Mechanisms Engineering Test Loop - Phase 1 Status Report

Argonne National Lab. (ANL), Argonne, IL (United States), D. Kultgen, USDOE Office of Nuclear Energy (NE), C. Grandy et autres

This report documents the current status of the Mechanisms Engineering Test Loop (METL) as of the end of FY2016. Currently, METL is in Phase I of its design and construction. Once operational, the METL facility will test small to intermediate-scale components and …

Development and beam test of a continuous wave radio frequency quadrupole accelerator

Peter N. Ostroumov, B. Mustapha, A. Barcikowski, C. Dickerson et autres

The front end of any modern ion accelerator includes a radio frequency quadrupole (RFQ). While many pulsed ion linacs successfully operate RFQs, several ion accelerators worldwide have significant difficulties operating continuous wave (CW) RFQs to design specifications. In this paper we describe …

Development at ANL of a Copper-brazed Joint for the Coupling of the Niobium Cavity End Wall to the Stainless Steel Helium Vessel in the Fermilab SSR1 Resonator

W. Toter, L. Ristori

In order to reduce the sensitivity of the Fermilab SSR1 resonator to helium pressure variations, it was concluded that the cavity and helium vessel end-walls needed to be structurally coupled by means of a transition ring. With the materials t o be …

A 57-MHz CW RFQ for the AEBL Project

D. Schrage, Peter N. Ostroumov, A. Barcikowski, M. Bracken et autres

High power test of a 57-MHz CW RFQ.

Peter N. Ostroumov, A. Barcikowski, B.E. Clifft, B. Rusthoven et autres

High power heavy-ion drivers require a CW low-frequency RFQ for initial acceleration. The low frequency specifications required for heavy-ion acceleration typically result in large dimensions of the structure. By appropriate choice of the resonant structure for the Rare Isotope Accelerator (RIA) driver …

NIOBIUM TO STAINLESS STEEL BRAZE TRANSITION DEVELOPMENT

J. D. Fuerst, W. Toter, Kenneth W. Shepard

We present results of an R&D program to develop and test a reliable cryogenic leak-tight, copper-brazed transition between niobium and stainless steel for use in superconducting niobium cavities. We have chosen to make the integral helium container that houses a niobium cavity …

Fabrication Techniques for Septum Magnets at the APS

M. Jaski, K. Thompson, Sang On Kim, Horst W. Friedsam et autres

The design, construction, and installation of pulsed septum magnets for particle accelerators presents many challenges for the magnet engineer. Issues associated with magnet core structure design, component alignment, weldment design, and electrical insulation choices are among those requiring careful attention. The designs …
