Abstract
A shielded cylindrical space-charge-limited diode ionization detector with high sensitivity and high resolution has been constructed to detect ionization in metal vapors, e.g., multiphoton ionization in the sodium atom and collisional associative ionization in the Rydberg states of the sodium dimer. The diode design and construction and measurements of its characteristics are described. Using this diode detector, a wide variety of high resolution spectroscopy can be obtained using techniques such as two-photon excitation, optical-optical double resonance, perturbation-facilitated optical-optical double resonance, and all-optical triple resonance.
