameters

This is a list of parameters you can give sipm:

• number_of_waveforms: integer with the number of waveforms to be generated.
• amplitude: float or list (with minimum and maximum value of range) with the amplitude of the pulses.
• decay_constant: float telling how wide the pulses are.
• pulse_position: int with where the pulse is generated within the waveform.
• jitter_width: int width around pulse_position.
• baseline_offset: float electronic-noise centre line.
• noise_amplitude: float electronic-noise maximum value around baseline offset.
