PR20076 X-band Klystron Modulator for the CLARA Facility at Daresbury Laboratory

The final date and time for the submission of bids is the 17th November 2020 at 14:00.

DO NOT apply directly to the buyer.

All tender information MUST be submitted through the Delta eSourcing Portal.

Brief Description of Requirement;

A next-generation light source test facility is to be constructed at the Daresbury Laboratory which will be known as CLARA (Compact Linear Accelerator for Research and Applications), shown in Figure 1. The aim of the CLARA project is to develop a normal conducting test accelerator capable of generating longitudinally and transversely bright electron bunches and to use these bunches in the experimental production of stable, synchronised, ultra-short photon pulses of coherent light from a single pass FEL (Free Electron Laser) with techniques directly applicable to the future generation of light source facilities.

STFC requires 1 klystron modulator to deliver RF power to 1 normal conducting X-band 4th Harmonic cavity (4HC). This klystron must be able to deliver a MINIMUM of 8 MW of RF peak power for 3.0 µs at a repetition rate of 100 Hz.

However a preferred capability of ≥10 MW of RF peak power, with RF pulse widths of up to 3 µs while operating at a repetition rate of up to 100 Hz.

Assuming a klystron efficiency of 40%, the modulator must have a peak power capability of 25 MW. However, it should be noted that these conditions may not all be required at the same time. This specification concerns the design, manufacture, testing, delivery, to Daresbury Laboratory and

documentation of 1 klystron modulator.
