Abstract
A manifold-coupled linac structure with excellent rf, mechanical, cooling, and vacuum properties is described. The structure is a ''high-US '' structure, suitable for acceleration particles with US =v/c between 0.5 and 1. It consists of a sequence of shaped, single-cell accelerating cavities, each of which is US lambda/2 long and independently slot-coupled to a coaxial manifold which surrounds the lot. The accelerating cavities operate in the lowest cavity mode (TM010), which implies a maximum separation from other cavity modes such as the deflecting modes. The shunt impedance of this structure is essentially that of the shaped, US lambda/2, accelerating cell, degraded by 10-15% for the dissipations in the slots and the manifold. The core of the structure is furnace-brazed copper assembly, which is supported and cooled from the ends (the slots need not be continuous). The outer shell of the structure is a copper-plated steel cylinder. A 20-cell aluminum frequency and field model of this structure is in fabrication. Results of cavity measurements are presented.
