Abstract The European X-ray Free-Electron Laser (XFEL) in Hamburg, Northern Germany,
aims at producing X-rays in the range from 0.25 up to 25 keV out of three undulators that can …

In recent years, superconducting radio-frequency (SRF) cavities have been considered as
candidates for qubits in quantum computing, showing longer photon lifetimes and, therefore …

The discovery of Higgs particle has ushered in a new era of particle physics. Even though
the list of members of the standard theory of particle physics is now complete, the …

Recently, heat treatment in the range of 250 C–500 C has been attempted with the aim of
improving the quality factor (Q) of superconducting radio-frequency (SRF) cavities …

Two 650 MHz single-cell superconducting radio-frequency (SRF) cavities used for the
Circular Electron Positron Collider (CEPC) were studied to achieve a high accelerating …

In this paper, the magnetic heating effect of the superconducting quarter-wave resonator
(QWR) cavities is investigated, and the Q slopes of the superconducting cavities are …

Performance of superconducting cavities are investigated with field emission effect and x-ray
detection. Conducting particles and surface curvature can cause field emission from the …
