Escherichia coli Cells Exposed to Lethal Doses of Electron Beam Irradiation Retain Their Ability to Propagate Bacteriophages and Are Metabolically Active

open access: yesFrontiers in Microbiology, 2018
Reports in the literature suggest that bacteria exposed to lethal doses of ionizing radiation, i.e., electron beams, are unable to replicate yet they remain metabolically active.

Electron Beam Testing

open access: yes, 1989
Publisher Summary The term “Electron Beam Testing” means the testing of electrical properties of a circuit or an electron device by using the electron beam. The commercial electron beam tester uses the probing action of an electron beam, and it can resolve 0.1 μ m spatially and subnanosecond in time. Its voltage sensitivity reaches 10 mV.

A 3D Miniaturized Glass Magnetic-Active Centrifugal Micropump Fabricated by SLE Process and Laser Welding

open access: yesMicromachines, 2022
A miniaturized pump to manipulate liquid flow in microchannels is the key component of microfluidic devices. Many researchers have demonstrated active microfluidic pumps, but most of them still required additional large peripherals to operate their ...

Transmission electron microscopy with in situ ion irradiation [PDF]

open access: yes, 2015
The macroscopic properties of materials exposed to irradiation are determined by radiation damage effects which occur on the nanoscale. These phenomena are complex dynamic processes in which many competing mechanisms contribute to the evolution of the ...

Operation of a free-electron laser from the extreme ultraviolet to the water window [PDF]

open access: yes, 2007
We report results on the performance of a free-electron laser operating at a wavelength of 13.7 nm where unprecedented peak and average powers for a coherent extreme-ultraviolet radiation source have been measured.

Pepper-pot emittance measurement of laser-plasma wakefield accelerated electrons [PDF]

open access: yes, 2009
The transverse emittance is an important parameter governing the brightness of an electron beam. Here we present the first pepper-pot measurement of the transverse emittance for a mono-energetic electron beam from a laser-plasma wakefield accelerator ...

Collimation with Hollow Electron Beams

open access: yesPhysical Review Letters, 2011
A novel concept of controlled halo removal for intense high-energy beams in storage rings and colliders is presented. It is based on the interaction of the circulating beam with a 5-keV, magnetically confined, pulsed hollow electron beam in a 2-m-long section of the ring.

Method for the use of polymer beads as dosimeters for low-energy electron irradiation

open access: yesFrontiers in Physics
In this study, a novel bead-based dosimetry system was developed. This approach uses suspended polymethyl methacrylate beads, which experience a dose-dependent change in fluorescence intensities.
