	Funding: National Natural Science Foundation of China An X-Y coplaner High Intensity Beam Emittance Measurement Unit named as HIBEMU-4 has been developed recently to measure the emmitance of 2 MeV/40mA D⁺ beam at the RFQ exit of PeKing University Neutron Imaging FaciliTY (PKUNIFTY). HIBEMU-4 is based on the slit-wire method, and has two groups of slits in the orthogonal directions. Equipped with user-oriented software, it is able to provide results as root-mean-square(rms) emittance, boundary emittance, Twiss-parameters and phase diagram. In this paper we will mainly discuss the strengths and limitations of HIBEMU-4 at the aspects of mechanical designing and data processing method. In addition the testing of HIBEMU-4 on 1MeV O+ beam as well as 2 MeV/40mA D⁺ is closely presented, which shows HIBEMU-4 is competent in high intensity beam (HIB) emmitance measurements.
