Pulse response of the GaAs/GaAsP superlattice photocathode

نویسندگان

چکیده

Pulse responses of different materials commonly used as electron sources in photoinjectors have been determined. Thin film photocathodes, such strained GaAs/GaAsP superlattice and K2CsSb, produce fast responses. The emission intensity at time scales comparable with the acceptance accelerators is found to be reasonably low, which an advantage for operation high beam powers. temporal these cathodes are compared response bulk GaAs.

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 High Polarization and High Quantum Efficiency Photocathode Using a GaAs–AlGaAs Superlattice*

A charge of 2.3 × 1011 electrons in 2.5 ns at a laser wavelength of 757 nm with a corresponding quantum efficiency (QE) of 2.0% measured at 752 nm was extracted from a −120 kV biased, 20 mm diameter, GaAs–AlGaAs superlattice photocathode. The maximum electron polarization measured with material from the same wafer, but in a different system, was 71% at 757 nm for a QE of 1.0% measured at 752 nm...

Thermal emittance and response time of a cesium antimonide photocathode

Measurements of the intrinsic emittance and response time of a Cs3Sb photocathode are presented. The emittance is obtained with a solenoid scan technique using a high voltage dc photoemission gun. Photoemission response time is evaluated using a RF deflecting cavity synchronized to a picosecond laser pulse train. We find that Cs3Sb has both small mean transverse energy, 1606 10 meV at 532 nm la...

Structural Response of BaTiO3/CaTiO3 Superlattice to Applied Electric Fields

The structural response of a ferroelectric BaTiO3/dielectric CaTiO3 superlattice to the bipolar applied electric field was studied using time-resolved x-ray microdiffraction. Structural results were compared to the polarization-electric field hysteresis curve obtained from electrical measurements. The superlattice x-ray reflections were found to have a broad distribution of intensity in recipro...

Nonlinear THz response of a one-dimensional superlattice

The dynamics of an electron in a one-dimensional superlattice is investigated under the action of a THz electric field. The density matrix equations of motion within a single miniband are solved using a relaxationtime approximation for scattering. The electronic response to THz radiation is obtained by calculating the dipole moment, whence we compute the power dissipated, the THz reflection coe...
