...weeks before, on Sep. 18, a competing group, called ATHENA, which also uses the accelerator at CERN, announced that they had succeeded in joining an antiproton and a positron. This group is composed of mainly European scientists, who had not been serious competition for the Harvard group before...
However, Gabrielse said that ATHENA’s success came in part from work Gabrielse had already done. He said that many of the devices and techniques used by ATHENA to create the anti-hydrogen—including the football field-sized machine used to trap and merge antiprotons and positrons—had been developed by ATRAP in years earlier...
...ATHENA member Alessandro Variola, a scientist from the Italian National Institute for Nuclear Physics (INFN), says that such borrowing of techniques from other scientists is a natural and necessary component of scientific progress. “You can mix a huge amount of…different experiences, different techniques. You must be careful to choose the techniques that allow you the best [results],” he says. “And surely, some of the techniques of Dr. Gabrielse were useful...
...also said that ATRAP and ATHENA experiments differed in several notable ways, including in methods of detecting the anti-hydrogen after creation and in the quantity of positrons used...
Gabrielse said that ATRAP had begun its anti-matter experimentation long before ATHENA...
