An injector testbed based on a direct current gun and an interchangeable very high frequency gun for superconducting continuous‐wave free‐electron lasers

Journal of Synchrotron Radiation, Volume 32, Issue 4, Page 838-848, July 2025.
An injector testbed for continuous‐wave free‐electron lasers based on a direct current gun and an interchangeable very high frequency gun is under construction. Its physical design and performance have been studied carefully.The continuous‐wave free‐electron laser (CW‐FEL), based on superconducting radiofrequency (SRF) technology with an electron bunch

Dark-matter halo mergers as a fertile environment for low-mass Population III star formation

, 2014
While Population III stars are typically thought to be massive, pathways towards lower-mass Pop III stars may exist when the cooling of the gas is particularly enhanced. A possible route is enhanced HD cooling during the merging of dark-matter halos. The

Isolation and Structure Elucidation of the Heterocumulene Anions [NCC‐L]− (L=CO, CS, N2)

Angewandte Chemie, Volume 137, Issue 13, March 24, 2025.
The cumulated 5‐atomic cyanodiazomethanide [NCCNN]− and thioketenyl anion [NCCCS]− were synthesized from the metalated ylide and ketenyl anion, respectively. Both anions exhibit unexpected stability, but with notable structural differences. While the cyanodiazomethanide features a distinctly bent geometry, the thioketenyl anion was found to be linear ...

Stereodynamical Effects by Anisotropic Intermolecular Forces

Frontiers in Chemistry, 2019
Electric and magnetic field gradients, arising from sufficiently strong anisotropic intermolecular forces, tend to induce molecular polarization which can often modify substantially the results of molecular collisions, especially at low rotational ...

New theoretical method for calculating the radiative association cross section of a triatomic molecule: Application to N2-H-

, 2013
We present a new theoretical method to treat the atom diatom radiative association within a time independent approach. This method is an adaptation of the driven equations method developed for photodissociation.

Water destruction by X-rays in young stellar objects

, 2006
We study the H2O chemistry in star-forming environments under the influence of a central X-ray source and a central far ultraviolet (FUV) radiation field. The gas-phase water chemistry is modeled as a function of time, hydrogen density and X-ray flux. To

Radiation-driven Destruction of N-heterocycles in the Presence and Absence of Water Ice

The Astrophysical Journal
Simple N -heterocycles are expected to be an abundant class of molecules within the interstellar medium, and increasingly complex heterocycles (e.g., nucleobases) have been detected within meteoritic organic material and in samples returned from the ...
