该协议提出了一个详细的程序连续，微米级的低温圆柱形和平面液体射流的操作。当按此处所述操作时，射流表现出高度的层状性和厘米级的稳定性。在瑞利状态下，低温液体射流的成功操作需要对低温下的流体动力学和热力学有基本的了解。理论计算和典型的经验值作为指导设计一个可比的系统。本报告确定了低温源组装过程中清洁度的重要性以及液化后低温源温度的稳定性。该系统可用于高重复率激光驱动质子加速，在质子治疗中具有预期的应用。其他应用包括实验室天体物理学，材料科学和下一代粒子加速器。
This protocol presents a detailed procedure for the operation of continuous, micron-sized cryogenic cylindrical and planar liquid jets. When operated as described here, the jet exhibits high laminarity and stability for centimeters. Successful operation of a cryogenic liquid jet in the Rayleigh regime requires a basic understanding of fluid dynamics and thermodynamics at cryogenic temperatures. Theoretical calculations and typical empirical values are provided as a guide to design a comparable system. This report identifies the importance of both cleanliness during cryogenic source assembly and stability of the cryogenic source temperature once liquefied. The system can be used for high repetition rate laser-driven proton acceleration, with an envisioned application in proton therapy. Other applications include laboratory astrophysics, materials science, and next-generation particle accelerators.
