一个新的柜台实验大厅[K.H. Tanaka 等人，IEEE Trans。马格。 28 (1992) 697] 是在 KEK 12-GeV 质子同步加速器 (KEK-PS) 上设计和建造的。从 KEK-PS 提取的质子束通过新准备的主束线 EP1 引入新大厅，并级联击中两个生产目标。上游靶向低动量 (0.4–0.6 GeV c) 分离光束线 K5 提供次级粒子，下游靶连接到中动量 (0.6–2.0 GeV/c) 分离光束线 K6。 EP1、K5 和 K6 的束流光学设计采用了一些新的想法，以便在 KEK-PS 提供的初级质子的有限能量和强度下增加短寿命二次粒子（例如 kaons 和 pion）的数量和纯度。本文描述了这些新想法以及首次调试结果。
A new counter experimental hall [K.H. Tanaka et al., IEEE Trans. Magn. 28 (1992) 697] was designed and constructed at the KEK 12-GeV Proton Synchrotron (KEK-PS). The extracted proton beam from the KEK-PS is introduced to the new hall through the newly-prepared primary beam line, EP1, and hits two production targets in cascade. The upstream target provides secondary particles to the low momentum (0.4–0.6 GeV c ) separated beam line, K5, and the downstream target is connected to the medium momentum (0.6–2.0 GeV/c) separated beam line, K6. Several new ideas were employed in the beam optical designs of EP1, K5 and K6 in order to increase the number and the purity of the short-lived secondary particles, such as kaons and pions, under the limited energy and intensity of the primary protons provided by the KEK-PS. These new ideas are described in this paper as well as the first commissioning results.
