Tandem accelerator schematic

Figure 4.13. Schematic diagram of a tandem accelerator source of high energy alpha particles.

Simulation of the neutron-induced damages using triple ion beams is schematically shown in Fig. 7. A proton and a helium ion are provided by the ion implanter and the single-ended accelerator, respectively. Heavy ions, such as iron or silicon, accelerated by the tandem accelerator, are injected into the target simultaneously. For example, the SiC/SiC composite was tested under triple ion beam irradiation consisting of a 380-keV proton, a 1.2-MeV helium ion, and a 7.8-MeV Si " ion. The triple irradiation system is equipped with an energy degrader and a beam scanner for uniform three-dimensional (3-D) irradiation. 

The development of accelerator mass spectrometry goes back to the early days of ion accelerators. Accelerator mass spectrometry (AMS) was developed in 1977 by introducing accelerators (cyclotron and tandem accelerator ) into mass spectrometry. A schematic diagram of a powerful...
