Raw Laboratory Measurements of Ionization Coefficients for Meteoric Fe and Si under Earth's Atmospheric Conditions

Raw laboratory data from ionization coefficient (β) measurements for meteoric Fe and Si. Data were recorded at University of Colorado, Boulder. Files are as recorded by the acquisition system: no reduction, calibration, or fitting has been applied. Each event is recorded as 18 separate single-column text files: 16 charge collectors labeled A through P, plus two additional channels — QD3 and the final detector. Filenames follow the pattern YYYY_MM_DD_HH_MM_SS_1_9_G_10_CH.txt, where the leading timestamp identifies the event, G distinguishes the two acquisition groups, and CH is the channel letter. Files with G=1 and CH = A–P are the 16 charge collectors, in order along the beamline. G=2, CH=A is the final detector and G=2, CH=B is QD3.
