Title: Yungman Alan Liu: Innovator in Mass Spectrometry

Introduction

Yungman Alan Liu is a notable inventor based in Sunnyvale, California. He has made significant contributions to the field of mass spectrometry, holding three patents that showcase his innovative spirit and technical expertise.

Latest Patents

Among his latest patents is a mass spectrometer detector and system that utilizes an ion detector for secondary ion mass spectrometry. This detector features an electron emission plate that is coupled to a first electrical potential, allowing it to emit electrons upon the incidence of ions. Additionally, it includes a scintillator that is coupled to a second electrical potential, which is different from the first. The scintillator is designed to emit photons from its backside when electrons strike its front side. A light guide is also incorporated, which confines the flow of photons emitted from the scintillator's backside. Finally, a solid-state photomultiplier is connected to the light guide, outputting an electrical signal corresponding to the incidence of photons. This innovative system includes multiple detectors that are movable and arranged over the focal plane of a mass analyzer.
