        Yuri Zaitsev is an academic adviser at the Academy of
        Engineering Sciences. http://en.rian.ru/analysis/20070511/65348455.html
         
         
        A group of Russian scientists from Tomsk, Yekaterinburg,
        Nizhny Novgorod and Moscow have developed a series of
        unique compact generators capable of producing
        high-energy pulses of hundreds and even thousands of
        megawatts. This compares with the capacity of a major
        Soviet hydropower station on the Dnieper or an energy
        unit at a modern nuclear power plant. The new generators
        are sources of electromagnetic radiation rather than
        electricity. Their main feature is a capacity to produce
        enormous power in a matter of nanoseconds. The impulses
        can be generated with a very high frequency.  
         
        Vice President of the Russian Academy of Sciences (RAS)
        Gennady Mesyats recalled that the first high-current
        electron accelerators were developed in the U.S.S.R. in
        the 1960s. Ten years later, Soviet scientists learnt to
        generate powerful microwave nanosecond pulses. The
        current generators have no counterparts in the world. In
        effect, Russian scientists have made a breakthrough in
        what is called relativist high-precision electronics.  
         
        The pulse is primarily of interest for fundamental
        research. Reporting these results to the RAS Presidium at
        the beginning of this year, scientists emphasized that
        sources with super radiation effects can be broadly used
        in long-range high-resolution impulse-based radiolocation
        and in studies of non-thermal impact of powerful
        electromagnetic fields on radio electronic components and
        different biological species. Super-powerful pulse
        generators can test the reliability of radio electronic
        devices and the immunity of energy facilities to
        different impacts. They can imitate the interference
        caused by a lightning and even by a nuclear blast. Their
        tiny size and unique physical properties make their
        sphere of application extremely wide.  
         
        The electromagnetic pulse (EMP) is a product of a nuclear
        explosion. It puts out of action even those electronic
        control systems that have withstood the shockwave and
        reduces expensive smart weapons to scrap metal. There are
        different ways of generating electromagnetic pulses - for
        example, it can be produced by explosion-induced pressure
        on a magnetic field. Physicist Andrei Sakharov was the
        first to propose using this principle in a bomb in the
        1950s. Today, records in the size of an induced magnetic
        field, maximum current and properties of such
        "radiators" belong to Russian scientists. They
        surpass foreign counterparts by 10 times. Depending on
        what facilities the EMP is directed at, the damage radius
        can be from several hundred meters to kilometers. Without
        creating a shock wave and inflicting visible damage, it
        destroys all enemy electronic equipment. Moreover, unlike
        electronic countermeasures, electromagnetic weapons are
        capable of damaging radio electronic components even if
        they are switched off.  
         
        At present, the infrastructure and troops of many
        countries are stuffed with electronic equipment. It will
        be the main target for electromagnetic weapons. The
        destructive effect is produced by the high acceleration
        of the magnetic and electrical components of the EMP.
        They induce voltage changes ranging from 100 volts to
        10,000 volts in circuit networks and terminals of radio
        electronic equipment. The ensuing massive sparking of
        cable jackets, their contact to frame and the ground, and
        breakdowns in connectors put the equipment out of action
        and lead to fires and explosions. To understand this
        effect better, it is enough to imagine what will happen
        to your TV-set if there is a power surge - it will simply
        melt. The Americans were the first to use such weapons in
        combat, for instance in Yugoslavia. Some analysts believe
        that electromagnetic bombs would have given the United
        States a vital advantage in the early stages of the war
        in Iraq. They could have disabled not only Baghdad's
        control and communications systems, but also electronic
        components of missiles, even those located in deep
        bunkers. But the U.S. command chose not to use
        electromagnetic bombs for fear that they might disrupt
        its own radio electronic equipment in the area.  
         
        Today, many countries have electromagnetic weapons.
        Military experts predict a victory in future wars to
        those who will be ahead in electromagnetic radiation. In
        many cases, not only the military-industrial complexes
        but also different civilian organizations, research
        institutes and universities conduct studies in this
        field, thereby increasing the threat of radio electronic
        terrorism. For example, a broadband high-energy and
        compact wave source is sold without any restrictions. In
        several fractions of a second, it can burn down all
        electronic equipment at an electric power station,
        substation or control tower. A short intensive pulse can
        instantly paralyze data bases, financial centers and
        industrial equipment.
