12. The advantage of using metastable CO in the present experiments is that these molecules are prepared with a pulsed laser at a well-defined time and at a well-defined position in a single quantum state with the appropriate Stark shift. By detecting the Auger electrons when the metastable CO molecules impact on the Au surface, the full arrival-time distribution of the molecules can be recorded in a single pulse, and the schemes to manipulate the longitudinal phase-space distribution demonstrated in Fig. 3, for instance, can be rapidly tested and optimized. Even though the detection efficiency for metastable CO is not as good now as it can be for ionization detection, the multiplex nature of the trap-loading and detection scheme already enables us to detect down to one metastable CO molecule per hundred traps on the chip.
