摘要
本文简要叙述1GeV/c广量程磁谱仪的结构,包括谱仪磁铁系统和探测器及数据获取系统。推导了在扩展边缘场情况下,非聚焦型磁谱仪的动量公式。用蒙特卡罗方法计算了该谱仪的动量分辨、立体角和动态范围等参数。讨论了多次散射和探测器位置分辨对谱仪动量分辨的影响。
The structure of an 1 GeV/c wide-range magnetic spectrometer is briefly de-
scribed. The spectrometer includes the magnet system and the detector & data acqui-
sition system. The momentum formula at extended edge field case for non-focusing
magnetic spectrometer has been derived. The momentum resolution, solid angle, mo-
mentum acceptance and other parameters for this spectrometer are calculated by Mo-
nte Carlo simulation. The effects of the multiple scattering and position resolution
of the detectors to momentum resolution of this spectrometer are discussed.
