Scientific paper

Several improvements have been made on the apparatus developed in Brussels for the study of jet-cooled molecules, named FANTASIO, for "Fourier trANsform, Tunable, diode and quadrupole mass spectrometers interfaced to a Supersonic expansion". The upgraded setup, called Femto-FANTASIO, is presented.
These improvements include: a doubling of the pumping efficiency, by adding another turbomolecular pump Leybold MAG-W3200 CT; an increase in sensitivity in the 1.5 μm range thanks to a new CRDS system, consisting in new cavity mirrors, leading to a ring down time of 125 μs and a new detector, decreasing the noise level; a new injection system to probe samples liquid at STP conditions; a temperature controlled nozzle/slit; and as an alternative probe technique, an absorption source, tunable from 3000 to 9000 cm-1, coupling an optical parametric Oscillator (OPO), pumped by a Ti:Sa femtosecond laser, to a high resolution continuous scan Fourier transform interferometer. Femto FANTASIO will be used to investigate molecular complexes. First results and achievements of this new setup are presented.
