质子加速器

Although the Tevatron produces many orders of magnitude more hadrons than do the machines at KEK and SLAC, it is nevertheless much harder to study the decay of B mesons in proton-antiproton collisions.

虽然Tevatron能比KEK和SLAC的加速器产生多许多个数量级的强子，但是在正负质子的碰撞中研究B介子的衰变仍是非常困难的。

Basing on the Monte-Carlo calculations of the detectors'responses to radiation and n/γdiscrimination ability, their radiation response properties are experimentally investigated on pulsedγrays, X rays from Z-pinch processes, n/X mixed radiation fields of the DPF neutron generator, electron beams of BEPC II Testing Beam Facility.
