تکفیری جماعت داعش: افکارو اثرات: تجزیاتی مطالعہ

Since the past few years, muslims all over the world are being brutally accused of severe extremism. Many muslims now a days condemn terrorism and extremism and are not willing to connect these terms with the religion Islam. However there are a few who are in favour of these things. Terrorism is basically caused by a number of different acts of brutality. Its actually a chain reaction caused by the conspiracies against Islam, double standards of different super powers and injustice to the convicted and oppressed. Killings of the innocent and unarmed in the name of aggression is some thing which is totally against the Islamic teachings. Things become more complicated and dangerous when such acts of vandalism are done in the name of religion. Although many goals of ISIS are Islam based, however these very goals are achieved through non-Islamic ways. They feel no shame and go against all the ethics and moral values to reach their goals. Hence causing much more damage to their own muslim fellows. Even the cemetries are no more safe. They kill their opponents in the worst possible way and disrespect the dead bodies by kicking and hanging them to the trees. If this situation persists, it is inevitable that ISIS might replace the Halaku Khan and Genghiz Khan is brutality.

Design & Simulation of High Energy Thermionic Electron Beam Gun Accelerators Applications

Design, simulation and test of four types of thermionic DC electron beam guns; hairpin source, strip source, line source and disc source have been evaluated. Beam optics analyses were performed using SLAC electron beam trajectory program (EGUN) and CST Particle Studio (CST-PS). The guns are in diode configurations with planar geometry of the electrodes. The focusing electrodes were placed at the same potential of cathode without any extra biasing or Whenelt electrode. From these novel designs well focused and parallel beams of electrons with beam current (42mA-12A), emission density (5.04-6.72 A/cm2), power density (5.04×104-6.72×104 W/cm2) and normalized emittance (0.51-31.72 π-mm-mR) were obtained. The simulated results were verified by experimental tests at 10 kV of acceleration potential. The designs are simple and inexpensive. These guns are useful for metallurgical applications and for electron optical devices due to high current and power densities. Moreover, these are also useful for accelerator technology due to high emission and low emittance parameters
