We report here on the direct generation of a CN- ion beam for the production of a N ion beam to be used in nuclear astrophysics measurements. The procedure relies on the production of CN- ion beam with a SNICS source starting from several appropriate substrates containing CN- triple bond. Several of the investigated substrates showed a higher beam intensity with respect to the common N beam production from a cathode of BN plus graphite. Best results in terms of analyzed beam intensity were observed with K3Fe(CN)(6) and KSCN cathodes. Use of the latter compound is particularly appealing because of the easy availability of mass-15 enriched molecule.

Abstract
We report here on the direct generation of a CN- ion beam for the production of a N ion beam to be used in nuclear astrophysics measurements. The procedure relies on the production of CN- ion beam with a SNICS source starting from several appropriate substrates containing CN- triple bond. Several of the investigated substrates showed a higher beam intensity with respect to the common N beam production from a cathode of BN plus graphite. Best results in terms of analyzed beam intensity were observed with K3Fe(CN)(6) and KSCN cathodes. Use of the latter compound is particularly appealing because of the easy availability of mass-15 enriched molecule.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
