That's our lab, where Makoto is talking, from 0:45 to 1:06, and I walked through yesterday to find them filming there. In fact I'm typing this from directly upstairs. Anyway, alas I can't take any credit for contributions to the latest work. The mark II version of the apparatus removed the detectors which we whipped together for them in desperate last minute flurry a few years ago, replacing them with fancy high resolution solid state (silicon) detectors. And with my work in Japan, and now with the new electron beamline, I haven't been available to do anything for them, but at the same time, they currently have no need for our detectors. So I've been somewhat out of touch, but I'm going to catch up in about half an hour, as Makoto is going to give a talk about the new paper. A few points, though, on the current paper. Although the trap is able to hold the atoms for up to 15 minutes, they are still creating many more which they lose immediately. The numbers are better, but still very small: they now create about 6000 H-bar per sequence, and lose essentially all of them to anihilation immediately (with an energy release of around 1.8 �Joules). The trap then holds no more than 2 or 3 atoms, and those tend to be lost over the next few minutes, so that not many trials show any remaining after 15 minutes. There's lots of work to go yet before there's enough there long enough to do some of the more interesting tests. One advantage of the anihilation energy, though, is that there are some things that can be done with these tiny quantities, and even one atom will give a nice robust signal when it anihilates, so you can see where and when that happens. I'll know more about there plans in an hour or two. -Pete On Mon, 6 Jun 2011, D and N wrote: > Congratulations to Pete and his team, again! > > Hope you approve of this link. > > Natalia > > http://genevalunch.com/blog/2011/06/06/cern-loves-1000-new-lhc-record-and-antimatter-caught-for-1000-seconds/ > > > _______________________________________________ > Futurework mailing list > [email protected] > https://lists.uwaterloo.ca/mailman/listinfo/futurework > >
