A Separated 1.17-Bev/c K- Meson Beam

PDF Version Also Available for Download.

Description

This report describes the design and testing of a 1.17-Bev/c separated K{sup -} beam designed in the fall of 1958 in connection with a 15-in. hydrogen bubble chamber experiment. At the target the K{sup -}/{pi}{sup -} ratio was 1/140. At the chamber, after two stages of electromagnetic separation and 4.0 K{sup -}-meson decay lengths, the K{sup -}/{pi}{sup -} ratio was 12.5, corresponding to a total pion suppression by a factor of about 10{sup 5}. The K flux at the chamber was 0.87 K{sup -} per 10 protons on the target.
