Latest Patents
One of his notable patents is the "Charged particle beam detection system." This system features a Faraday cup detector array (FCDA) designed for position-sensitive charged particle beam detection. The FCDA is integrated with an electronic multiplexing unit (MUX) that enables the collection and integration of charge deposited in the array while simultaneously reading it out. The system boasts a duty cycle for collecting ions greater than 98%. The design allows for independent charge collection by numerous small Faraday cups, enhancing the system's efficiency. The device can measure absolute ion currents with a wide dynamic range from 1.7 pA to 1.2 µA, maintaining a crosstalk of less than 750:1.
Another significant patent is for "Preparative separation of mixtures by mass spectrometry." This invention provides methods and instruments for the preparative separation of mixture components using mass spectrometric techniques. It employs nondestructive ionization methods to generate ionized components, which are then spatially separated by mass and trapped. The techniques allow for the generation of large ion currents, facilitating the rapid accumulation of nanomole quantities of mass-separated components in a short time frame.
