%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%Spiral probe measurements The metadata file is: WP1-3_Metadata.txt and the data are available in the folder Data The metadata file is constructed as follows: Date,BPmbar,Gas,FrequencyMHz,PowerW,CableLengthm,PressurePa,Distancemm,Angle,filename16-Jan-2024,6.5e-07,Ar,13.56,10,2,2,25,90,Data\SPMeasurements_1.txt16-Jan-2024,6.5e-07,Ar,13.56,10,2,2,25,45,Data\SPMeasurements_2.txt16-Jan-2024,6.5e-07,Ar,13.56,10,2,2,25,30,Data\SPMeasurements_3.txt16-Jan-2024,6.5e-07,Ar,13.56,10,2,2,25,5,Data\SPMeasurements_4.txt Date -> Date at which time the measurement where carried onBPmbar -> Background pressure in mbarGas -> Working gasFrequencyMHz -> generator frequency in MHzPowerW -> generator power in WCableLengthm -> Cable length between the generator matchbox and the electrode feedthrough in mPressurePa -> working pressure in PaDistancemm -> Distance between the probe and the electrode in mmAngle -> Angle of the electrode surface relative to the magnetic fieldfilename -> data file name Each measurements data file (e.g. Data.7z/SPMeasurements_1.txt) contains measurements of time-varying potential, magnetic field, and electrode potential for each
