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,filename
16-Jan-2024,6.5e-07,Ar,13.56,10,2,2,25,90,Data\SPMeasurements_1.txt
16-Jan-2024,6.5e-07,Ar,13.56,10,2,2,25,45,Data\SPMeasurements_2.txt
16-Jan-2024,6.5e-07,Ar,13.56,10,2,2,25,30,Data\SPMeasurements_3.txt
16-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 on
BPmbar -> Background pressure in mbar
Gas -> Working gas
FrequencyMHz -> generator frequency in MHz
PowerW -> generator power in W
CableLengthm -> Cable length between the generator matchbox and the electrode feedthrough in m
PressurePa -> working pressure in Pa
Distancemm -> Distance between the probe and the electrode in mm
Angle -> Angle of the electrode surface relative to the magnetic field
filename -> 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
