A high-energy carbon-ion radiotherapy facility is under construction at Gunma University Heavy Ion Medical Centre (GHMC). Its design was based on a study of the heavy ion radiotherapy at the National Institute of Radiological Sciences (NIRS) in order to reduce the size and construction cost of the facility. A compact electron cyclotron resonance ion source (ECRIS) for Gunma University, called KeiGM, was installed in 2008. It is almost a copy of the prototype ECRIS Kei2 which was developed by NIRS; meanwhile this prototype produced over 1 e mA of C{sup 4+} using C{sub 2}H{sub 2} gas (660 W and 40 kV). The beam intensity of C{sup 4+} was 600 e {mu}A with CH{sub 4} gas (250 W and 30 kV). The beam intensity satisfies the required value of 300 e {mu}A.
