Design optimization, commissioning, and uncertainty analysis of the quadrupole resonator system at Jefferson Lab for SRF material characterization
Mingqi Ge, Sarra Bira, Kristof Brunner +14
A quadrupole resonator (QPR) provides a sample-based platform for characterizing materials for superconducting radio-frequency (SRF) applications under controlled field, frequency,…
Electrochemical Polishing of Chemical Vapor Deposited Niobium Thin Films
Zeming Sun, Mingqi Ge, James T. Maniscalco +3
Combining chemical vapor deposition (CVD) with electrochemical polish (EP) operations is a promising route to producing performance-capable superconducting films for use in the fab…
CBETA Design Report, Cornell-BNL ERL Test Accelerator
G. H. Hoffstaetter, D. Trbojevic, C. Mayes +51
This design report describes the construction plans for the world's first multi-pass SRF ERL. It is a 4-pass recirculating linac that recovers the beam's energy by 4 additional, de…
Field-dependent surface resistance of a superconducting RF cavity caused by surface impurity
M. Ge, F. Furuta, M. Liepe +1
Q-slope issue, which is caused by the field dependent surface resistance, puzzled people for a long time in SRF fields. In this paper, we related the Q-slope with surface treatment…
A temperature-mapping system for multi-cell SRF accelerating cavities
M. Ge, G. Hoffstaetter, F. Furuta +6
A Temperature mapping (T-map) system for Superconducting Radio Frequency (SRF) cavities consists of a thermometer array positioned precisely on an exterior cavity wall, capable of…
Nitrogen-Doped 9-Cell Cavity Performance in a Test Cryomodule for LCLS-II
Dan Gonnella, Ralf Eichhorn, Fumio Furuta +13
The superconducting RF linac for LCLS-II calls for 1.3 GHz 9-cell cavities with an average intrinsic quality factor Q0 of 2.7x10^10 at 2 K and 16 MV/m accelerating gradient. Two ni…
