Energetic electrons traveling in a dispersive medium can produce Cerenkov radiation.
Cerenkov photons' prompt emission, combined with their predominantly forward emission …

Thallium bromide (TlBr) is a semiconductor material and, simultaneously, a good Cerenkov
radiator. The performance of a TlBr detector that integrates two different readouts, the charge …

Silicon photodetectors (PDs) operating at near‐IR wavelengths with high speed and high
sensitivity are becoming critical for emerging applications, such as light detection and …

Positron emission tomography (PET) is the most sensitive in vivo molecular imaging
technique available. Small animal PET has been widely used in studying pharmaceutical …

Assessing the position of the Bragg peak (BP) in hadron radiotherapy utilizing prompt-
gamma imaging (PGI) presents many challenges in terms of detector physics. Gamma …

Among the detector materials available at room temperature, thallium bromide (TlBr), which
has a relatively high atomic number and density, is widely used for gamma camera imaging …

This study introduces an X-ray imager that uses TlBr detectors and demonstrates its
potential for X-ray imaging applications. Although TlBr detectors are suitable for X-ray …
