摘要：

Intense laser (> 10(21) W/cm(2)) driven hard x-ray sources offer a new alternative to conventional electron accelerator bremsstrahlung sources. These laser driven sources offer considerable simplicity in design and cost advantage for multiple axis views and have the potential for much higher spatial and temporal resolution than is achievable with accelerator sources. We have begun a series of experiments using the Petawatt laser system at LLNL to determine the potential of these sources for radiography applications. Absolutely calibrated spectra extending to 20 MeV and high resolution radiographs through a rho r greater than or equal to 150 g/cm(2) have been obtained. The physics of these sources and the scaling relationships and laser technology required to provide the dose levels necessary for radiography applications will be discussed. Diagnostics of the laser produced electrons and photons will be addressed. (C) 1999 American Institute of Physics. [S0034-6748(99)66201- 3].
