The universe is made up of matter ,right? But just think of this line "when there is matter , what happened to the anti matter ? "
This line made the physicists to start work on the ANTI MATTER since 1995.
Matter in this universe is produced during the Big bang , then there is every possibility of even anti matter produced during the same big bang , right? So this idea led to the research over anti matter and Scientists chose the Hydrogen atom to find its anti matter i.e; antihydrogen ,consisting of an antiproton and a positron.
The ALPHA experiment at CERN succeeded in trapping some anti hydrogen atoms and the study of these atoms may produce us some interesting facts about the origin of the Universe. But unfortunately, antihydrogen atoms have a very short life expectancy but still ALPHA's latest paper reports that 38 anti hydrogen atoms have been trapped in the recent trap and this is quite enough to study the properties of this anti matter .
This short life expectancy of the anti hydrogen is due to the fact that there is a chance of the hydrogen atom getting mixed up with anti hydrogen ad annihilate it ; and again this can be avoided with the help of strong magnetic force , pulling away these matter and anti matter away from each other and thus the problem is solved.
"For reasons that no one yet understands, nature ruled out antimatter. It is thus very rewarding, and a bit overwhelming, to look at the ALPHA device and know that it contains stable, neutral atoms of antimatter," said Jeffrey Hangst of Aarhus University, Denmark, spokesman of the ALPHA collaboration.
Of course many more experiments were done in the previous years , just to produce these anti hydrogen atoms ; like the one in 1995 by the same CERN during the PS210 experiment and which resulted in producing nine and just nine anti hydrogen atoms.But unluckily, as they were extremely hot , they were not suited to the aimed study.
Then In 1999 CERN activated the Antiproton Decelerator (AD), a device capable of decelerating antiprotons from
3.5 GeV to
5.3 MeV but that is even a too hot situation for these studies to be carried out.
Then again , in 2002, the ATHENA and ATRAP experiments were carried out for the same.
This enthusiasm for anti matter dates long back and In 1965, a group of researchers led by Antonino Zichichi reported production of nuclei of antideuterium at the Proton Synchrotron at CERN.Almost during the same time, observations of antideuterium nuclei were reported by a group of American physicists at the Alternating Gradient Synchrotron .....
Recent data released by CERN states that, when fully operational, their facilities are capable of producing
107 antiprotons per minute.
So the recent result produced by ALPHA will lead this journey , further .
