We present details on our newly established transportable endstation eCOMO (Endstation for Controlled Molecules). The apparatus has been designed for use at various photon sources for investigating the molecular dynamics of small molecules in the gas phase [1].
The endstation consists of three main parts: 1) An Evan-Lavie-valve-based gas source. 2) An electrostatic deflector for the gerneration of pure molecular samples [2]. 3) A double-sided VMI spectrometer coupled with the time- and position sensitive Timepix3 camera [3].
The endstation was designed to be highly transportable, with built-in transport wheels, adjustable height, integrated controllers, power supplies as well as water and gas lines for easy beamtime installation. Here, we discuss our first results on the UV dissociation dynamics of carbonyl sulphide (OCS) [4].
