We present details on our newly established transportable endstation eCOMO (Endstation for Controlled Molecules) for investigating the dynamics of small molecules in the gas phase [1]. The endstation consists of three main parts: 1) An Even-Lavie-valve-based gas source. 2) An electrostatic deflector for the generation of pure molecular samples [2-3]. 3) A double-sided VMI spectrometer coupled with two time- and position-sensitive Timepix3 cameras and the PymePix software [4-5]. We found a novel damped oscillation dynamics in the UV-IR(pulse duration are both 6 fs) ionization dynamics of carbonyl sulfide (OCS).
