高功率目标防护
Protection Related to High-power Targets
摘要：
目标防护是机器防护的重要组成部分。高强度加速器中的束流功率足够高，单个任性的脉冲可以造成严重的破坏。今天的高功率目标在现有技术的限制下工作，并且是针对非常窄的波束参数范围设计的。如果射束脉冲偏离中心太远，或者射束尺寸不正确，或者射束密度太高，则目标可能被严重损坏。我们将首先简要介绍高功率目标，然后讨论什么可能出错，以及风险是什么。接下来，我们将讨论如何控制与束流相关的风险，然后是几个不同的加速器设施的例子。最后，我们将详细介绍一个橡树岭Sputron中子源目标调整和目标保护的例子。
英文摘要：
Target protection is an important part of machine protection. The beam power in high-intensity accelerators is high enough that a single wayward pulse can cause serious damage. Today's high-power targets operate at the limit of available technology, and are designed for a very narrow range of beam parameters. If the beam pulse is too far off centre, or if the beam size is not correct, or if the beam density is too high, the target can be seriously damaged. We will start with a brief introduction to high-power targets and then move to a discussion of what can go wrong, and what are the risks. Next we will discuss how to control the beam-related risk, followed by examples from a few different accelerator facilities. We will finish with a detailed example of the Oak Ridge Spallation Neutron Source target tune up and target protection.
