An experimental program to demonstrate a novel phase-space manipulation in which the horizontal and longitudinal emittances of a particle beam are exchanged has been completed at the Fermilab A0 Photoinjector. A new beam line, consisting of a TM(110) deflecting mode cavity flanked by two horizontally dispersive doglegs has been installed. We report on the first direct observation of transverse and longitudinal emittance exchange.
一个用于展示新型相空间操控的实验项目已经在费米国家实验室 A0 光电子枪完成，该操控中粒子束的水平和纵向发射度可以相互交换。一个由 TM(110) 模式的偏转型腔和两个水平色散的扭摆构成的新型光束线已经安装完成。我们首次报告了横向和纵向发射度的直接交换观测结果。
