This repository contains some basic scripts relevant to the paper: "Single-photon counting pixel detector for soft X-rays" F. Baruffaldi, A, Bergamaschi, et al.

Content: Scripts: file_read.py - function to open an EIGER raw open_one_dataset

    fit_scurve.py
        - example of a function to fit a threshold scan with an s-curve

    open_one_dataset.py
        -  this simple script opens one threshold scan dataset,
        plots one full frame, plots the threshold scan of one pixel,
        performs the fit with the scurve function

    calculate_charge_collection_efficiency.py
        - this script calculates the charge collection efficiency 
        as a function of the photon impinging point in a pixel,
        given the charge-cloud dimensions (sigma of a 2d simmetric gaussian)
        and pixel-pitch
        - the output is saved as .txt file in the folder "charge_collection"

    calculate_lgads_spectrum.py
        - this script calculates the simulated spectrum of a single LGADs pixel,
        given the photon energy, charge collection efficiency (see previous script),
        design parameters of the LGAD sensor, electronic noise of the read-out 

Folders:
    charge_collection
        - the outputs of the script "calculate_charge_collection_efficiency.py" are saved here 

    simulated_absorption
        - .txt files containing simulated photon absorption in silicon,
        produced with Geant4, for different photon energies
