Eight meters downstream from the target E located a beam current monitor MHC5, which endure intensive scattered particles from Target E and cause large temperature variation, further induce operation and calibration problems. To address these issues, a graphite monitor was designed to replace the older aluminum one. Based on years of operation experiences of this graphite cavity, improvement design has been also considered, including beam positon pickups refinement, on-line calibration methods implementation, as well as manipulation maintenance issues. Detailed aspects of the performance of the monitor and its improvement design will be presented in this paper.
