Magneto-optical Trapping in a Near Surface Borehole

Trial Data includes photodiode data from a magneto-optical trap designed for a borehole. Photodiode data records the fluorescence of an atom cloud held within the trap as it is loaded at various depths within the borehole and on the surface both before and after lowering into the borehole.

Data is recorded in CSV files chronologically from 0-267 where each CSV contains a loading curve and in some cases an extended period of atom cloud flourescence. Note that a significant amount of background light is also present from the lasers. Background light can be deduced from the region before the loading curve in each recording. The depths and purpose of each file is recorded in the folder structure. The folder name notes the nature of the recording (stability measurement, in borehole measurement, surface measurement) and the next folder level details the position of the borehole MOT at the time of recording of all included files.
