Media Coverage and Outreach
The trapping and holding of antihydrogen produced extensive media coverage (alpha-new.web.cern.ch/trappedNews; alpha-new.web.cern.ch/trappedHbarNews). Swansea antihydrogen researchers appear regularly in the media and Charlton and colleagues write educational articles (Physics Education 40 (2005) 229, Physics Education 48 (2013) 212, with Welsh translation: iopscience.iop.org/0031-9120/48/2/212/media) and give public lectures, for instance at the 2013 Cheltenham Science Festival (www.cheltenhamfestivals.com/science).
We exhibited antihydrogen work at the National Eisteddfod (aided by an STFC “Science in Society” grant). Our presentation was broadcast on the Welsh language TV channel S4C and helped to attract 26,000 visitors to the Science Pavilion. We have also presented our antihydrogen research at the Urdd Eisteddfod each year from 2011, with an average attendance of 14,000 in the GwyddonLe (Science Tent). Outreach is also a core activity at CERN, where the antimatter facility is open for weekly public tours regularly led by Niels who is an official Antiproton Decelerator guide.
