IT HAPPENS ONLY IN INDIA,
GREAT JOB MR. PARMAR
it is good to eat as many as vegetables and fruits (totally vegetarian), but my aurvedic doctor asked me to stop eating every...
it may now be possible to capture live pictures of atomic motions in a chemical reaction or marvel at a snapshot of early universe. An international research team is building two huge machines towards these.
"We have developed a novel microwave amplifier and ultra-stable microwave generator for one of the machines known as Laser-based Ultra-fast x -ray Source (lux) which will generate extremely small pulses of x -rays," says Subal Kar who led a team at the department of radio physics and electronics of Calcutta University with John N Corlett of Centre for Beam Physics, Accelerator and Fusion Research Division of University of California, Berkeley, us. The ultra-small pulses of x -rays can probe and shoot atomic motions in any chemical reactions.

help solve several mysteries
" lux will help biologists study the structures of cell membrane-bound big protein molecules, which are targets for designing many of the drugs," Kar says.
"We have also invented specially designed radio frequency (rf) cavities for muon collider which will churn out high energy neutrinos providing clues to many unexplained cosmic phenomena," he adds. Neutrinos (weighing less than a billionth of a hydrogen atom), a sub-atomic particle, is a vital constituent of the dark matter, which makes up 90 per cent of the matter of the universe. Muon particles are a kind of sub-atomic particle much heavier than an electron, which ultimately decay into high energy neutrinos inside the collider. Both the machines are being made in the us and should be ready by 2008.
The time delay between 'pump' and 'probe' is 10 to 50 femtoseconds (femtosecond equals a thousandth of trillionth of a second) at the end stations. "The ultra-stable microwave generator synchronises the time delay between 'pump' and 'probe'. It will help better understand photosynthesis, which is vital for future energy planning and agriculture," Kar says. lux will even snap images of proliferating cancer cells offering vital clues to their unbridled growth and novel anti-cancer therapies.
The bunches of muon particles (positive and negative) are then further accelerated in linac and immediately injected into the collider ring, where energy reaches hundreds of thousands of tera electron volts (1 tera electron volt is equal to 1,000 billion electron volts) triggering muons' decay into high energy neutrinos. "Such neutrinos can unveil secrets of neutron stars (dead stars) and exploding stars (supernovas)," says Kar.
The muon collider research started in 1998, with Lawrence Berkeley National Laboratory as the nodal laboratory, with Fermi Lab and Stanford Linear Accelerator Center of us and kek High Energy Accelerator Research Organization, Japan, and Research Center Karlsruhe, Germany.
