Dear reader, we thank you for your interest in our dataset. In this document, we describe what you will
find in it.

In case you need help with using the dataset, or if you are interested in mutual impedance experiments,
do not hesitate to contact our team in Orléans ([e-mail], [e-mail])

Topic:
This dataset contains the outputs of numerical simulations performed to assess
the impact of plasma inhomogeneities on the diagnostic performance
of mutual impedance experiments.

Numerical model:
The outputs are obtained from a numerical model based on the solution of the 1D-1V Vlasov-Poisson
system of equations. The scheme used to solve the model is the one developed
by Mangeney et al. (2002),  A Numerical Scheme for the Integration of the Vlasov-Maxwell System of Equations. Journal of Computational Physics, (doi: https://doi.org/10.1006/jcph.2002.7071).
The 1D-1V Vlasov-Poisson version of this model is described in Henri, et al. (2010), Vlasov-Poisson
simulations of electrostatic parametric instability for localized Langmuir wave packets in the solar wind,
Journal of Geophysical Research (Space Physics), 115, 6106 (2010)

What is inside the dataset:

The dataset is composed of 7 different mutual impedance measurements, each corresponding to one
directory (see below). The measurements (i.e. directory) correspond to small-scale plasma inhomogeneities at different
positions with respect to the mutual impedance antennas, or to a large-scale plasma inhomogeneity.

Each directory contains a number of folders. Each folder corresponds to the emission of a signal at
different frequency.
-----------------------------------------------------------------------------------------------------
List of directories:

(Note : each directory corresponds to one mutual impedance measurement)

L        :    These outputs correspond to one mutual impedance measurement in
                small antenna emission amplitude, which corresponds to a linear
                plasma response to the emission.

s_xx     :    Each of these outputs corresponds to one mutual impedance measurement in correspondance of
        a small-scale plasma inhomogeneity at xx Debye lengths of distance from the emitting antenna

-----------------------------------------------------------------------------------------------------
List of folders inside the directories:

Folders begin with the name "000" and have increasing index. Inside the same directory, each folder
represents a different simulation used to build the same mutual impedance measurement.

------------------------------------------------------------------------------------------------------
List of files inside the folders:

density_e.npz        :    electron density inside the box, in function of time (tempo)

density_p.npz        :    ion density inside the box, in function of time (tempo)

E.npz            :    electric field in the box, in function of time (tempo)

qrho.npz        :    electric potential in the box, in function of time (tempo)

qrho_imposed.npz    :    electric charge imposed at the emitting antennas, in function of time (tempo)

tempo.npz        :    time-vector for density, electric field, electric potential and charge vectors

TEST_Luca.dat        :    parameters describing the characteristics of the simulated plasma box

[
Note : the previous files can be opened as follows

import numpy as np

vector_file_name = np.load('file_name.npz') # Use these for the .npz files
characteristics_of_the_box = np.genfromtxt('TEST_Luca.dat',skip_header=1)

]

-------------------------------------------------------------------------------------------------------
Characteristics of the simulated plasma box (TEST_Luca.dat)

nx        :    amount of spatial grid points

xl        :    physical size of the spatial box, expressed in Debye length

tt_w        :    time resolution for ion and electron density, electric field, electric potential and charge

rap_m          :    ion-to-electron mass ratio

R_p        :    ion-to-electron temperature ratio

dt        :    time step used to evolve in time the numerical simulation

emission    :    emission frequency

power        :    amplitude of the electric charge imposed at the emitting antennas

(Note : all parameters not listed here but present inside the TEST_Luca.dat file correspond to additional
    functionalities of the model. For the use of this dataset, they can be discarded.)
