 There is growing interest in physics community in building high energy, high luminosity polarized electron-ion collider in order to study the fundamental structure of nucleons and nuclei and details of QCD theory governing the interaction in nuclear matter. eRHIC will take advantage of existing RHIC ion collider at BNL with addition...

Optimization of electron-beam transport in FEL devices is very important for efficient operation. A new simulation code for electron-beam transport in FELs was developed recently at Tel-Aviv University (TAU) in order to optimize the electron-beam transport. Equations of motion of an electron in the presence of magnetic and electric fields are solved numerically for various magnetic elements. Th...

Significant progress has been made in the last few years in ultra-short and high-brightness electron beam production and measurements. For many applications, such as laser and high-frequency RF (W-band) accelerators, and high-gain harmonic generation free electron laser, electron beams with bunch length and transverse emittance smaller than optical wavelength are required. The status of such sm...

BACKGROUND AND PURPOSE To investigate combining unmodulated electron beams with intensity-modulated radiation therapy to improve dose distributions for superficial head and neck cancers, and to compare mixed beam plans with helical tomotherapy. MATERIALS AND METHODS Mixed beam and helical tomotherapy dose plans were developed for two patients with parotid gland tumors and two patients with na...

The effect of annealing temperature and time on the formation of threading dislocations was investigated for high energy boron implants into silicon. 1 MeV B was implanted at a dose of 1310/cm into ^100& Si wafers. The wafers were subsequently annealed in either a rapid thermal annealing ~RTA! furnace or a conventional furnace for times between 1 s and 1 h at temperatures between 700 and 1150 °...

An interesting and satisfactory fluid model has been proposed in literature for the the description of relativistic electron beams. It was obtained with 14 independent variables by imposing the entropy principle and the relativity principle. Here the case is considered with an arbitrary number of independent variables, still satisfying the above mentioned two principles; these lead to condition...
