A combined unit,which has the ability to measure the current and emittance of the high intensity direct current (DC) ion beam,is developed at Peking University (PKU).It is a multi-slit single-wire (MSSW)-type beam emittance meter combined with a water-cooled Faraday Cup,named high intensity beam emittance measurement unit-6 (HIBEMU-6).It takes about 15 seconds to complete one measurement of the beam current and its emittance.The emittance of a 50-mA@50-kV DC proton beam is measured.
