Pulsed Electron-Beam Heating
A pulsed, 20 kv electron beam is focussed upon a vapor-deposited thermocouple, and the resulting temperature vs. time response is studied. The experimental data show much scatter, but are consistent with the theoretical prediction that the characteristic thermal response time T is proportional to d , where d is the beam diameter at the thermocouple. From these data, for the soft-glass substrate...
متن کاملStudies on electron beam induced DNA damage and repair kinetics in lymphocytes by alkaline comet assay
Background: Exposure to ionizing radiation is known to induce oxidative stress followed by damage to critical biomolecules like lipids, proteins and DNA through radiolysis of cellular water. Since radiation has been widely used as an important tool in therapy of cancer, the detailed investigation regarding the DNA damage and repair kinetics would help to predict the radiation sensitivity of cel...
متن کاملThe effect of high-energy electron beam on drawn and undrawn high density polyethylene fibers
HDPE monofilaments were obtained using different extruders and drawn by post-extruder equipments. After solidification, drawn and undrawn monofilaments (draw ratio 7:1) were irradiated with 10 MeV electron beams in air at room temperature at 25, 50, 75, 100 and 125 kGy dose ranges to induce a network structure. HDPE crosslinking was studied on the basis of gel content measurements. The fibers w...
متن کاملA High Current, High Gradient, Laser Excited, Pulsed Electron Gun
This paper describes a pulsed electron gun that can be used as an FEL, as an injector for electron linear accelerators or for rf power generation. It comprises a 1 to 5 MeV, 1 to 2 ns pulsed power supply feeding a single diode, photoexcited acceleration gap. Beam quality of a ~ 1nC charge in ~ 1 GV/m field was studied. Computations of the beam parameters as a function of electrode configuration...
متن کاملPolygonization and plastic bending of whiskers induced by pulsed power electron beam
Dynamics of bending of NaCl whisker is studied with use of high speed camera VFU-1 synchronized with high power electron accelerator GIN-600. The dynamics of bending turns to be non-monotonous and quite complicated. The figures of etching of whisker after bombardment by electron beam are analysed, thin polygonization in samples is found. The time of bending in experiment and time of forming of ...
