The subject of this contract is two ion sources
that extend the capabilities of the existing TOF-SIMS5 device.
Traditional ion sources
act like hammers, pulverizing samples in ways that can prevent scientists from seeing a true picture of the material.
Among the topics are theoretical insights into cluster secondary ion mass spectrometry (cluster SIMS), surface analysis of organic materials with polyatomic primary ion sources
, three-dimensional imaging with cluster ion beams, and cluster SIMS for the depth profiling of semiconductors and metals.
Typical applications include injectors used in a gas chromatograph, ion sources
used in mass spectrometry.
US 8,211,411 B2--an oral care composition that contains a fused silica abrasive and an orally-acceptable carrier selected from fluoride ion sources
, antibacterial agents, anticalculus agents, buffers, other abrasive materials, peroxide sources, alkali metal bicarbonate, salts, thickening materials, humectants, water, surfactants, titanium dioxide, flavor system, sweetening agents, cooling agents, xylitol, coloring agents and mixtures thereof.
The neutral beam power will be increased primarily by changing the magnetic configuration of the ion sources
Int'l Workshop on ECR Ion Sources
(16th: 2004: Berkeley, CA) Ed.
The company has accomplished this by using state-of the-art ion sources
in its ion-assisted vapor deposition process.
These mirrors also feature a damage threshold of 1kW/cm2 continuous wave, making them ideal for use with Argon Ion sources
These biases arise from memory effects in ion sources
and affect the reliability and comparability of carbon-13 and oxygen-18 measurements used in studies requiring high interlaboratory reproducibility, including research relevant to climate change.
The combination El/FI/FD ion source
offers both molecular weight information (field ionization and field desorption: Fl and FD) and classical library-searchable (electron ionization: El) mass spectra without having to change ion sources
