The intense laser-matter interaction allows the charge-separation field to be as high as 100 GV / m, which is three orders of magnitude greater than conventional RF accelerators and accelerates charged particles to GeV energy within a centimeter range, thus replacing the traditional Accelerators have aroused widespread interest in the scientific community. Among many laser ion acceleration mechanisms, ion beam obtained theoretically by Radiation Pressure Acceleration (RPA) has the characteristics of small energy dispersion, large beam density and high energy conversion efficiency. It is the frontier and hot point of current research. Although the RPA theory and one-dimensional simulation results are very attractive, it is still difficult to obtain the expected good results in the experiment at present. However, the most important reason for removing the experimental laser target parameters is the violent development of instability in high-dimensional conditions. The mainstream view is that mainly Rayleigh-Taylor (RT) instability has a negative impact. This instability eventually leads to electron heating and mass loss in the simultaneously accelerated plasma sheet, resulting in a Coulomb explosion of the plasma sheet, accelerated destruction, and ultimately poor ion beam quality. How to curb the occurrence of instability is one of the most challenging issues in RPA research at present. Many methods have been proposed and studied, but the actual results have not been satisfactory. Fig.1 Schematic diagram of dynamic stabilization of light pressure acceleration After years of in-depth research, Qiao Bin task force at Peking University, another way, according to a completely different idea, consider how to dynamically compensate for the acceleration of light pressure instability instability caused by the role of Rather than just suppress the instability of this One idea is that the ionization effect of high-Z coating is proposed for the first time to dynamically replenish electrons during the acceleration of laser light to compensate for the electron loss of the accelerated plasma sheet caused by RT instability so as to achieve dynamic stabilization RPA (Figure 1) . This new approach is very "skinned" and three-dimensional particle simulations show that with the current real laser and target parameters, this scheme enables stable photoionization acceleration and can be used to accelerate high-Z heavy ion sources (Figure 2).

Relevant research results recently published in Physical Review Letters [118, 204802 (2017)]. The PRL reviewer gave a high evaluation of the program and believed that this work made an important contribution to the research field of laser light acceleration and revealed the importance of dynamic ionization in the interaction between intense laser and heavy ions.
