KLF项目中的Berkshire靶概念设计
Conceptual Design of Beryllium Target for the KLF Project
摘要：
K介子产生靶（KPT）是K-Long装置的重要组成部分，该装置将在JLab Hall~D运行，目标是奇异重子和介子谱。在这份说明中，我们提出了一个概念设计的Be-目标组件计划的K-长光束线，这将与GREX光谱仪在其标准配置的拟议实验一起使用。高质量的12-GeV CEBAF电子束能够在GREX靶上产生大约$1\times 10^4 K_L/sec$的K $_L$通量，这超过了先前在SLAC获得的K $_L$通量三个数量级。一个强的K $_L$束将打开一个新的机会窗口，不仅可以在奇怪的强子谱中找到“丢失的共振”，而且可以通过系统地研究不同的衰变通道来确定它们的性质。在K $_L$生产中最重要的辐射损伤背景是中子。KPT的拟议概念设计的蒙特卡罗模拟表明，由此产生的中子和伽马通量导致的KLF实验的即时辐射剂量率低于JLab辐射控制部的辐射剂量率限制在实验大厅和现场边界，并不会实质上影响光谱仪的性能。
英文摘要：
The Kaon Production Target (KPT) is an important component of the proposed K-Long facility which will be operated in JLab Hall~D, targeting strange baryon and meson spectroscopy. In this note we present a conceptual design for the Be-target assembly for the planned K-Long beam line, which will be used along with the GlueX spectrometer in its standard configuration for the proposed experiments. The high quality 12-GeV CEBAF electron beam enables production of a K$_L$ flux at the GlueX target on the order of $1\times 10^4 K_L/sec$, which exceeds the K$_L$ flux previously attained at SLAC by three orders of magnitude. An intense K$_L$ beam would open a new window of opportunity not only to locate "missing resonances" in the strange hadron spectrum, but also to establish their properties by studying different decay channels systematically. The most important and radiation damaging background in K$_L$ production is due to neutrons. The Monte Carlo simulations for the proposed conceptual design of KPT show that the resulting neutron and gamma flux lead to a prompt radiation dose rate for the KLF experiment that is below the JLab Radiation Control Department radiation dose rate limits in the experimental hall and at the site boundary, and will not substantially affect the performance of the spectrometer.
