We have demonstrated the proposal of determining the hohlraum radiation temperature TR and M-band fraction fm by using a shock wave technique [1,2].The experiments have been conducted on the SGⅡI-prototype laser facility,and two materials Al and Ti are used as shock wave witness plates.This is the first experiment for determining the hohlraum radiation temperature and M-band fraction by using shock wave technique.The partial shock velocities in Al and Ti measured in the experiments are listed in Table 1.
