Development and Characterization of Tissue Equivalent Proportional Counter for Radiation Monitoring in International Space Station [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2013
Tissue equivalent proportional counter (TEPC) can measure the Linear Energy Transfer (LET) spectrum and calculate the equivalent dose for the complicated radiation field in space.

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

open access: yesSpace 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

Linear Operator Inequality and Null Controllability with Vanishing Energy for Unbounded Control Systems [PDF]

open access: yes, 2013
We consider a linear boundary or point control system on a Hilbert space $H$ which is null controllable at some time $T_0 >0$. To every initial state $ y_0 \in H$ we associate the minimal ``energy'' needed to transfer $ y_0 $ to $ 0 $ in a time $ T \ge ...

Radially restricted linear energy transfer for high-energy protons: A new analytical approach [PDF]

open access: yes, 1994
Radially restricted linear energy transfer (LET) is a basic physical parameter relevant to radiation biology and radiation protection. In this report a convenient method is presented for the analytical computation of this quantity without the need for ...

Microdosimetric concepts relevant to HZE-particles [PDF]

open access: yes, 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.

Granular Crystals: Controlling Mechanical Energy with Nonlinearity and Discreteness [PDF]

open access: yes, 2011
The presence of structural discreteness and periodicity can affect the propagation of phonons, sound, and other mechanical waves. A fundamental property of many of the periodic structures and materials designed for this purpose is the presence of ...

Current status of high linear energy transfer irradiation [PDF]

open access: yesCancer, 1984
Based on laboratory investigations, high linear energy transfer (LET) particle irradiation is capable of more efficient cell kill than that associated with conventional or low LET irradiation. The advantages of high LET irradiation include: (1) a greater ability to damage hypoxic cells; (2) a lesser ability for repair of sublethal and potentially ...
