Introduction Electron linear accelerator (LINAC) can be used for neutron production in Boron Neutron Capture Therapy (BNCT). BNCT is an external radiotherapeutic method for the treatment of some cancers. In this study, Varian 2300 C/D LINAC was simulated as an electron accelerator-based photoneutron source to provide a suitable neutron flux for BNCT. Materials and Methods Photoneutron sources w...

PLACET[1] is a program used to simulate the dynamics, including wakefields, of a beam in the main accelerating or decelerating part of a linac. It allows for the investigation of singleand multi-bunch effects, the simulation of normal RF cavities with relatively low group velocities, as well as transfer structures specific to CLIC. Recent improvements, including the possibility to simulate bunc...

Abstract Mid-infrared and terahertz free-electron laser (MIR/THz FEL) facility is under the construction at PBP-CMU Electron Linac Laboratory (PCELL) in Chiang Mai University. For producing MIR-FEL, electron beams with an energy of 25 MeV accelerated by a radio-frequency linear accelerator (RF linac) are required. Transporting 25-MeV beam from linac to MIR-FEL station requires small dipole magn...

Dalian Coherent Light Source (DCLS) will use a 300MeV LINAC to produce fully coherent photon pulses in the wavelength range between 150-50nm by high gain harmonic generation free electron laser (FEL) scheme [1]. Beam quality requirements for the linear accelerator (linac) are critical, including not only the beam brightness, but also the stability and the reliability. In this paper, optimizatio...

For superficial lesions, the electrons may be used for radiation therapy. The high energy photons and electrons are produced by a Linear accelerator (Linac). Many of electron fields need the shielding of normal or critical organs. The electron shields are usually lead slabs with few millimeter thicknesses which should be placed near the skin, less than 1 cm away from skin. In the inspection of ...

The Astra simulation code has been successfully used in the design of linac and rf photoinjector systems utilizing beams with azimuthal symmetry. We present recently implemented changes to Astra that allow tracking of beams in beamlines without the assumption of any symmetry. The changes especially include a 3D mesh space charge algorithm and the possibility to import 3D electromagnetic field m...

In this Technical Note, we describe an in-house video goggles feedback system assembled using several commercially available products. This goggle video feed-back system is currently being used at University of Louisville and Mayo Clinic for both CT simulation and linac treatment delivery. The setup details, including specific recommendations, are provided, along with an alternative option for ...

To design of the high intensity ion linac the study of the effect of space charge on the beam quality can be done preliminary by simulation. CIC code was developed to research the dynamics of the bright beam in the periodic accelerating structures. The details are discussed.
