摘　　要：SECRAL-II is a third generation fully superconducting ECRIS(electron cyclotron resonance ion source)and nearly a duplicated one of SECRAL(superconducting electron cyclotron resonance ion source with advanced design in Lanzhou).They have the same magnet structure locating the axial solenoid coils inside the radial sextupole magnet.Compared with SECRAL,SECRAL-II has a slightly higher radial field and a larger plasma chamber,which makes it suitable for operation at 28 GHz.Meanwhile,the cryogenic system of SECRAL-II was built with integrated LHe recondensation cryogenic system and operated with 5 GM cryocoolers that are capable of providing a dynamic cooling capacity of more than 5 W to the 4.2 K reservoir.The main parameters of SECRAL-II are shown in Table 1.
