Latest Patents

One of his latest patents is for a positron microscopy system that utilizes image enhancement to address challenges associated with low positron source flux. This system can operate in both transmission and reflection modes. In this invention, slow positrons emitted after moderation are focused onto a specimen target. The source beam can be swept over the target to facilitate scanning. Image enhancement is achieved through a channel electron multiplier array (CEMA), which generates a cloud of electrons in response to each incident positron. These electrons are then accelerated toward a long persistence phosphor screen, allowing for effective image acquisition via a low light video system. The data collected is stored in memory and analyzed using an image analysis algorithm to improve signal averaging.

Another significant patent involves a multi-sample scintillation counter that employs position-sensitive detectors. This arrangement counts detectable events, such as scintillation events in a specimen sample, using first and second detector elements positioned on either side of the sample. The first detector provides information about the event's position, while the second generates a timing signal. In certain embodiments, both detectors issue timing signals that are compared for temporal coincidence, triggering circuitry to determine the event's position. This innovative approach allows for the total energy of the event to be calculated from the analog amplitudes of the timing signals.
