Investigation of the effectiveness of non-inductive `multi-harmonic' electron cyclotron current drive through modeling multi-pass absorptions in the EXL-50 spherical tokamak
D. Banerjee, S. D. Song, H. S. Xie +14
The effectiveness of multiple electron cyclotron resonance (ECR) harmonics has been thoroughly investigated in context of high current drive efficiency, generally observed in fully…
Performance assessment of helicon wave heating and current drive in EXL-50 spherical torus plasmas
G. J. Qiao, D. Luo, S. D. Song +7
Analysis of helicon wave heating and current drive capability in EXL-50 spherical torus plasmas has been conducted. It is found that the driven current increases with the launched…
Nitrogen Contamination Causes High Field Q-Slope (HFQS) in Buffered Chemical Polished SRF Cavities
D. Luo, K. Saito, S. Shanab
Buffered Chemical Polishing (BCP) was the most conventional polishing method for superconducting radio frequency (SRF) Niobium (Nb) cavity surface preparation before the discovery…
Multi-scale time-resolved electron diffraction: A case study in moiré materials
C. J. R. Duncan, M. Kaemingk, W. H. Li +16
Ultrafast-optical-pump -- structural-probe measurements, including ultrafast electron and x-ray scattering, provide direct experimental access to the fundamental timescales of atom…
Conformer-specific Chemistry Imaged in Real Space and Time
E. G. Champenois, D. M. Sanchez, J. Yang +17
Conformational isomers or conformers of molecules play a decisive role in chemistry and biology. However, experimental methods to investigate chemical reaction dynamics are typical…
A liquid helium target system for a measurement of parity violation in neutron spin rotation
C. D. Bass, T. D. Bass, B. R. Heckel +7
A liquid helium target system was designed and built to perform a precision measurement of the parity-violating neutron spin rotation in helium due to the nucleon-nucleon weak inte…
