Active Brazing Joins Titanium-Graphite Beam Target for Subatomic Particle Detection Available to Purchase

Active metal brazing played a key role in the development and fabrication of a modified beam target for particle-physics experiments conducted by Fermilab. The new target consists of a titanium tube filled with stacked graphite fins that were bonded in place by means of active metal brazing. This article describes the vacuum process and the methods used to evaluate the brazed titanium-graphite joints.
