Spectral analysis of radiation emitted transverse to laser propagation in laser-wakefield acceleration experiments shows broadband emission when electrons are accelerated to relativistic energies....
Mangles, SPD, Thomas, AGR, Kaluza, MC, Lundh, O, Lindau, F, Persson, A, ...
Laser wakefield accelerators offer the possibility of compact electron acceleration. However one of the key outstanding issues with the results reported to date is the electron beam stability....
Laser-wakefield acceleration of monoenergetic electron beams in the first plasma-wave period (2006)
Mangles, SPD, Thomas, AGR, Kaluza, MC, Lundh, O, Lindau, F, Persson, A, ...
Beam profile measurements of laser-wakefield accelerated electron bunches reveal that in the monoenergetic regime the electrons are injected and accelerated at the back of the first period of the...
Collimated multi-MeV ion beams from high-intensity laser interactions with underdense plasma (2006)
Willingale, L, Mangles, SPD, Nilson, PM, Clarke, RJ, Dangor, AE, Kaluza, MC, ...
A beam of multi-MeV helium ions has been observed from the interaction of a short-pulse high-intensity laser pulse with underdense helium plasma. The ion beam was found to have a maximum energy for...
Magnetic reconnection and plasma dynamics in two-beam laser-solid interactions (2006)
Nilson, PM, Willingale, L, Kaluza, MC, Kamperidis, C, Minardi, S, Wei, M, ...
We present measurements of a magnetic reconnection in a plasma created by two laser beams (1 ns pulse duration, 1x10(15) W cm(-2)) focused in close proximity on a planar solid target. Simultaneous...
