Series of experiments to assess the role of pressure, mass of particles, and grain size distribution in the generation of charges and discharges during shock-tube experiments. Experiments have been achieved between 2017 and 2018 in the facilities of Department of Earth and Environmental Sciences - LMU München. This dataset contains: - an excel spreadsheet summarizing the 63 experiments in the database with their main characteristics - a pdf file for each experiment, with the waveforms of the main instruments used in the experiment (Pressure sensors and Faraday cage) as well as ellaborated data (total amount of charges and discharges, discharge size distribution. Description of the raw file for each experiment (in CSV format). After the header, the columns display respectively: (1) the time [s] (2) the static pressure within the autoclave [MPa] (3) the voltage across the Faraday cage [V] on a low-sensitivity channel of the datalogger (4) the voltage across the Faraday cage [V] on a high-sensitivity channel of the datalogger that might saturate in some cases (5) the voltage across the lower antenna [V] as described in Cimarelli et al., 2014 (for some experiments only, otherwise the signal remains close to 0) (6) the voltage across the upper antenna [V] as described in Cimarelli et al., 2014 (for some experiments only, otherwise the signal remains close to 0) (7) the dynamic pressure at the exit of the nozzle [MPa] (8) the trigger signal generated by the datalogger [V]
