The next stage is to mix them with about 75 million cold positrons.
At a temperature of 4.2 K, the trapped positrons are an ultracold plasma, a frigid collection of charged particles.
The techniques used to produce beams of low energy positrons can also be adapted to create beams of low energy muons.Advertisement
