	abstract = {Electron guns installed in electron-cooling devices produce beams whose 2D profiles are variable. The profiles were measured at the test bench by passinga wire across the beam, while the electric current from the wire and the light radiation alongthe wire were monitored, as well as the position of the wire.},
