We develop 3D integrated Photon-to-Digital Converters (PDC) for photon counting applications needing sub-nanosecond timing resolution. These applications range from LIDAR and quantum communication to radiation instrumentation and medical imaging.
In previous years we reported on the architecture of the PDCs, on their fabrication process, and on two electronic readouts: one optimized for low...
We are developing an integrated mobile X-ray system using carbon nanotube (CNT) technology to overcome the limitations of traditional 2D mobile chest radiography. By incorporating a CNT source array with electronics into a commercial cart, we aim to enable tomosynthesis (limited-angle tomography), providing quasi-3D imaging to improve visualization and diagnostic accuracy. This system is...
The advent and subsequent explosion of portable consumer electronics in the last twenty-five years has led to the development of mass produced, small form factor, high sensitivity, low noise and fast readout rate CMOS imaging sensors (CIS). These now ubiquitous CISs have found multiple scientific applications in nuclear physics and more recently have been adopted for x-ray fluorescence...
Transmit Array Spatial Encoding (TRASE) is an MRI encoding technique utilizing a transmit (Tx) array of radiofrequency (RF) phase gradient coils to achieve spatial encoding, rather than conventional switching gradients of the main magnetic field (B0). TRASE is particularly well suited to low-field, low-cost, and portable MRI systems utilizing lightweight permanent magnets, such as a Halbach...
The Water Monitoring System (WMS) developed at TRIUMF is a novel approach to in-situ water-quality monitoring. Initially, it was developed to track the quality of water samples from water Cherenkov neutrino detectors; the system uses several LEDs along with toggleable filters, a UV sterilizer, and a water deionizer to identify the presence and type of contaminants in a water sample. It has...
