D052100200004 INC-SOURCE Two reactions were used to produce the 7Be beam both D052100200005 using a 3He gas target. 3He(7Li,7Be)T Q = -0.88 MeV D052100200006 and 3He(6Li,7Be)D Q = +0.11 MeV. There is a factor 2 D052100200007 in the production rate between these two reactions D052100200008 the 3He(6Li,7Be)d being the higher. The proton rich D052100200009 7Be secondary beam has clearly more contaminants D052100200010 compared to the neutron rich 6He and 8Li and this is D052100200011 due to the fact that the proton rich beams normally D052100200012 have lower magnetic rigidity compared to the neutron D052100200013 rich beams and in general lower than the primary.

D052100300004 INC-SOURCE The 6He secondary beam was produced by 9Be(7Li,8Li)8Be D052100300005 reaction with Q=+0.3674 MeV, by impinging about 300 nAeD052100300006 primary beam of 7Li on the 16 mu-m thick 9Be productionD052100300007 target. The primary 7Li beam is produced by the NEC D052100300008 multi-cathode snics ion source with an intensity of D052100300009 typically 100 pnA (particle nano-Amperes).
