Description
The Los Alamos Neutron Science Center (LANSCE) accelerator complex delivers both protons and negative hydrogen ions and provides various beam patterns simultaneously to multiple users. The LANSCE linac front end is still based on Cockcroft-Walton voltage generators. An upgrade of the front end to a modern, RFQ-based version – a part of the LANSCE Modernization Project (LAMP) – is now in the conceptual design stage. The LAMP will need fast beam choppers both in the low-energy transport (LEBT), before RFQ, and in the medium-energy transport (MEBT), after RFQ. We use CST modeling to develop fast, 1-ns class, current structures for traveling-wave LAMP beam choppers. The structures are based on meander-folded striplines on high-dielectric-constant substrate (alumina). Such structures are expected to be reliable while providing the required short rise / fall times of the deflecting electric field.
