Introduction: Intraoperative electron radiation therapy (IOERT) is one of the cancer treatment techniques that delivers high doses to tumor bed during surgery. IOERT can be performed by either conventional LINACs or dedicated IORT accelerators such as LIAC (Light Intraoperative Accelerator). Two types of applicators can be used with LIAC dedicated accelerator including conventi...

Neutron energy spectra from 6.25 MeV/u C ions incident on a copper target, 10 MeV/u C ions incident carbon, copper, and lead targets, and O ions incident on a copper target have been calculated using the Quantum Molecular Dynamics model (QMD) [1] coupled to the Generalized Evaporation Model (GEM) [2] in the Particle and Heavy Ion Transport Code (PHITS) [3]. In particular, the influence of the “...

The elastic scattering of kaons from different targets 6Li, 12C, and 40Ca at energies 635, 715, 800 MeV have been studied. equivalent local potential form Kisslinger optical with the eikonal approximation using Wallace expansion up to 2nd order used. depends on density target nuclei, amplitude parameters. Satisfactory fits experimental data are obtained.

In this paper we are molding the phase profile of a Gaussian beam in order to achieve a phase singularity called optical vortex. For this purpose, we apply the beam shaping technique for a 635 nm wavelength radiation using a diffractive optical element with high diffractive efficiency. We use reflective spiral phase plates and fork-like computer generated holograms, fabricated with photolithogr...

The CLIC Test Facility (CTF3) at CERN was constructed by the CTF3 collaboration to study the feasibility of the concepts for a compact linear collider. The test beam line (TBL) recently added to the CTF3 machine was designed to study the CLIC decelerator beam dynamics and 12 GHz power production. The beam line consists of a FODO lattice with high precision BPM’s and quadrupoles on movers for pr...

The use of modeling programs such as MCNP to predict the response of HPGe detectors is increasing in importance. Accurate simulation of germanium detectors to incident gamma rays relies on knowledge of the performance of the detector in different detector-source geometries. Two important performance parameters are the resolution and sensitivity. The resolution is the FWHM and FW.1M/FWHM ratio. ...

The Spallation Neutron Source (SNS) project is a collaboration among Argonne, Brookhaven, Jefferson, Lawrence Berkeley, Los Alamos and Oak Ridge National Laboratories. The Linac, which injects beam into an accumulator ring, is comprised of both normal and superconducting rf (SRF) accelerating structures. Two room-temperature rf structures, a 402.5-MHz drift-tube linac (DTL) and an 805-MHz coupl...

Background: Two protocols of AAPM TG-51 and IAEA TRS-398 were compared followed by a measurement and Monte Carlo simulation of beam quality correction factor, KQ, AAPM TG-51 and IAEA TRS-398 protocols were compared for the absorbed dose to water for DW, and KQ parameters. Materials and Methods: Dose measurements by either protocols were performed with cylindrical and plane parallel ch...

The variation in mass attenuation coefficient μ for total and partial photon interaction processes for three different oxide glasses (65CaO-35Al2O3(OG1) , 20Na2O-80SiO2(OG2), and 20Na2O-5Al2O3-75SiO2 (OG3)), in the incident energy range from 10 keV to 100 GeV has been studied using software package XCOM and the effect of chemical composition on the values of μ is also interpreted graphically. M...

The chopping line is a critical part of the ESS linac in term of technical realisation of the choppers and preservation of the beam qualities. A new optimised design of the ESS RFQs and chopping lines is reported. The beam dynamics has been optimised with H beam currents up to 100-mA to have safety margin with respect to the ESS goals. The first RFQ transmits almost 99.7% of the beam up to 2 Me...
