The injection and extraction energy are 3.7 keV/u and1.025 MeV/u, respectively. Fig. 1 shows the front end section of the SSC-Linac. The high charges state continuswave (CW) 4-rod RFQ has been designed and fabricated for some years. From the end of 2013, the commissioningof the RFQ was performed and the beam test was carried out in April 2014. In this paper the experiment resultwill be presented.展开更多
