Generalized N-Dimensional Effective Temperature for Cryogenic Systems in Accelerator Physics

open access: yesQuantum Beam Science
Investigations into the properties of generalized effective temperature are conducted across arbitrary dimensions. Maxwell–Boltzmann distribution is displayed for one, two, and three dimensions, with effective temperatures expressed for each dimension ...

IROC phantoms accurately detect MLC delivery errors

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose We evaluated the impact of random and whole‐bank multileaf collimator (MLC) delivery errors on dosimetric delivery accuracy in the Imaging and Radiation Oncology Core (IROC) phantom audits, as well as differences in delivery accuracy between the IROC phantom prescription and typical clinical fraction sizes.

Asynchronous accelerator with RFQ injection for active longitudinal compression of accelerated bunches [PDF]

open access: yesarXiv, 2000
An asynchronous accelerator is described, in which the principle of its operation permits the active longitudinal bunch compression of accelerated proton beams, to overcome the space charge limitation effects of intense bunches. It is shown that accelerated bunches from an RFQ linac can be adapted for Asynchronac injection for a multiple of choices in ...

Effects of cardiac motion on dose distribution during stereotactic arrhythmia radioablation treatment: A simulation and phantom study

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose Cardiac motion may degrade dose distribution during stereotactic arrhythmia radioablation using the CyberKnife system, a robotic radiosurgery system. This study evaluated the dose distribution changes using a self‐made cardiac dynamic platform that mimics cardiac motion. Methods The cardiac dynamic platform was operated with amplitudes

The study of 12C(α,γ) astrophysical reaction using 12C(6Li,d) and 12C(7Li,t) reaction at 20 MeV and in the framework of the potential model

open access: yesEPJ Web of Conferences, 2015
The triton angular distribution in the 12C(7Li,t)16O reaction has been measured at 20 MeV incident energy. Comparison of the data with Finite Range DWBA and CDCC-CRC calculations show that breakup coupling effects are prominent in the transfer to the ...

A multi beam proton accelerator [PDF]

open access: yesarXiv, 2015
The article considers a proton accelerator containing seven independent beams arranged on the accelerator radius. The current in each beam is one hundred milliamps. The initial part of the accelerator consists of shielded spiral waveguides assembled in the common screen.

Nuclear structure of superheavy nuclei - state of the art and perspectives (@ S3)

open access: yesEPJ Web of Conferences, 2018
Decay spectroscopy is a powerful tool to study the low lying nuclear structure of heavy and superheavy nuclei (SHN). Single particle levels and other structure features like K isomerism, being important in the fermium-nobelium region as well as for the ...

Evaluation of the dose reduction effect of crystalline lens exposure in cone‐beam computed tomography with bismuth eye shield for image‐guided radiation therapy: An anthropomorphic phantom study

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract This study aimed to evaluate the dose‐exposure reduction effect of a crystalline lens with a bismuth eye shield using cone‐beam computed tomography (CBCT) for head image‐guided radiation therapy. The ocular surface dose of the head phantom (THRA‐1) is defined as a crystalline lens exposure dose and is measured using a radiophotoluminescence ...
