Superconducting properties of thin film studied via the NMR of implanted Li
Md Asaduzzaman, Ryan M. L. McFadden, Edward Thoeng +10
We report measurements of the normal-state and superconducting properties of thin-film using Li -detected nuclear magnetic resonance (-NMR).…
Two-step laser resonant ionization spectroscopy of chromium
Romina Schulz, Ruohong Li, Julius Wessolek +3
At TRIUMF's off-line laser ion source test stand, stepwise resonant laser ionization spectroscopy of chromium (Cr) was carried out, to find an efficient ionization scheme suitable…
Collinear laser spectroscopy on neutron-rich actinium isotopes
Ruohong Li, Andrea Teigelhöfer, Jiguang Li +10
High-resolution collinear laser spectroscopy of neutron-rich actinium has been performed at TRIUMF's isotope separator and accelerator facility ISAC. By probing the $\…
RF phase effect in the ion-guide laser ion source (IG-LIS)
Ruohong Li, Maryam Mostamand, Jens Lassen
The effect of the phase between the radio frequency (RF) waveform driving the ion guide and the laser pulses generating ions on the intensity of the transmitted ion beam has been s…
Depth-resolved Characterization of Meissner Screening Breakdown in Surface Treated Niobium
Edward Thoeng, Md. Asaduzzaman, Philipp Kolb +12
We report direct measurements of the magnetic field screening at the limits of the Meissner phase for two superconducting Nb samples. The samples are processed with two different s…
