SupreKEKB Linac injector generates and accelerates electron beam and positron beam for SuperKEKB High Energy Ring (HER) and Low Energy Ring (LER) injection. At the same time, Linac also undertakes the electron beam injection tasks for Photon Factory (PF) and Photon Factory Advanced Ring (PF-AR). Four rings simultaneous injection has been realized from phase II commissioning. During 4 ring simultaneous injection, non-destructive beam measurements are important for high quality injection, one synchrotron radiation monitor (SRM) is constructed after the last bending magnet of Linac J-arc section. Two dimensional and pulse by pulse beam profiles have been obtained successfully and applied for nondestructive beam adjustment from 2020c operation. In this work, the design and operation results of J-arc SRM are introduced.
