Gordon Campbell, Premier of British Columbia, came to TRIUMF to officially open the newly-completed ISAC-II building. The Premier thanked the researchers and other TRIUMF staff who drive the pursuit and discovery of knowledge and acknowledged that advances in technology and development are born from this fundamental research. He went on to say, “We’re com- mitted to promoting excellence in research by providing the kind of infrastructure that allows this type of innovative work to take place.” His announcement was enthusiastically re- ceived by a large audience of TRIUMF staff and invited guests.
