چکیده
Amplified square shaped picosecond pulses was generated for low emittance electron beam generation in a photocathode RF-GUN. Square shaped pulses were generated by using Ti:sapphire amplifier system in inrfared region and then converted to ultraviolet region via third harmonics generation. Generated squares shaped pulses were measeured by crosscorrelation and spectral interferometric technique when the pulse duration was 1 ps, and when the pulse durations of square shaped pulses were 10 ps, these pulses were measured by streak cameras.

Experimental Studies of Photocathode Rf Gun with Laser Pulse Shaping
A technique of laser pulse shaping was developed for low-emittance electron beam generation in a photocathode RF gun. The emittance growth due to space charge and RF effects in the RF gun was experimentally investigated with square and gaussian temporal laser pulse shapes. It is found that the square pulse shaping is a useful tool for both the reduction of nonlinear space charge force and the c...

A femtosecond electron bunch is essential for the observation of ultrafast phenomena. In order to improve the time resolution of pulse radiolysis and ultrafast electron diffraction (UED), that involve the use of an ultrashort electron bunch and ultrashort light, a femtosecond photocathode RF gun was investigated experimentally.

Significant progress has been made in the last few years in ultra-short and high-brightness electron beam production and measurements. For many applications, such as laser and high-frequency RF (W-band) accelerators, and high-gain harmonic generation free electron laser, electron beams with bunch length and transverse emittance smaller than optical wavelength are required. The status of such sm...
