前端目前正在建设中，包括H(-) Penning离子源（65 keV, 60 mA），低能束输运（LEBT）和射频四极（3 MeV输出能量），具有适合高功率质子应用的中等能量束输运。诊断可以分为破坏性技术，如光束剖面监测仪、胡椒罐、狭缝发射扫描仪（最好在调试期间使用）或非破坏性、永久安装的设备，如基于光电分离的技术。另一种确定光束分布的方法是带电荷耦合器件相机的闪烁体。已经进行了第一次控制光束注入LEBT的实验。讨论了粒子能量和空间电荷补偿等束流参数对二维分布和剖面的影响。
A front end is currently under construction consisting of a H(-) Penning ion source (65 keV, 60 mA), low energy beam transport (LEBT), and radio frequency quadrupole (3 MeV output energy) with a medium energy beam transport suitable for high power proton applications. Diagnostics can be divided either in destructive techniques such as beam profile monitor, pepperpot, slit-slit emittance scanner (preferably used during commissioning) or nondestructive, permanently installed devices such as photodetachment-based techniques. Another way to determine beam distributions is a scintillator with charge-coupled device camera. First experiments have been performed to control the beam injection into the LEBT. The influence of beam parameters such as particle energy and space-charge compensation on the two-dimensional distribution and profiles will be presented.
