Journal ArticleDOI
Photonuclear physics when a multiterawatt laser pulse interacts with solid targets
Kenneth W. D. Ledingham,I. Spencer,T. McCanny,Ravi P. Singhal,M. I. K. Santala,Edward B. Clark,I. Watts,Farhat Beg,Matthew Zepf,Karl Krushelnick,Michael Tatarakis,A. E. Dangor,Peter Norreys,Ric M. Allott,D. Neely,R. J. Clark,A. Machacek,Justin Wark,Alan J. Cresswell,David C.W. Sanderson,J. Magill +20 more
TL;DR: Laser-induced nuclear fission in 238U has been demonstrated, a process which was theoretically predicted at such laser intensities more than ten years ago.
Journal ArticleDOI
Effect of the plasma density scale length on the direction of fast electrons in relativistic laser-solid interactions
M. I. K. Santala,Matthew Zepf,I. Watts,Farhat Beg,Edward B. Clark,Michael Tatarakis,Karl Krushelnick,A. E. Dangor,T. McCanny,I. Spencer,Ravi P. Singhal,Kenneth W. D. Ledingham,Scott Wilks,A. Machacek,Justin Wark,Ric M. Allott,R. J. Clarke,Peter Norreys +17 more
TL;DR: It is shown that the gamma-ray beam moves from the target normal to the direction of the k(laser) vector as the scale length is increased, similar behavior is found also in 2D particle-in-cell simulations.
Journal ArticleDOI
Observation of a highly directional γ-ray beam from ultrashort, ultraintense laser pulse interactions with solids
Peter Norreys,M. I. K. Santala,E.L. Clark,Matthew Zepf,I. Watts,F. N. Beg,Karl Krushelnick,Michael Tatarakis,A. E. Dangor,X. Fang,P. Graham,T. McCanny,Ravi P. Singhal,K.W.D. Ledingham,Alan Creswell,David C.W. Sanderson,J. Magill,A. Machacek,Justin Wark,Ric M. Allott,B. Kennedy,D. Neely +21 more
TL;DR: In this article, a bright, highly directional source of γ rays was observed directly behind the target, which were produced by bremsstrahlung radiation from energetic electrons generated during the interaction.
Journal ArticleDOI
Generation of terawatt pulses by use of optical parametric chirped pulse amplification
Ian N. Ross,John Collier,Pavel Matousek,Colin N. Danson,David Neely,Ric M. Allott,D.A. Pepler,Cristina Hernandez-Gomez,Karoly Osvay +8 more
TL;DR: Some spectral narrowing during amplification was shown to be compatible with the time-varying profile of the pump beam and consistent with the measured recompressed pulse durations before and after amplification, respectively.
Journal ArticleDOI
Laser generation of proton beams for the production of short-lived positron emitting radioisotopes
I. Spencer,Kenneth W. D. Ledingham,Ravi P. Singhal,T. McCanny,Paul McKenna,E.L. Clark,Karl Krushelnick,Matthew Zepf,Farhat Beg,Michael Tatarakis,A. E. Dangor,Peter Norreys,R.J. Clarke,Ric M. Allott,I. Ross +14 more
TL;DR: In this article, the possibility of using ultra-intenseense lasers to produce commercial amounts of short-lived positron emitting sources for positron emission tomography (PET) is discussed.
