A two-dimensional laser-wire scanner for electron accelerators

An Electro-Optic Deflector for a Fast Laser-Wire Scanner

A large aperture electro-optic deflector has been designed, realized and tested for application on a laser-wire-scanner for particle accelerators. Results on the important parameters such as deflection strength, speed and mode quality preservation are shown and discussed.

Laser-driven plasma-wave electron accelerators

Wavefront-sensor-based electron density measurements for laser-plasma accelerators.

Characterization of the electron density in laser produced plasmas is presented using direct wavefront analysis of a probe laser beam. The performance of a laser-driven plasma-wakefield accelerator depends on the plasma wavelength and hence on the electron density. Density measurements using a conventional folded-wave interferometer and using a commercial wavefront sensor are compared for diffe...

First staging of two laser accelerators.

Staging of two laser-driven, relativistic electron accelerators has been demonstrated for the first time in a proof-of-principle experiment, whereby two distinct and serial laser accelerators acted on an electron beam in a coherently cumulative manner. Output from a CO2 laser was split into two beams to drive two inverse free electron lasers (IFEL) separated by 2.3 m. The first IFEL served to b...

A sector scanner for real time two-dimensional echocardiography.

During the past several years one-dimensional pulse-echo ultrasound techniques have proven extremely useful in cardiac diagnosis. A one-dimensional system, however, only visualizes structures lying along a single straight line. The spatial relationships of the various cardiac structures are therefore not so easily defined as with two-dimensional systems which display the heart by constructing a...
