Title: Alan V Barnes: Innovator in Mass Spectroscopy
Introduction
Alan V Barnes is a prominent inventor based in Livermore, CA (US). He has made significant contributions to the field of mass spectroscopy, holding a total of 2 patents. His work focuses on the development of advanced analytical techniques that enhance surface analysis and spatial resolution.
Latest Patents
One of his latest patents is for a device titled "Highly Charged Ion Secondary Ion Mass Spectroscopy." This innovative secondary ion mass spectrometer utilizes slow, highly charged ions produced in an electron beam ion trap. It allows for ultra-sensitive surface analysis while achieving high spatial resolution. The spectrometer features an ion source that generates a primary ion beam directed at a target surface, along with a mass analyzer and a microchannel plate detector for secondary ions. The high secondary ion yield enables coincidence counting, allowing for the correlation of specific molecular species.
Another notable patent is the "Highly Charged Ion Based Time of Flight Emission Microscope." This instrument improves the surface sensitivity of static Secondary Ion Mass Spectrometry (SIMS) measurements due to the higher ionization probability of highly charged ions. The design includes slow, highly charged ions produced in an electron beam ion trap, which are directed to the sample surface. The resulting sputtered secondary ions and electrons are detected through a specially designed objective lens. This microscope provides high surface sensitivity, high spatial resolution, and valuable chemical structural information.
