Microinstabilities excited in the foot of a supercritical perpendicular shock wave areinvestigated. A two-dimensional full particle simulation with periodic boundaryconditions in both directions using the physical ion to electron mass ratio is performed as aproxy for the foot region where incoming and specularly reflected ions overlap. Thesimulation shows that six types of different instabilities are excited in a time period shorterthan ion gyroperiod of the reflected ions. The most dominant instability is the modifiedtwo-stream instability, which leads to strong parallel electron heating through aso-called two step instability and to ion phase space holes.
