Description
The Los Alamos Neutron Science Center (LANSCE) uses 1.25 MW 805 MHz klystrons to power the coupled cavity linac (CCL) that accelerates H- beam from 100 to 800 MeV. Solid-state amplifiers can replace klystrons while providing the same energy input to the CCL. The solid-state amplifiers will require cooling to ensure the radio frequency (RF) components don’t overheat.
The existing water system used for the klystrons will be used to cool the solid-state amplifiers. There will be four “Colosseums”, that consist of a low-level RF blade, 40 high power RF blades, a 40-way splitter, and a 40-way combiner, that will replace one klystron. We must ensure there is sufficient water flow and pressure available to cool all these components. Interlocks are added to the system to ensure the protection of the RF components.
