Electron beam calibration constants

open access: yesJapanese Journal of Radiological Technology, 1978
Electron treatment beam calibration constants are tabulated in a convenient form for mean incident electron energies, Eo, of 6 to 21 MeV; and practical reanges, Rp, of 2.75 to 10.53 cm of water. Values of mean electron energy at depth Ed, chamber radius correction factors (Kp), and CE factors may be readily obtained from this chart.

In-Situ Real-Time Focus Detection during Laser Processing Using Double-Hole Masks and Advanced Image Sensor Software

open access: yesSensors, 2017
In modern high-intensity ultrafast laser processing, detecting the focal position of the working laser beam, at which the intensity is the highest and the beam diameter is the lowest, and immediately locating the target sample at that point are ...

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.

Generation of Multi-Color Attosecond X-Ray Radiation Through Modulation Compression

open access: yes, 2011
In this paper, we propose a scheme to generate tunable multi-color attosecond coherent X-ray radiation for future light source applications. This scheme uses an energy chirped electron beam, a laser modulators, a laser chirper and two bunch compressors ...

Runaway electron beam control [PDF]

open access: yesPlasma Physics and Controlled Fusion, 2018
Post-disruption runaway electron (RE) beams in tokamaks with large current can cause deep melting of the vessel and are one of the major concerns for ITER operations. Consequently, a considerable effort is provided by the scientific community in order to test RE mitigation strategies.
