Dataset for 2022 July Frankfurt experiment using prototype SHADES array of one EJ-309 liquid scintillator surrounded by six 3He proportional counters.
Neutrons produced from 7Li(p,n)7Be reaction with protons bombarding 3.1um Li deposited on copper. 

Seventeen directories are available, one for each data aquisition run.
Each directory contains:
1. A settings.xml file for the CoMPASS data aquisition software
2. A run.info file containing information saved by CoMPASS about the run, including the start, stop, and real times
3. The RAW data files saved in .root format. Sequential subruns are indicated with a _# ID. The first run has no such ID, i.e DataR_run1878.root

Of the seventeen runs, there are:

. One environmental background run: runBG

. Two gamma-ray source calibration runs: runCs137 and runCo60

. Fourteen beam runs, where the run number is the Van de Graaff energy reading of the proton beam in keV. 

The energy calibration is provided on the website: https://exp-astro.de/vdg_calib/
and repeated here:
  vdg(en) = ((en * 1000) - (0.0233918604095 * en * 1000 + (-21971.1904839))) / 1000.
where vdg is the Van de Graaf energy reading in keV, and en is the actual proton beam energy in keV.

The RAW data files contain the following branches:
. The digitiser "Channel" as a UShort_t  (Channel 0 = EJ-309, channels 1-6 = 3He counters)
. The event "Timestamp" as a ULong64_t
. The CoMPASS "Flags" as a UInt_t
. The waveforms "samples" as a TArrayS* binned to 4ns, as set by the sample rate of 250 MSample/s
