Abstract：
One should pay attention to quite a lot of factors when the emittance of high-current ion beam is measured. The background subtraction and threshold setting, the measuring method of pulsed beam emittance, as well as the error sources in the emittance measurements and its elimination or correction are discussed based on the experience during the R&D of three emittance measurement units for high-current ion beams at Peking University.
