(Color online) Overview of the target area at the RAL petawatt facility showing the shielding setup and layout of the x-ray CCD, CVD diamond, diamond PCD, and scintillator-photomultiplier detectors.
(Color online) Signals from the CVD diamond hard x-ray detector recorded at from the target inside and outside of the target chamber.
(Color online) (a) Setup of the six-channel diamond PCD detector. (b) A diamond is mounted in a modified SMA connector. (c) A lead collimator limits the solid angle to an area close to the target. (d) An additional aluminum collimator is inserted into the lead collimator for EMP shielding.
(Color online) Data from one channel of the diamond PCD array mounted inside the target chamber from two shots on CH∕CD∕CH targets of thickness irradiated with a pulse at best focus with (a) 340 and (b) of laser energy.
(Color online) Trace from one channel of the PCD array mounted on the target chamber wall, showing that the device shorts out at high proton fluxes.
(Color online) Signals from one PCD showing the EMP pickup of an (a) unshielded detector compared to (b) a detector with an additional Al collimator for EMP shielding.
(Color online) Neutrons were seen from CD targets using the scintillator-photomultiplier detector. Results from a non-neutron-producing Au target are shown for comparison.
(Color online) Proposed grounding and shielding for the TIM diagnostic insertion setup on OMEGA EP.
