When analyzing the data, all the runs in a particular day were added together for better statistics.  First, the raw data was used to determine where the neutrons cut would need to be placed for each run (or each day of runs if they were able to be combined).  Applying those neutron cuts to each TDC, coincidences were found.  The TDC spectra of the detectors that detected these coincidences were then analyzed to determine the spot on the detectors where each neutron hit.  Knowing the location of detection, the theta and phi angles between coincident neutrons were found.

When analyzing the data, all the runs in a particular day were added together for better statistics. First, the raw data was used to determine where the neutrons cut would need to be placed for each run (or each day of runs if they were able to be combined). Applying those neutron cuts to each TDC, coincidences were found. The TDC spectra of the detectors that detected these coincidences were then analyzed to determine the spot on the detectors where each neutron hit. Knowing the location of detection, the theta and phi angles between coincident neutrons were found.
