BGO crystal was produced by using Bridgman technique, the maximum dimensions included the β 50 mm x 300 mm length cylinder and 40 mm x 80 mm x 280 mm rectangular shape. And we had abundant experience with special further treatment of BGO crystal, like drilling holes, reflector coating, wrapping and matrix designing.
Scintillation BGO crystal has been proven to be reliable in Oil&Gas wireline logging, and the mineral wireline logging, where the NaI(TI) crystal has been universally used, could be another direction, the lacked of spectrum resolution could be compensated by its high photon fraction for high energy gamma ray naturally occuring from Uranium and Thorium. And included the nuclear medicine field, typically the Computer Tomography(CT), also the high energy physics like the L3 experiment in European Organisation for Nuclear Research(CERN), in which around 12 tons of BGO crystal were used.
