Measurement of the decay of laser-driven linear plasma wakefields
J. Jonnerby, A. von Boetticher, J. Holloway +8
We present the first measurements of the temporal decay rate of one-dimensional, linear Langmuir waves excited by an ultra-short laser pulse. Langmuir waves with relative amplitude…
Automated control and optimisation of laser driven ion acceleration
B. Loughran, M. J. V. Streeter, H. Ahmed +32
The interaction of relativistically intense lasers with opaque targets represents a highly non-linear, multi-dimensional parameter space. This limits the utility of sequential 1D s…
Characterisation of Laser Wakefield Acceleration Efficiency with Octave Spanning Near-IR Spectrum Measurements
M. J. V. Streeter, Y. Ma, B. Kettle +25
We report on experimental measurements of energy transfer efficiencies in a GeV-class laser wakefield accelerator. Both the transfer of energy from the laser to the plasma wakefiel…
Single-shot multi-keV X-ray absorption spectroscopy using an ultrashort laser wakefield accelerator source
B. Kettle, E. Gerstmayr, M. J. V. Streeter +19
Single-shot absorption measurements have been performed using the multi-keV X-rays generated by a laser wakefield accelerator. A 200 TW laser was used to drive a laser wakefield ac…
Temporal Feedback Control of High-Intensity Laser Pulses to Optimize Ultrafast Heating of Atomic Clusters
M. J. V. Streeter, S. J. D. Dann, J. D. E. Scott +27
We describe how active feedback routines can be applied at limited repetition rate (5 Hz) to optimize high-power TW) laser interactions with clustered gases. Optimization of…
Anomalous Self-Generated Electrostatic Fields in Nanosecond Laser-Plasma Interaction
L. Lancia, M. Grech, S. Weber +15
Electrostatic (E) fields associated with the interaction of a well-controlled, high-power, nanosecond laser pulse with an underdense plasma are diagnosed by proton radiography. Usi…
