Abstract: | 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. |
