Schematic of the coupling of the linear ion trap with the DESIRS beamline of the SOLEIL synchrotron radiation facility. VUV produced by the OPHELIE2 (HU640 type) electromagnetic undulator of the beamline is filtered by a gas filter, which removes the harmonic content of the source spectrum. The so-called `pink beam' with 7% bandwidth may either be sent to the experiment with the monochromator set at the zero order or it may be monochromated by the normal-incidence monochromator (NIM). Downstream, the beam is deflected and refocused by a mirror to the user port. The ion trap is mounted on the post-focusing arm port. A beam shutter is used to allow the incoming VUV light inside the trap for some controlled duration.
