The 2pfg is run by a staff of researches, technicians and students. The researchers’ team is multi institutional with permanent positions for part of the staff while the other is composed by collaborative researchers. The permanent team usually is in charge of running the incoming projects while the collaborative team frequently takes the lead specialized tasks and also give guidance to the projects’ development to render the academic results into field applications. The technicians’ staff is in charge of the development and the construction of the mechanical devices necessary to the experimental work. At last, but not the least, the student staff is in charge of the execution of jobs in all areas of the projects. The undergraduate students stay engaged with the 2pfg for an average period of 12 to 24 months but, despite of the intermittent character, they are one of the most valuable resources that the educational institutions have. On the other hand, their engagement in the research activities helps them to enhance their professional skills while supporting the accomplishment of undergraduate works. The graduate students also work on the 2pfg's projects while, by its turn, the 2pfg support their thesis work in many ways since supplying bibliography, experimental facilities and computer resources among others. The scholarship are provided by governmental agencies as well as by project grants.
