Abstract— Diagnostics have been developed for measuring the efficiency of stripping a beam of negative ions in a gas stripping target of a tandem charged particle accelerator. The coefficient of ion-electron emission during the bombardment of copper by protons with an energy of 1 MeV was measured. A bending magnet with a horizontal nozzle was installed, which made it possible to place a Faraday cup and receive a stream of neutrals formed on it as a result of incomplete stripping of negative ions in the stripping target. Diagnostics of the efficiency of the gas stripping target were put into operation on the basis of measuring the current of electrons emitted from the surface of a Faraday cup during its bombardment by a directed stream of neutrals and the proton current by a non-contact current sensor.

真空绝缘的串联式加速器气提靶效率的诊断

摘要—已经开发出用于测量在串联带电粒子加速器的气体汽提靶中汽提一束负离子的效率的诊断工具。测量了在质子轰击铜时，能量为1 MeV的离子电子发射系数。安装了带有水平喷嘴的弯曲磁体，该磁体可以放置法拉第杯，并可以接受由于剥离目标中负离子的不完全剥离而在其上形成的中性流。诊断气体汽提靶效率的方法是根据测量法拉第杯表面受到定向中性流轰击的法拉第杯表面发射的电子电流以及通过非接触电流传感器测量质子电流来进行的。
