BESS探测器是一种新型的球载光谱仪，它利用了最近为对撞机实验开发的各种技术。主要科学目标包括测量宇宙线反质子谱，寻找宇宙辐射中的反核，精确测量宇宙线原色。一个薄的超导螺线管线圈产生1T的均匀磁场。圆柱形漂移室位于线圈的内部和外部，并执行连续跟踪。1GeV/c时动量分辨率为0.5%。也就是说，最大可检测刚度为200GV。置于螺线管上方和下方的闪烁计数器示波器提供定时和dE/dx测量以及触发生成。定时分辨率为80ps/计数器。这种圆柱形的配置实现了0.35m2sr的大几何接受度，这对于探测罕见的宇宙射线粒子至关重要。为适应高触发率和大数据量的要求，研制了智能触发电路和快速并行数据采集系统。1993年，BESS装置进行了第一次科学飞行，并在能量低于500 MeV的情况下首次检测到质量测量的反质子
The BESS detector is a new type of balloon-borne spectrometer which utilizes various technologies recently developed for collider experiments. The principal scientific objectives include a measurement of cosmic-ray antiproton spectrum, search for anti-nuclei in cosmic radiation, and precise meaurements of cosmic-ray primaries. A thin superconducting solenoidal coil produces a uniform magnetic field of 1T. Cylindrical drift chambers are located inside and outside the coil and perform continuous tracking. The momentum resolution is 0.5% at 1GeV/c. i.e., the maximum detectable rigidity is 200GV. Scintillation counter hodoscopes, placed above and below the solenoid, provide timing and dE/dx measurements and trigger generation. The timing resolution is 80ps/counter. This cylindrical configuration achieves a large geometrical acceptance of 0.35m2sr which is essential to detect rare cosmic-ray particles. In order to cope with high trigger rate and large data size, intelligent trigger circuits and a fast and parallel data acquision system are also developed. In 1993, the first scientific flight of the BESS apparatus was carried out and the first mass-measured antiprotons were detected at energies below 500MeV
