LAPECR1(Lanzhou All Permanent magnet ECR ion source No.1)is an all permanent magnet ECR ion source designed to be operated at 1 4.5 GHz to produce intense low and medium charge state ion beams such as He~+,He~(2+),B~+,C~+,C~(2+),O~+,O~(2+),N~+,N~(2+),Ar~+ and also C(4+),O~(6+),Ar~(8+)etc.The typical parameters of the sou rce are given in Table 1.The compact structure of the source makes LAPECR1 a
LAPECR1 (Lanzhou All Permanent magnet ECR ion source No.1) is an all permanent magnet ECR ion source designed to be operated at 1 4.5 GHz to produce intense low and medium charge state ion beams such as He ~ +, He ~ (2+ ), C ~ +, C ~ (2 +), O ~ +, O ~ (2 +), N ~ +, N ~ O ~ (6 +), Ar ~ (8+) etc. The typical parameters of the sou rce are given in Table 1. The compact structure of the source makes LAPECR1 a
