  CSNS will build a muon source at the end of the RTBT. In the cur­rent de­sign, the muon source pro­pose two schemes, namely the base­line scheme and the baby scheme. High volt­age elec­tro­sta­tic de­flec­tors (ESD) are used to de­flect the beam in the two schemes. A three-chan­nel ESD with 400 kV HV is em­ployed in the base­line scheme and a 210 kV dual-chan­nel ESD in the sim­pli­fied scheme. Ac­cord­ing to phys­i­cal re­quire­ments, the elec­tric field con­cen­tra­tion fac­tor is in­tro­duced, and the elec­trode of ESD is the­o­ret­i­cally de­signed. 2D and 3D sim­u­la­tions are car­ried out to an­a­lyze the char­ac­ter­is­tics of elec­tric field dis­tri­b­u­tion by OPERA. The geom­e­try of the elec­trodes also met the re­quire­ments of elec­tric field uni­for­mity, high volt­age re­sis­tance and me­chan­i­cal strength at the same time. In the base­line scheme and the baby scheme, the ESD elec­tric field con­cen­tra­tion fac­tors are 1.36 and 1.53, and the max­i­mum elec­tric field is 6.78MV/m and 4.6MV/m, re­spec­tively. The de­sign meets the re­quire­ments and is rea­son­ably fea­si­ble.
