Photodetachment emittance scanner

Negative ions offer the chance to use a non-destructive method for emittance measurements with good time resolution and with a high number of phase space points. Due to the low binding energy of the additional electron (0.6eV for H--ions) LASER light with a wavelength between 600 and 1100nm will produce a sufficient number of neutral H0-atoms and detached electrons. The neutral beam has the same phase space distribution as the H--beam because neither the laser photons nor the recoiling photodetached electrons transfer a significant momentum to the H0-atoms. A dipole bending magnet separates the neutral atoms from the H--beam. The great majority of negative ions can be used for further applications; the neutral beam will be detected with a scintillator and a CCD camera to determine the emittance.
