Laser fluorescence detector schematic diagram

A schematic diagram of the liquid chromatography system and laser fluorescence detector Is shown in Figure 1. The key components of this analytical system are described sequentially In what follows ... 

Fig. 2. Schematic diagram of the apparatus. The superconducting magnetic coils create trapping potential that confines atoms near the focus of the 243 nm laser beam. The beam is focused to a 50 pm waist radius and retro-reflected to allow for Doppler-free excitation. After excitation, fluorescence is induced by an applied electric field. A small fraction of the 122 nm fluorescence photons are counted on a microchannel plate detector. Not shown is the trapping cell which surrounds the sample and is thermally anchored to a dilution refrigerator. The actual trap is longer and narrower than indicated in the diagram...

Fig. 2 Schematic diagram of free jet apparatus showing the positions of the lasers and the fluorescence detector. On the right side of the diagram, the timing sequence is illustrated for the excimer and dye laser as well as for the integrator gate.
