摘要：

DD-produced protons are used to measure the imploded fuel-shell areal density rho Delta R. Twelve green beams of the GEKKO XII laser directly imploded a cryogenic foam-shell target containing a liquid or solid D-2 fuel. The proton emission is detected through a dipole magnet on a CR-39 plate, whose energy shift from 3.02 MeV yielded the maximum rho Delta R of 10 mg/cm(2) or the density of 6 g/cm(3), 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.
