The BGOOD experiment at the ELSA facility in Bonn has been commissioned within the framework of an international collaboration. The experiment pursues a systematic investigation of non-strange and strange meson photoproduction, in particular t-channel processes at low momentum transfer. The setup uniquely combines a central almost \(4\pi \) acceptance BGO crystal calorimeter with a large aperture forward magnetic spectrometer providing excellent detection of both neutral and charged particles, complementary to other setups such as Crystal Barrel, Crystal Ball, LEPS and CLAS.

ELSA的BGOOD实验装置

波恩ELSA工厂的BGOOD实验是在国际合作框架内进行的。该实验对非奇怪和奇怪的介子光产生，特别是低动量传递下的t沟道过程，进行了系统的研究。该设置独特地结合了几乎接受（4 \ pi \）的中央BGO晶体量热仪和大孔径前向磁谱仪，可很好地检测中性和带电粒子，并与其他设置（例如Crystal Barrel，Crystal Ball，LEPS和CLAS）互补。
