“We hope that with a variety of technical refinements–such as slowing down the antiprotons as they enter the trap, cooling the positrons more before they interact with the antiprotons, and revising the mixing technique–we can make antihydrogen which is cold enough [to] stay in our shallow trap.”
The day when antihydrogen atoms by the hundreds or thousands are not only created but kept around long enough to study is growing closer.
There’s a lot of technical background to this article, so I’m not entirely sure where would be the best place to start in terms of de-jargon-ing it. Leave comments with your questions and I’ll try my best to clarify (though I’m still a beginner in this field). I’m hoping some posts for the SCI 101 page develop out of this! Most importantly: No question is too trivial.
