Density Enhancement of Muon Beams with Tapered Glass Tubes

Abstract

We have demonstrated that the beam density of 54 MeV/ c muons can be increased almost by a factor of two when a tapered glass tube is inserted coaxially along the muon beam. The observations are compared with a multiple Coulomb scattering calculation, which reproduces the observation reasonably. This technique opens a new and simple way to increase the muon intensity effectively.
