Configuration of the two position-sensitive cathode and three anode grids of the microwire monitor.
Schematic drawing of the (a) photocathode microwire monitor and (b) photograph of its interior with a grid installed.
Layout of the readout electronics of the microwire monitor.
Experimental layout to measure the profiles of two laser pulses with wavelengths .
Typical and profiles of a laser pulse of wavelength and energy intercepted by the individual wires on average, measured simultaneously by the (a)–(b) upstream and (c)–(d) downstream monitors.
Photoelectron yield from a photocathode wire irradiated with laser pulses of various energies and wavelengths (a) , (b) 266, (c) 355, and (d) 532 nm. Note different scales in the and axis.
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).
Layout of the laser spectroscopy experiment of and , wherein the wire monitor is used to measure the profiles of antiproton and laser beams.
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.
