Sentence examples for beam radioactivity from inspiring English sources

Managing considerable background events from natural sources and the beam radioactivity is a challenging aspect of this measurement.

The airborne radioactivity induced by particles escaping the beam dump and the activation of the beam dump cooling water circuit were also quantified.

"Our biggest concern is the danger of beam loss, resulting in the release of radioactivity," said Scott M. Cullen, counsel to an East End environmental group, Standing for Truth About Radiation.

As such radioactivity is produced by deuteron beam loss and secondary neutrons with energy up to 50 MeV, the materials selection is important for minimizing the radioactivity after about one day cooling time.

From an analysis of induced radioactivities in candidate materials, the beam loss along the linac needs to be reduced below ∼5 nA/m.

Heat transfer is still a critical point, however, when high beam currents are used to increase the amount of radioactivity per batch within an adequate irradiation period.

A 2760 kPa N2 gas target with 500 ppm O2 (99.9995%% purity gases; MG Industries) was irradiated with a 17 MeV proton beam for 1 2 min, depending on the amount of radioactivity desired.

The radioactivity produced in the accelerator components due to the deuteron beam loss prolongs the cooling time and may pose a potential limit to the proposed availability of 70%.

Detailed Monte Carlo simulations, for various beam energies and several decay times, were performed to predict the residual radioactivity in the main accelerator components and to estimate the residual dose rate inside the tunnel.

It was his doctoral student Marie Curie who named this property "radioactivity", taking the prefix "radio" from the Greek word meaning beam or ray.

By selecting only events during the T2K beam window and with well-reconstructed vertices in the fiducial volume, the large background rate from natural radioactivity is dramatically reduced.
