چکیده

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 which was employed, if d = 1|JI, T less than 1 \Jsec is predicted. Accepted for the Air Force Franklin C. Hudson Chief, Lincoln Laboratory Office

Studies 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...

The effect of surface roughness on 1050 aluminum alloy weld profile welded by pulsed Nd:YAG laser

Surface roughness in the welding processes is one of the important parameters in the laser welded metal connections which affects laser beam absorption directly. When the laser beam is irradiated to the surface of the base metal, the surface roughness plays an important role in the amount of beam absorption and the amount of melting achieved and directly affects the penetration depth. The main ...

Beam Induced Heating of the Sps Fast Pulsed Magnets

Fast pulsed magnets with ferrite yokes are used in CERN’s SPS accelerator for beam injection, extraction and excitation for tune measurements. The impedance of the ferrite structures can provoke significant beam induced heating, especially for beams with high peak currents as for LHC operation, even beyond the Curie temperature. The expected heating in the different kicker systems for various o...
