摘要:

DD‐produced protons are used to measure the imploded fuel‐shell areal density &rgr;&Dgr;Rof a cryogenic foam target. 12 green beams of the GEKKO XII laser directly imploded a cryogenic foamshell target containing a liquid or solid D2fuel. The proton emission is detected through a dipole magnet on a CR‐39 plate, whose energy shift from 3.02 MeV yielded the maximum &rgr;&Dgr;Rof 12 mg/cm2or the density of 8 g/cm3, in agreement with that from the secondary neutron method within a factor of 2. The proton energy spread is sensitive to the laser energy imbalance. ©1996 American Institute of Physics.
