Revision as of 15:16, 8 November 2021
Compton simulations were done per tagger counter for both the Be and He targets. The initial photon energy corresponds to the central energy of each TAGH(M) counter (excluding counters that tag photons below 6 GeV), and 250k events were generated for each counter (using gen_primex_compton). The Be target simulations were done using run number 61321, whereas the He target simulations were done using run number 61914. All simulations were carried out in hdgeant4.

Note: The Compton simulations were all done per tagger counter, because they are used to calculate the Compton scattering acceptance for each counter. However, this means they are potentially only usable for the 2019 runs, since for the 2021 data set, the tagger counter energies are different. If one tries to reconstruct the hddm files using calibration constants from the 2021 runs, in many of the files DBeamPhotons will be not reconstructed as the beam energy will fall outside of the tagging counter's range. More simulations will be run soon for the 2021 data set, and this page will be updated thereafter.
