Two and three electrostatic Lens Systems for focusing of charged particles (12 Oct 2007) Design of the focusing lens system has been done by using SIMION computer program. A beam of singly charged nitrogen ions of diameter 2 mm with energy of 3 keV was started at a distance of 50 mm before entering the lens system. In order to design this system, we studied it with different parameters with space charge of 0.1 mA. This study includes design and optimize of a two-and-three cylinder lens systems. In a two-cylinder lens system, the first electrode was set at zero volts and the voltage applied to the second electrode was varied from 0 to-8 kV. Influence of the negative voltage applied at the second electrode for the-two-lens system on both the beam emittance and the beam diameter has been investigated for singly charged nitrogen ion trajectories. Beam emittance and beam diameter as a function of the tube diameter have been studied. Also, beam emittance and beam diameter for a singly charged nitrogen ions as a function of the focusing points at a different distances measured directly from the end of the-two-lens system have been investigated. Influence of the atomic masses of the different elements has been studied on both the beam emittance and beam diameter. The same study has been done for the-three cylinder-lens system (Einzel-lens system).

Just What Is Surveillance Technology? (28 Feb 2007) The technology of surveillance equipment is continuing to advance at a very rapid pace. As a result surveillance equipment has become almost ubiquitous in retail stores, public schools, gas stations, and airport terminals all across the United States. There is a wide range of surveillance technology that is available on the market. Surveillance equipment ranges from wiretapping phone and internet based equipment to high tech facial feature recognition computer software known as biometrics.
Headsets (28 Feb 2007) People at home and in office settings are using cordless headphone sets more often than not because they allow a person the kind of freedom that corded phones and even cordless phones can't. Even though a cordless phone allows a person to move about freely, he or she is still faced with the challenge of keeping the chunky phone against their ear in order to be able to listen and speak to the person on the other end.
