A versatile and transportable endstation for controlled molecule experiments
Wuwei Jin, Hubertus Bromberger, Lanhai He +7
We report on a new versatile transportable endstation for controlled molecule (eCOMO) experiments providing a combination of molecular beam purification by electrostatic deflection…
Controlled molecule injector for cold, dense, and pure molecular beams at the European x-ray free-electron laser
Lanhai He, Melby Johny, Thomas Kierspel +27
A permanently available molecular-beam injection setup for controlled molecules (COMO) was installed and commissioned at the small quantum systems (SQS) instrument at the European…
The Kinetic Energy of PAH Dication and Trication Dissociation Determined by Recoil-Frame Covariance Map Imaging
Jason W. L. Lee, Denis S. Tikhonov, Felix Allum +28
We investigated the dissociation of dications and trications of three polycyclic aromatic hydrocarbons (PAHs), fluorene, phenanthrene, and pyrene. PAHs are a family of molecules ub…
Specific versus Nonspecific Solvent Interactions of a Biomolecule in Water
Lanhai He, Lukáš Tomaník, Sebastian Malerz +6
Solvent interactions, particularly hydration, are vital in chemical and biochemical systems. Model systems unveil microscopic details of such interactions. We uncover a specific hy…
New source for tuning the effective Rabi frequency discovered in multiphoton ionization
Wankai Li, Yue Lei, Xing Li +10
The Autler-Townes effect due to near resonance transition between 4s-4p states in potassium atoms is mapped out in the photo-electron-momentum distribution and manifests itself as…
Single-shot MHz velocity-map-imaging using two Timepix3 cameras
Hubertus Bromberger, Christopher Passow, David Pennicard +10
We demonstrate the application of event-driven Timepix3-based detectors in combination with a double-sided velocity-map-imaging spectrometer to record the full 3D momentum of charg…
Water is a radiation protection agent for ionised pyrrole
Melby Johny, Constant A. Schouder, Ahmed Al-Refaie +5
Radiation-induced damage of biological matter is an ubiquitous problem in nature. The influence of the hydration environment is widely discussed, but its exact role remains elusive…
Spatial Separation of the Conformers of Methyl Vinyl Ketone
Jia Wang, Ardita Kilaj, Lanhai He +3
Methyl vinyl ketone (CHO) is a volatile, labile organic compound of importance in atmospheric chemistry. We prepared a molecular beam of methyl vinyl ketone with a rotation…
Spatial separation of 2-propanol monomer and its ionization-fragmentation pathways
Jia Wang, Lanhai He, Jovana Petrovic +5
The spatial separation of 2-propanol monomer from its clusters in a molecular beam by an electrostatic deflector was demonstrated. Samples of 2-propanol monomer with a purity of 90…
Pure Molecular Beam of Water Dimer
Helen Bieker, Jolijn Onvlee, Melby Johny +5
Spatial separation of water dimer from water monomer and larger water-clusters through the electric deflector is presented. A beam of water dimer with purity and a rotation…
