Linac4 Technical Design Report [PDF]

, 2006
Linac4 is an H- linear accelerator, intended to replace Linac2 as injector to the PS Booster (PSB). By delivering to the PSB a beam at 160 MeV energy, Linac4 will provide the conditions to double the brightness and intensity of the beam from the PSB ...

Comparison of Gamma Sources (Cobalt and Cesium) for Density Measurement of Metals and Alloys via Using Transmission Technique

Journal of Engineering Technology and Applied Sciences, 2021
One of the solutions for density measurement is to make use of gamma-ray transmission technique. We studied by this technique, using by Co-60 and Cs-137. Each source, without materials in geometry, was counted and noted intensities as (I0). All materials were counted and noted intensities as (I). [I/I0] rates were calculated.

The first result in the determination of the percentage concentration of sulfuric acid solution based on the gamma transmission technique with an energy of 662 ke

Science and Technology Development Journal - Natural Sciences, 2021
In this study, we propose an approach using the gamma transmission technique based on the combination of the experimental and simulated data for determining the percentage concentration of the acid solution. The experiment consists of a collimated 137Cs radioactive source emitting a narrow gamma beam of 662 keV and a NaI(Tl) detector.

Examination for Practical Use in Dual Energy Gamma-ray Transmission Techniques. Application to Grading of Gold Alloys.

RADIOISOTOPES, 1995
For practical use of dual energy gamma-ray transmission techniques in various fields, necessary conditions have been examined experimentally.The study revealed the necessary conditions shown in the following : (1) the shape and size of the collimator aperture for a gamma-ray beam must be changed according to those of a sample to be measured, (2) a ...
