Experimental investigation of a pulse line ion accelerator in Lanzhou

In order to put the Pulse Line Ion Accelerator (PLIA) concept to its practical application, a small experimental platform was built. It was found that the actual axial electric field is smaller than the theoretical calculation, so the accelerated ions will enter into the deceleration zone before leaving the helix, which will seriously affect the acceleration process. Based on the improved parameters, the He⁺ with 24 keV is accelerated to 55 keV, and the proof-of-principle experiment is completed on this platform. (authors)
