Imperial launches its first public health online degree
Trading wild specimens and creating new lasers: News from the College
"I am inspired by the drive and ambition of Imperial students"
Laser wakefield accelerators are miniature plasma-based electron acceleration machines, where a highly intense laser pulse is used to rapidly accelerate electrons to high energies.
Electrons oscillating in a laser wakefield emit x-rays, which can be used to image objects at high resolution.
Lasers can be used to accelerate ions from thin foils by the generation of huge electric fields.
A laser can be used to drive a blast wave into a gas jet, shaping the gas to form favourable conditions for ion acceleration.
Preformed plasmas form centimeters to tens of meters are the accelerating medium for present and future, short and long plasma accelerators. At JAI we develop a number of plasma sources to produce these plasmas.
Modelling the interaction of intense lasers with plasmas of various characteristics for particle acceleration and radiation generation.
