Shielding a room using aluminum foil

A local hospital was interested in shielding some sensitive equipment and contemplated installing a shielded room. The room under consideration was the typical laminated wood core panel with galvanized steel on both surfaces, with a RF shielded door, honeycomb air vent panels and filters for ac power, telephone and any other signals, meeting the shielding effectiveness requirements of MIL-STD-2...

Numerical Simulation of Relativistic Electron Beam Generation with a Foil Diode

Atmospheric propagation experiments at the Air Force Weapons Laboratory utilize a 150 KA, 6 MV relativistic electron beam produced by field emission in a foil diode. To characterize the beam for the experiments requires an understanding of beam formation in the diode. To this end CCUBE, a sophisticated two-dimensional, time dependent, particle-in-cell code developed at Los Alamos National Labor...

Optimization of Dual Scattering Foil for 6 to 20 MeV Electron Beam Radiotherapy

From last 50 years, electron beam therapy has an important radiation therapy modality. The electron beam from the LINAC is of size ∼ 2 mm, whereas the size required for actual treatment is usually larger than 2 × 2 cm up to 25 × 25 cm at the isocenter. In the present work, it is proposed to use dual scattering foil system for production of clinical electron beam. The foils for 6 to 20 MeV elect...

Direct Measurement of Medical Linear Accelerator Electron Beam Width at Scattering Foil Position

Purpose: The aim of this study was to develop a method for the direct measurement of electron beam width and distribution at the scattering foil on the carrousel in a medical linear accelerator gantry head, which differs from an existing indirect method for measuring the focal spot size using a camera or metallic slit located outside the gantry head. Methods: The electron beam emitted by the li...

Design of dual scattering foil for 6 to 20 MeV electron beam radiotherapy

The electron beam from the linear accelerator is of size ~ 2 mm, whereas the size of the electron beam profile required for actual treatment is usually larger than 2 2 cm up to 30 30 cm at the iso-center. Therefore, scattering foils were optimized and simulated using FLUKA code. The primar scattering foil as kept niform thickness y w u , whereas the secondary foil was of Gaussian shape with var...
