In plasma based accelerators (LWFA and PWFA), the methods of injecting high qual- ity electron bunches into the accelerating wakeﬁeld is of utmost importance for various applications. Ionization injection has received much recent attention in experiments, in theory, and in simulation. Here we use 3D OSIRIS simulations to investigate generating high quality electron beams generated through ionization injection. This includes the study of two-stage ionization injected LWFA in the self-guided regime. The ﬁrst, i.e., injection, stage is a mixture of 99.5% He and 0.5% N gasses, while the second, i.,e., acceleration stage is entirely composed of He. Laser intensities from 100TW to 1 PW will be modeled. In the 500TW case, energies greater than 3 GeV with 5% energy spread were observed.
