… As the magnetic field falls, any antihydrogen held in the trap will escape and annihilate on …
we search for escaping trapped antihydrogen. In a systematic search for trapped antihydrogen…

… antihydrogen that is not confined, precluding detailed study of its structure. Here we demonstrate
trapping of antihydrogen … We note that extensive searches with ATHENA-type mixing 2 , …

… in recent years, and antihydrogen is now routinely created and trapped and a range of …
bring them together to create antihydrogen. Once formed, the antihydrogen has been detected by …

… trap in a 4-min cycle. Under normal conditions, the storage lifetime 16 of the trapped antihydrogen
is … from repeated cycles 15 to obtain hundreds of antihydrogen atoms in a few hours. …

… We conclude that the laser light has removed 58% ± 6% of the trapped antihydrogen atoms
… Our sensitive vertex detector allows us to search for evidence of annihilations during the 2 × …

Antihydrogen atoms ( H ) are confined in an Ioffe trap for 15–1000 s—long enough to … Increases
in the number of simultaneously trapped Hare critical if laser cooling of trapped His to be …

… We perform numerical simulations of trapped antihydrogen dynamics to model microwave
resonant lineshapes and transition rates, atom ejection dynamics, and the spatial distribution …

… As such, attention has focussed on maximising the trapped antihydrogen yield by preparing
cold, dense clouds of positrons and antiprotons, and devising means of mixing them to form …

… trapped antihydrogen, or by using trapped antihydrogen as a source in a magnetically
guided anti-atomic beam. As the interference signal decreases exponentially with half the decay …

… trapped anti-atoms reach the ground state. Further, we report the first measurement of the
energy distribution of trapped antihydrogen… the systematic investigation of trapping dynamics. …
