Energetic particle deposition is one kind of thin film synthesis technique based on energetic beam, such as, IBAD, PLD, IBD etc, which is considered to be of good prospect for wide range of applications. However, comprehensive and systematic understanding has been hardly achieved about the growth mechanism of energetic deposition, especially low energetic deposition.

By comparing and analyzing the solar and interplanetary data of two typical fast halo Coronal Mass Ejections, we have found that the event far away from Coronal Holes caused a great Solar Energetic Particle event, but the event very close to CHs did not cause a major SEP event.

The influences of the shock thickness and Alfven waves on the particle acceleration by diffusive shock waves are numerically studied through solving one-dimensional diffusive equation including the second-order Fermi effect. It is shown that the spectral index of the energetic particles strongly depends on the shock thickness. For example, the spectral index increases from 2.1 to 3.7 in the low energy range of 3-10 MeV and from 2.5 to 5.0 in the high energy range of 20-60 MeV as the thickness increases. The spectral index decreases from 4.3 to 3.1 as the particle injection energy increases. The spectral index decreases from 4.0 to 1.8 at the quasi-steady stage with the enhancement of the compression ratio from 2 to 4. The results indicate that under the influence of Alfven waves, the energetic particle spectrum at lower energy becomes flat and the spectral index decreases from 2.5 to 0.6 in the low energy range of 3-10 MeV and from 11.6 to 5.0 in the high energy range of 20-60 MeV. At the same time, the rollover energy reaches 19.6 MeV. The spectral index decreases from 5.8 to 2.9 as the energy density of Alfven waves increase. All these results are basically consistent with the theoretical models, as well as the observations of typical energetic particle events.
