Abstract
A new type of beam transport system for secondary light charged particles (“Large Ω” Beam Course) has been constructed and used to transport surface muons from the decay of pions produced in heavy-ion reactions at RIKEN Ring Cyclotron (RRC). In an experiment carried out using a14N beam of 135 MeV/u and a carbon target of 0.9 g/cm2 thickness, the surface muon intensity obtained in 5×5 cm2 sample was around 100 1/s for 500 nA of the primary beam. This number may be increased by two orders if the energy were doubled.
