The absorbed dose to water is the reference physical quantity for the energy absorbed in tissue when exposed to beams of ionizing radiation in radiotherapy. The SI unit of absorbed dose to water is the gray (Gy = 1 J/kg). Ionization chambers are used

Superconducting tunneling junction devices are being developed as energy resolving photon counting imagers. We have fabricated a series of Ta/Al/AlOx/Al/Ta devices with variable Al layer thickness, dAl, and measured their response to a weak visible p

Time-of-flight mass spectrometry-most notably matrix-assisted laser-desorption-ionization time-of-flight (MALDI-TOF) spectrometry-is an important class of techniques for the study of proteins and other biomolecules. Although these techniques provide

A review of cryogenic particle detectors is presented. A major motivation for developing this type of particle detector is their superior sensitivity to weakly ionizing particle interactions. This makes them suitable devices for detecting solar neutr

When irradiating type II superconducting Sn films with alpha particles at temperatures slightly below T c , pulses are observed which can be explained by the particle induced change of the vortex flow resistance. Experimental results are presented an

A cryogenic detector is proposed which is a combination of the thermal calorimeter and the nonthermal superconducting detector: a bolometer crystal covered with a superconducting film. The detector is exposed to microwaves with an energy less than th

To extend the technique of mass spectrometry for analyzing large protein complexes, more sensitive detectors are required. Cryogenic detectors operate by measuring the energy deposition of a single molecule. Their detection sensitivity is independent

Macromolecules with masses up to 50 kDa have been detected with a cryogenic particle detector in a MALDI time‐of‐flight biopolymer mass spectrometer. The cryogenic particle detector was a Sn/Sn‐ox/Sn tunnel junction operated at a temperature of
