Electron beam at the end of the linear accelerator
In February 2015, SOLARIS physicists managed to send an electron beam through the entire linear accelerator.
The beam is visible as a bright point in our photo.
To reach the end of the linear accelerator, the electron beam has to travel all the 40-meters way from the source (i.e. from the electron gun) through six accelerating structures. At the moment, the SOLARIS electron beam is the fastest (the most energetic) beam of its kind in Poland. At the end of the linac it reaches almost the speed of light (to be precise: 99.99985% of the speed of light), and its energy is 300 MeV. In Poland, electron linear accelerators are mainly used for medical applications. In these cases however, electron beams reach an energy of several dozen MeV only. Ultimately, the SOLARIS electrons will gain a maximum energy of 600 MeV.
