The use of CsK 2 Sb photocathodes in an RF linear accelerator is investigated. Several fabrication techniques for this type of cathodes are reviewed. Measurements are performed on the drop in quantum efficiency due to the use of the cathode in the li

In a master oscillator power amplifier system a powerful train of pulses can be generated. A simple method is described to measure the duration of these pulses. The measurements have been performed both at the fundamental frequency (1053 nm) and at t

We have performed an optimization study on a train of laser pulses in a Nd:YLF master-oscillator power amplifier chain. Instead of using a flat train of input pulses and proper timing of the input pulses with respect to the pump pulse to keep the out

Design considerations concerning a high power XeCl excimer laser are described. The subsystems to be investigated are the gas flow circulating system with a homogeneous velocity profile and thin boundary layers near the electrodes, a pulse power circ

By modification of the conformal transformation used by Chang in determining uniform field electrode profiles, a large improvement can be achieved in the uniformity of the electric field strength distribution over the surface of the electrodes. When

Experiments have been performed on a corona preionization type 10 cm aperture TEA CO2 laser. For a CO2:N2:He=1: 1: 7: mixture an output energy of 34 joule per liter and for a 1 : 1 : 10 mixture 40 joule per liter could be obtained. The overall effici

Simple analytic expressions are derived to design uniform-field electrodes that are superior in compactness and field uniformity to those described in literature. When such electrodes are used in a TEA laser system, smaller electrodes can be used for
