对于任何粒子加速器，尤其是对于高能和高强度的机器，非破坏性的束流轮廓监测是非常理想的。基于超音速气体喷射的监测器，检测与要表征的主光束相互作用的气体薄片的电离或荧光，允许进行微创测量。它们还可以用于从keV到TeV束流的广泛能量范围。这篇文章概述了在Cockcroft研究所开发、建造和测试的基于喷射的电离和荧光光束分布监测器。讨论了气膜的产生、真空度的考虑、气体种类的选择和检测方法。
Non-destructive beam profile monitoring is very desirable, essentially for any particle accelerator but particularly for high-energy and high-intensity machines. Supersonic gas jet-based monitors, detecting either the ionization or fluorescence of a gas sheet interacting with the primary beam to be characterized, allow for minimally invasive measurements. They can also be used over a wide energy range, from keV to TeV beams. This contribution gives an overview of the jet-based ionization and fluorescence beam profile monitors which have been developed, built and tested at the Cockcroft Institute. It discusses gas sheet generation, vacuum considerations, choice of gas species and detection methods.
