| contents | The energetic bremsstrahlung photons up to 100 MeV produced in heavy ion collisions can be used as a sensitive probe to the short range correlation in atomic nuclei. The energy of the $γ$-rays can be measured by collecting the Čerenkov light in medium induced by the fast electrons generated in Compton scattering or electromagnetic shower of the incident $γ$ ray. Two types of detectors, based on pure water and lead glass as the sensitive material respectively, are designed for the above purpose. The $γ$ response and optical photon propagation in detectors have been simulated based on the electromagnetic and optical processes in Geant4. The inherent energy resolution of $0.022+0.51/E_γ^{1/2}$ for water and $0.002+0.45/E_γ^{1/2}$ for lead glass are obtained. The geometry size of lead glass and water are optimized at $30\times 30 \times 30$ cm$^3$ and $60\times 60 \times 120$ cm$^3$, respectively, for detecting high energy $γ$-rays at 160 MeV. Hough transform method has been applied to reconstruct the direction of the incident $γ$-rays, giving the ability to distinguish experimentally the high-energy $γ$ rays produced in the reactions on the target from the random background cosmic ray muons. |
