Abstract

Historically, the design and operation of secondary beamlines at CERN’s North and East Areas relied on simplified particle distributions and a beamline acceptance determined solely by collimators. The formalism presented here makes as few simplifying assumptions as possible and can be used to match and design secondary beamlines without time-consuming HPC tracking studies. In this study, the formalism is applied to the development of a new neutrino beamline within the Physics Beyond Colliders framework at CERN. The code is expressed generically, providing tools for designing secondary beamlines with small relative losses.
