Photomultiplier tubes (PMTs) and silicon photomultipliers (SiPMs) have played essential
roles in various applications, such as fundamental particle physics experiments, nuclear …

It is widely believed that light is not emitted in water during irradiation of radiation at energies
lower than the Cherenkov light threshold. Contrary to this consensus, we discovered that …

Purpose: The authors previously reported successful luminescence imaging of water during
proton irradiation and its application to range estimation. However, since the feasibility of …

Objective. FLASH radiation therapy with ultrahigh dose rates (UHDR) has the potential to
reduce damage to normal tissue while maintaining anti-tumor efficacy. However, rapid and …

Luminescence imaging of water using X-ray photon irradiation at energy lower than
maximum energy of~ 200 keV is thought to be impossible because the secondary electrons …

The luminescence imaging of water using the alpha particle irradiation of several MeV
energy range is thought to be impossible because this alpha particle energy is far below the …

Although the luminescence images of water during proton-beam irradiation using a cooled
charge-coupled device camera showed almost the same ranges of proton beams as those …

There is an urgent need to develop an automated malaria diagnostic system that can easily
and rapidly detect malaria parasites and determine the proportion of malaria-infected …

Although luminescence of water during irradiations of proton and carbon-ion lower energy
than the Cerenkov-light threshold were found recently, the sources of the luminescence …

Cerenkov luminescence (CL) is blue glow light produced by charged subatomic particles
travelling faster than the phase velocity of light in a dielectric medium such as water or …
