Controlling the spectrum of x-rays generated in a laser-plasma accelerator by tailoring the laser wavefront
By tailoring the wavefront of the laser pulse used in a laser-wakefield accelerator, we show that the properties of the x-rays produced due to the electron beam's betatron oscillations in the plasma c...

Ultrafast imaging of photoelectron packets generated from graphite surface
We present an electron projection imaging method to study the ultrafast evolution of photoelectron density distribution and transient fields near the surface. The dynamical profile of the photoelectro...

Bistability of twisted-bend and twisted configuration is found. It is based on the elastic and topological inequivalency of director orientation. Multiple states of minimum local energy exist, with appropriate boundary conditions. The effects of elastic constants, d/P ratio and pretilt angle are also investigated. Fast electrical switching time <500  µs and high average contrast of 45:1 are obtained experimentally. ©2009 American Institute of Physics
