Multi-Method Timing of Transient Radio Pulsars with the GBT350 and GBNCC Surveys
E. F. Lewis, M. A. McLaughlin, J. K. Swiggum +23
We present the timing solutions for three radio pulsars discovered with the Green Bank North Celestial Cap (GBNCC) and 350-MHz Green Bank Telescope drift-scan surveys. These pulsar…
High Gradient Tests of the Fermilab SSR1 Cavity
T. Khabiboulline, C. M. Ginsburg, I. Gonin +12
In Fermilab we are build and tested several superconducting Single Spoke Resonators (SSR1, β=0.22) which can be used for acceleration of low beta ions. Fist two cavities performed…
Fermilab experience of post-annealing losses in SRF niobium cavities due to furnace contamination and the ways to its mitigation: a pathway to processing simplification and quality factor improvement
A. Grassellino, A. Romanenko, A. Crawford +10
We investigate the effect of high temperature treatments followed by only high-pressure water rinse (HPR) of superconducting radio frequency (SRF) niobium cavities. The objective i…
Nitrogen and argon doping of niobium for superconducting radio frequency cavities: a pathway to highly efficient accelerating structures
A. Grassellino, A. Romanenko, O. Melnychuk +7
We report a surface treatment that systematically improves the quality factor of niobium radio frequency cavities beyond the expected limit for niobium. A combination of annealing…
PIII Project Overview and Status
R. Stanek, C. Boffo, S. Chandrasekaran +9
The Proton Improvement Plan II (PIP-II) project is an essential upgrade to Fermilab's particle accelerator complex to enable the world's most intense neutrino beam for LBNF/DUNE an…
