A mixed cluster ion beam to enhance the ionization efficiency in molecular secondary ion mass spectrometry.
RATIONALE Chemical modification of a rare gas cluster ion beam (GCIB) to increase the intensity of desorbed molecular ions in secondary ion mass spectrometry experiments relative to the pure Ar cluster. METHODS Doping of the GCIB by mixing small concentration levels (1-3% relative partial pressure) of CH4 into the Ar gas driving the cluster ion source. RESULTS Mass spectra measured on a tre...

Performance of a corona ion source for measurement of sulfuric acid by chemical ionization mass spectrometry
The performance of an ion source based on corona discharge has been studied. This source is used for the detection of gaseous sulfuric acid by chemical ionization mass spectrometry (CIMS) through the reaction of NO−3 ions with H2SO4. The ion source is operated under atmospheric pressure and its design is similar to the one of a radioactive (americium-241) ion source which has been used previous...
متن کاملMeasurement of Ion Beam from Laser Ion Source for Rhic Ebis
Laser ion source (LIS) is a candidate of the primary ion source for the RHIC EBIS. LIS will provide intense charge state 1+ ions to the EBIS for further ionization. We measured plasma properties of a variety of atomic species from C to Au using the second harmonics of Nd:YAG laser (532 nm wave length, up to 0.5 J / 6 ns). Since properties of laser produced plasma is different from different spe...
