Long‐Term Observations of Galactic Cosmic Ray LET Spectra in Lunar Orbit by LRO/CRaTER

Space Weather, 2020
The Cosmic Ray Telescope for the Effects of Radiation (CRaTER) has been orbiting the Moon since 2009 aboard the Lunar Reconnaissance Orbiter (LRO). From this vantage point, it samples the interplanetary energetic particle population outside the shielding

Lineal Energy of Proton in Silicon by a Microdosimetry Simulation

Applied Sciences, 2021
Single event upset, or Single Event Effect (SEE) is increasingly important as semiconductor devices are entering into nano-meter scale. The Linear Energy Transfer (LET) concept is commonly used to estimate the rate of SEE.

Energy Transfer Rate in Double-Layer Graphene Systems: Linear Regime

, 2012
We investigate theoretically the energy transfer phenomenon in a double-layer graphene (DLG) system in which two layers are coupled due to the Coulomb interlayer interaction without appreciable interlayer tunneling.

Radiation quality assessment in a clinical helium-ion beam using a SOI microdosimeter and a Timepix3 detector

Frontiers in Physics
Accurate characterization of radiation quality is essential for assessing radiobiological effects in radiotherapy, yet remains a major challenge. As modern treatment strategies increasingly consider not only absorbed dose but also linear energy transfer (

Microdosimetric concepts relevant to HZE-particles [PDF]

, 1977
The biological effectiveness of HZE-particles i s determined by the extreme microscopic concentrations of energy transfer in the vicinity of the particle tracks. The concept of linear energy transfer fails to describe this situation adequately.

Radiosensitization Effect of Talazoparib, a Parp Inhibitor, on Glioblastoma Stem Cells Exposed to Low and High Linear Energy Transfer Radiation

Scientific Reports, 2018
Despite continuous improvements in treatment of glioblastoma, tumor recurrence and therapy resistance still occur in a high proportion of patients. One underlying reason for this radioresistance might be the presence of glioblastoma cancer stem cells ...
