134 sample multi-cathode source of negative ions by cesium sputtering (134 MC-SNICS)

XCAMS: The compact 14C accelerator mass spectrometer extended for 10Be and 26Al at GNS Science, New Zealand

“…The ion source is a 40-position MC-SNICS [15,16], equipped with a spherical ioniser, an immersion lens between the ioniser and cathode, and a modified Cs delivery system. Hence, this version captures only a subset of the modifications developed and incorporated at KCCAMS and NOSAMS [9,17,18].…”

Computer simulation of MC-SNICS for performance improvements

“…The negative ion source is an essential part in an AMS system, and to date, AMS ion sources are almost exclusively Cs sputter ion sources. The National Electrostatics Corporation (NEC) multicathode source of negative ions by cesium sputtering (MC-SNICS) [2,3] has widely been used for AMS around the world. To achieve higher throughput and better quality of AMS measurements, a collaborative effort is being made by several AMS labs and NEC on ion source performance improvements.…”

Program and status for the planned underground accelerator in the Dresden Felsenkeller

“…2). It consists of a National Electrostatics (NEC) 5 MV pelletron tandem, model 15SDH-2, external 134 MC-SNICS multi-cathode cesium sputter ion source [10], electromagnets for the low and high energy ends of the tandem, and complete beam lines. This system has previously served as an accelerator mass spectrometer for 14 C analyses in an industrial setting [11].…”
