Laser experiments offer a unique capability to study SNR-relevant collisionless shock in a laboratory. Due to the high velocity of the laser-driven plasma (> 1500 km/s), the ion-ion mean free path is larger than the system. Therefore, the system is weakly magnetized, i.e., MA ~ 150 when applying a 10-T external magnetic field. A novel platform has been developed at OMEGA-EP to study the formation of parallel collisionless shocks relevant to SNRs. The results show the growth of the NRI and ion-Weibel instability, though the NRI appears to dominate at early times. Hybrid-PIC and FLASH simulations will be presented, supporting the experimental observations.
