Description
At the Montreal Tandem accelerator, an experiment is being setup to measure internal pair creation in 8Be, using a Daphne experiment MWPC and the scintillator bars surrounding it, covering nearly 4-pi. The preamps and data acquisition hardware have been designed and tested. The target, mounted on an Al foil and water-cooled is in a section of the beamline made of C fiber. The experiment will focus on the measurement of the X17 in IPC of the 18.15 MeV state of 8-Be. Assuming the ATOMKI evaluation of the electron-pair production rate from X17, Geant4 simulation predicts observation of a clear signal after about 2 weeks of data taking with 2 uA proton beam. The IPC measurement could eventually be extended to other nuclei: 10B, 12C and 4He.
