Title: Duncan W MacArthur: Innovator in Radiation Detection
Introduction
Duncan W MacArthur is a notable inventor based in Los Alamos, NM (US). He has made significant contributions to the field of radiation detection, holding a total of 9 patents. His work focuses on developing advanced detection systems for beta and alpha radiation, which are crucial for safety and research applications.
Latest Patents
One of his latest patents is a beta particle monitor for surfaces. This device is designed to reliably detect beta radiation emitted from surfaces. It features an electrically conductive signal collector that is adjustably mounted inside an electrically conductive enclosure. This enclosure may define a single large opening for placing against a surface. The adjustable mounting allows for variations based on the distance from the surface or the expected beta energy range. A voltage source is connected to the signal collector through an electrometer, creating an electric field that collects air ions generated by beta radiation. The current produced is indicated on the electrometer or other display means.
Another significant patent is an apparatus for detecting alpha radiation in difficult access areas. This electrostatic alpha radiation detector measures alpha radiation emitted from inside an enclosure. It comprises an electrically conductive expandable electrode that can be inserted into the enclosure. Once inserted, the electrode is insulated from the enclosure, creating a decay cavity where air ions generated by alpha particles are captured. An electric potential applied between the electrode and the enclosure allows for the measurement of electrical current produced by these air ions.
