We present the general challenges of plasma diagnostics for laser-produced plasmas and give a few more detailed examples: spherically bent crystals for X-ray imaging, velocity interferometers (VISAR) for shock studies, and proton radiography.

This paper presents the results of experiments conducted within the Work Package 10 (fusion experimental programme) of the HiPER project. The aim of these experiments was to study the physics relevant for advanced ignition schemes for inertial confinement fusion, i.e. the fast ignition and the shock ignition. Such schemes allow to achieve a higher fusion gain compared to the indirect drive approach adopted in the National Ignition Facility in United States, which is important for the future inertial fusion energy reactors and for realising the inertial fusion with smaller facilities.

Point projection proton backlighting was recently used to image a cylindrical imploding target at Rutherford Appleton Laboratory (UK). Due to the relatively low energy and to the very large mass densities reached during implosion, protons traveling through the target undergo a very large number of collisions which reduced the resolution. Here, we present a simple analytical model to study the proton radiography (PR) performance as a function of the main experimental parameters. This approach leads to define two different criteria for PR resolution describing different experimental conditions.
