Abstract

Three beam lines for secondary charged particles are constructed in the hadron experimental hall of J-PARC. The K1.8 beam line, which incorporates two separators, delivers clean beams of kaons up to 2 GeV/c. The K1.8BR beam line is a branch of K1.8, for low-momentum particles up to 1.2 GeV/c. The K1.1BR beam line is a shorter line designed for low-momentum kaons. Details of these beam line designs, as well as the commissioning results, are described.
