Toward a terahertz-driven electron gun
Femtosecond electron bunches with keV energies and eV energy spread are needed by condensed matter physicists to resolve state transitions in carbon nanotubes, molecular structures, organic salts, and charge density wave materials. These semirelativistic electron sources are not only of interest for ultrafast electron diffraction, but also for electron energy-loss spectroscopy and as a seed for...
متن کاملProtective and dosimeter design of the stationary and mobile model truck inspection system with electron linear accelerator radiation source
In this work, calculations of leaked dose from vehicle inspection area, the absorbed dose by driver and operator, and the required concrete thickness for shielding the inspection area are presented using the Monte Carlo code MCNPX2.6. The X-ray source of the present vehicle inspection system is a LinatronMi6 accelerator, end of which has only been simulated in this study (the electron beam coll...
متن کاملTerahertz radiation from laser accelerated electron bunches
Coherent terahertz and millimeter wave radiation from laser accelerated electron bunches has been measured. The bunches were produced by tightly focusing ~spot diameter '6 mm) a high peak power ~up to 10 TW!, ultra-short (>50 fs) laser pulse from a high repetition rate ~10 Hz! laser system ~0.8 mm!, onto a high density (.10 cm) pulsed gas jet of length '1.5 mm. As the electrons exit the plasma,...
متن کاملdesign of an analog fuzzy logic controller chip
fuzzy logic has been developed over the past three decades into a widely applied techinque in classification and control engineering. today fuzzy logic control is one of the most important applications of fuzzy set theory and specially fuzzy logic. there are two general approachs for using of fuzzy control, software and hardware. integrated circuits as a solution for hardware realization are us...
