Silicon PhotoMultipliers (SiPM) provide an efficient photon read-out to particle detectors thank to their high photon detection efficiency, their immunity to magnetic fields and their high granularity. Recently SiPMs are being studied for cryogenic application within dark matter or neutrinos detector. This talk will describe the behavior of newest FBK cryogenic SiPMs and the associated...
The Enriched Xenon Observatory (EXO) is aiming to search for 0$\nu\beta\beta$ decays of $^{136}Xe$ by using liquid xenon TPC detector. nEXO is the second phase of EXO with 5 tons of enriched liquid xenon TPC with ultra-low background. In order to meet the requirements of 1% energy resolution (at Q of 136Xe, 2.458 MeV) and low background, ~4 $m^2$ of SiPM arrays will be used to collect 175 nm...
CATIROC is an ASIC designed to read large photomultiplier areas for neutrinos experiments. This “System-on-Chip” is a very innovative concept as it sends out only relevant data by network to the central data storage, minimizing the links and the cost. The ASIC integrates 16 independent channels, with a self-triggering capability down to 1/3 photoelectron (50 fC). It then provides time...
The Baby MIND neutrino particle detector was installed at J-PARC in Tokai Japan in February 2018 and commissioned with first neutrino beam a few weeks later. It is instrumented with 3'996 Hamamatsu MPPCs type S12571-025C. A full readout electronics chain was developed to extract energy deposition and timing information of tracks left by charged particles from neutrino interactions in the Baby...
IceCube-Gen2 is an extension of IceCube Neutrino Observatory at the South Pole to significantly enhance the detection sensitivity to high-energy as well as low energy neutrinos. It occupies $\sim$8 km$^3$ of Antarctic ice and an array of $\sim$10,000 optical modules to capture Cherenkov photons efficiently from the secondary charged particles produced in the neutrino interactions.
The...
Sampling calorimeter is indispensable for physics measurement at collider experiment with particle flow algorithm.
Particle flow algorithm optimized calorimeter is important not only energy information but also position information.
Position information can be improved by creating a very finely granulated detection layer.
However, energy resolution is degraded by uncertainty of deposit...
After the Fukushima nuclear disaster in 2011, large amounts of radioisotopes (mainly $^{137}\mathrm{Cs}$ and $^{134}\mathrm{Cs}$) were released into the environment. Various monitoring activities have revealed radiation on the ground both in local and wide areas; however, aerial dose variation in the vertical direction is poorly known.
This paper presents the first results of airborne...
X-ray computed tomography (CT) is widely used in diagnostic imaging of the interior of the human body; however, the radiation dose of conventional CT typically amounts to 10 mSv. Under such environments, X-ray photons are severely piled-up; therefore, the CT images are monochromatic and various artifacts are present due to beam hardening effects. In contrast, photon counting CT (PC-CT) offers...
Radionuclide therapy (RNT) is an internal radiation therapy that can selectively damage cancer cells. Very recently, the use of alpha-emitting radionuclides was initiated in RNT owing to its dose concentration and short range. In particular, 223-Ra is widely used for bone metastasis cancer. Despite its potential for clinical applications, it is difficult to see whether the drug has been...
