FIG. 7.

Spatial and timing response of two laser pulses emitted sequentially by two lasers, with wavelength and energy intercepted by the individual wires, and arriving at a timing interval . The position of the first beam was horizontally shifted by 3 mm with respect to the second one (see text).

FIG. 8.

Layout of the laser spectroscopy experiment of and , wherein the wire monitor is used to measure the profiles of antiproton and laser beams.

Image of FIG. 9.
FIG. 9.

The measured spatial profiles of a pulsed beam containing antiprotons (solid lines), and a laser beam of wavelength (broken lines), overlapped on each other. The intensities of the two beams are independently normalized to fit on the same figure.
