In high intensity proton synchrotrons, linear and nonlinear betatron resonances cause beam loss. When the betatron tune spreads over a resonance line, the betatron oscillation amplitude will get larger, causing large beam loss. In the quadrupolar beam transfer function, the coherent space-charge tune shift of quadrupolar beam oscillations is used to determine the incoherent tune shift. China Spallation Neutron Source (CSNS) is a high intensity accelerator based facility consists of linear accelerator and the Rapid Cycle Synchrotron (RCS). A system of quadrupolar pick-up and kicker can be used for evaluating tune shifts and spreads. This paper will present already existing beam diagnostic instrumentation on CSNS/RCS, and discuss feasibility study of measurement of quadrupolar beam oscillations through adding a quadrupolar-type beam pick-up.
