Abstract

This dataset contains the raw experimental data employed in:

Célian Boyé, Jaume Navarro-Cavallé, Mario Merino, "Magnetic arch plasma expansion in a cluster of two ECR plasma sources", Journal of Electric Propulsion.

Which is currently submitted.

 

Dataset description

The experimental data is gathered by means of a Retarding Potential Analyzer (RPA) and a Faraday Cup (FC). The probes have been set on a polar probing arm system to scan the central horizontal plane of the setup, aligned with the axis of symmetry of the assembly and pointing toward the origin at the exit plane of the source(s).

The RPA data is provided separately for every spatial position inspected for each configuration (S0, S1, D0, DA, DB). It is collected by means of an Impedance-Semion Retarded Potential Analyser, with a mean resolving voltage of 1V. The FC data is provided for the DA configuration to support the RPA measurements. 

Please refer to the corresponding article for further details regarding the data collection.

 

Data files

The data files are in standard comma separated values .csv format. Many programming languages provide functionalities to load such fields.





RPA data



The RPA data is separated through the different configurations:







S0: single ECR source without applied magnetic field.

S1: single ECR source with applied magnetic field.

D0: cluster of ECR sources without applied magnetic field.

DA: cluster of ECR sources with opposed polarity.

DB: cluster of ECR sources with same polarity.




The angle steps vary through the different configurations. Each file contains 8 headlines. 







The first column contains the voltage applied to the sweeping grid (V).

The second to sixth columns contain the current collected by the collector (A).

The eventh to eleventh columns contain the derivative of the collected current by the voltage (A/V).








FC data



The FC data has been probed for the DA configuration. The file contains 2 headlines.







The first column contains the angle at which the current has been collected (deg).

The second column contains the distance from the origin at the exit plane of the cluster (mm).

The third column contains the collected current (A).
