CONSTRUCTION OF A 6×6BGO ARRAY AND ITS MEASUREMENT OF LOW ENERGY PHOTONS

  • A 6×6BGO array as a prototype of precise fully active electromagnetic calorimeter has been constructed.It consists of 36 Chinese-made BGO crystals,each being 20mm by 20mm in cross section and 200mm in depth,equipped with photomultiplier readout.To obtain linearity over a wide dynamic range,both the anode signal and a dynode signal were digitized.The array has been tested with monochromatic photons produced via (p,γ) reactions at the IHEP Van de Graaff accelerator in the energy range up to 21MeV.The response for photons has shown to the linear in this energy range.The FWHM energy resolution obtained follows a E-1/2 dependence and is superior to that of BGO arrays reported in the literature.

Abstract: A 6×6BGO array as a prototype of precise fully active electromagnetic calorimeter has been constructed.It consists of 36 Chinese-made BGO crystals,each being 20mm by 20mm in cross section and 200mm in depth,equipped with photomultiplier readout.To obtain linearity over a wide dynamic range,both the anode signal and a dynode signal were digitized.The array has been tested with monochromatic photons produced via (p,γ) reactions at the IHEP Van de Graaff accelerator in the energy range up to 21MeV.The response for photons has shown to the linear in this energy range.The FWHM energy resolution obtained follows a E-1/2 dependence and is superior to that of BGO arrays reported in the literature.
