CERN boffins not interested in Vatican - but have publicly speculated about planting an antimatter bomb in a government funding office
Thompson and his fellow boffins don't care, of course - funnily enough they have no interest in blowing up the Vatican and it would seem only a mild one in powering possible future starships. Rather, they hope by examining antimatter carefully to work out answers to such puzzles as where all the antimatter actually is - theory suggests there ought to be as much of it as there is regular matter, but actually it is outrageously rare.
And it certainly wasn't easy to get together even a few atoms of the stuff. Charged antiparticles - for instance an anti-proton or an anti-electron - can be snared relatively easily using electromagnetic fields. The boffinry community managed this ages ago. As the mass of an atom of antihydrogen is almost all in the single anti-proton nucleus anyway, you might say the heck with the positron (anti-electron) and just go with a load of antiprotons.
The downside of that, according to this excellent article by ALPHA scientist Jeffry Hangst - who perhaps worryingly was evaluating the possibility of delivering a functioning antimatter bomb, not to the Vatican, but "to the offices of your national funding agency" - is that containing charged antiparticles requires huge volumes of space.
Far from a handy portable vial, in order to contain a single milligram of antiprotons - good for a reasonably major blast equivalent to 50 tonnes of TNT - you would need a vessel 100 metres across.
Things are a bit better with actual atoms of antihydrogen of the sort just captured for the first time. These can still be contained electromagnetically despite the fact that they are not charged, as they have magnetic poles. Hangst says that one might theoretically get a milligram of the good news in this nega-hydrogen form into a mere 100-litre vessel - roughly the size of a keg of beer.
Unfortunately, as we now know from the ALPHA scientists' just-published paper, it's very difficult to get a magnetic grip on complete, neutrally charged anti-atoms - it can only be done even with the arse-kickingest magnets if they're moving very slowly - ie if they are extremely cold. According to Thompson, the antihydrogen must be chilled down to just a degree above absolute zero. Such temperatures are basically unachievable even for the superchill experts of CERN, well practiced in keeping the magnets of the Large Hadron Collider frozen down to single-figures Kelvin. Ultrahypercold containable antimatter atoms can only be obtained by evaporation, ie by throwing away most of the antimatter to cool the remainder.
As Hengst points out, if one were dealing with Dan Brown quantities of the stuff this would involve destroying one's lab many times over during production. Even if this snag could be somehow dealt with, the beerkeg antimatter bomb would still have to be wrapped in superconducting magnets and frozen down within a few degrees of absolute zero using liquid helium: in other words the associated apparatus would be the size of a large building. It would be more convenient to simply lug 50 tonnes of TNT along with you to the Vatican - or in the CERN physicists' case to their various national-government funding offices. (One notes the recent UK government decision not to cut science funding as part of the economic austerity package with interest in this context.)
Just to really give Dan Brown a good kicking, Hangst goes on to point out that even if the human race's top particle-furtling labs set themselves to producing antimatter as their main priority, making a single 50-tonnes-TNT-equivalent milligram of the stuff would be a time-consuming business: in fact it would take 300 billion years by his estimates. He concludes:
Back down to the sober reality here at CERN, we would be happy just to demonstrate trapping of antihydrogen in principle. This means initially trapping just a few anti-atoms ...
That at any rate has now been achieved: a great day for science, if not for Dan Brown (who cares) or the Starship Enterprise (more regrettable, but never mind).
