| Abstract: | This paper describes the diagnostic techniques and experimental methods used for investigating the properties of implosion compression in direct drive. Several diagnostic techniques with fine time, space and spectrum resolution are employed to obtain the information concerning implosion, such as radiation uniformity on the capsule, compression symmetry, volume compression ratio, implosion time, implosion velocity and average electron temperature of the capsule shell. Some of the typical results measured in the experiments are presented and a simple discussion is also given. |
