Optical Matching of Slowly Extracted Beam with Transport System at HIMAC

Matching of twiss parameters between the ring and the transport line plays an important role in controlling the beam size. At HIMAC, thus, matching of twiss parameters was realized by using the simulation result. As a result, it was verified that the calculation result was in good agreement with the measurement of the beam size. The distribution of the beam profile in the transport line was also in good agreement with the particle tracking result. This paper describes the controllability of the slowly extracted beam and related development at HIMAC.
