An electrostatic separator is one of the key elements of a secondary beam line at the Hadron experimental hall of J-PARC. It generates a transverse electric field along the beam axis to separate particles of the same momentum by their mass differences. Two beam lines for charged secondary particles, K1.8 and K1.1BR, are constructed, to provide kaon beams with less contamination of pions. Three experimental areas, K1.8, K1.8BR and K1.1BR are available for nuclear and particle physics experiments. Two 6-m-separators and a 2-m-separator of a Wien filter type are installed for the K1.8 and the K1.1BR beam lines.
