We describe our progress on the development of extended interaction klystron amplifiers operating at 670 GHz, meeting demanding requirements for output power, gain, bandwidth, and efficiency.

We describe a model for analytic analysis of transients in multicavity klystron output power and phase. Cavities are mod-eled as resonant circuits, while bunching of the beam is modeled using linear space-charge wave theory. Our analysis has been implemented in a computer program which we use in designing multicavity klystrons with stable output power and phase. We present as examples transient...

Major changes to the Next Linear Collider (NLC) design were facilitated by the experimental testing of the 75 MW X-band klystron at a 3.0 μsec pulse width 1 and new component development allowing the delay line distribution system (DLDS) to operate with eight bins instead of four. This change has a direct effect on the design of the klystron modulator. The general approaches, which are being st...

PPM focusing is quite an attractive scheme, since it eliminates the focusing solenoid (and its power supply) from the klystron. However, one technical difficulty lies in how to integrate the magnetic-circuit, which is relatively complicated, into the vacuum tube. We have solved this problem by introducing a new fabrication technique of metal-to-metal diffusion-bonding by hot-isostatic-pressing ...

Many high-gain free electron lasers worldwide are planning to incorporate seeding setups into their day-to-day operation. These techniques provide both longitudinal and transverse coherence extended control of the output laser radiation spectral properties. However, wavelength repetition rate strongly depend on properties seed system. With peak power required for successful seeded operation, it...

This paper continues our description of a new compact CW linac program started by Schonberg Research Corporation (SRC) under terms of a development contract. This work is now continued by High Energy Systems (HES) Division of AS&E. HES has been formed based on the acquisition of SRC by AS&E. Since we published the design and the first experimental data on the 1 MeV CW linac [1], a complete test...

A switching mode power supply (SMPS) is a hopeful candidate for the 1MW CW klystron power supply of KOMAC (KOrea Multi-purpose Accelerator Complex). The merits of the SMPS are low stored energy, small size, high rating efficiency and possible cost saving whereas the demerits are EMI problem and system complexities. The proposed power is 2MW and it is considered that the modules, each of which h...

Superconducting cavities exhibit a high susceptibility to mechanical perturbations due to the narrow bandwidth of the cavities. Significant phase and amplitude errors can be induced by the frequency variations driven by microphonics and Lorentz force detuning especially in the case of pulsed operation where mechanical resonances of the cavity can be excited. While the relativistic electron and ...
