ATF2 breaks beam size records
by Nobuko Kobayashi
The world’s smallest ever beam size of 55 nanometres was achieved by the ATF2 facility at KEK, reported Nobuhiro Terunuma at the AWLC workshop held at Fermilab. And what is more, the results are reproducible, which means that for the ILC, a recovery after a short break would be no issue.
