  2. 1. Recovery Plan Donation from CERN goes to orphans of the earthquake 9 May 2011 A donation of 53,280 CHF raised by employees and friends of CERN will go to Ashinaga, a non-profit organization which provides financial, educational and emotional support to children whose parents or guardians were lost or seriously injured as a result of the earthquake and the ensuing tsunami. The decision to donate to Ashinaga came after intimate discussion between Rolf Heuer, Director General of CERN, Atsuto Suzuki, Director General of KEK, and Shoji Nagamiya, Director of J-PARC. KEK would like to express our sincerest appreciation to those who support Japan, both in emotion ways and in terms of donations.
