The deposit contains data obtained during experiments at the HIGS facility at Triangle Universities Nuclear Laboratory (TUNL), Duke University, in collaboration with the University of Connecticut (Uconn). The experimental work was funded by the U.S. Department of Energy. The data for these experiments were obtained from 2009 to 2011 and exact details of when each data file was generated can be found in the attached experiment runbooks. Data and analysis codes needed to analyse the data are contained within the archive.

M. Gai (Uconn) and M.W. Ahmed (TUNL), each served as the spokesperson of the UConn-TUNL collaboration that collected and released the data. The released data were subsequently analysed at Sheffield Hallam University by R. Smith with the help of S.R. Stern and D.K. Schweitzer at UConn.
