Improvement of Heat-Treated Niobium Surface by In-situ Plasma Treatment Applied to Superconducting RF Resonator
C. Boutelaa, S. Gruszka, C. Cheney +11
A specific heat treatment at 300 C, named medium-temperature baking (Mid-T baking) is applied to superconducting radio-frequency (SRF) accelerating cavities to improve the quality…
Study of Nb Surface Under Ultra High Vacuum After Heat Treatments For SRF Cavities
C. Boutelaa, C. Craig, R. Laxdal +4
Specific heat treatments applied to superconducting radiofrequency (SRF) cavities, such as nitrogen infusion or Mid T baking, aim to improve the quality factor (Q0) at medium accel…
Insitu X Ray Photoemission Study of Nb Surface Under Plasma Cleaning During MID T BAKING For SRF Cavities
C. Boutelaa, S. Gruszka, C. Cheney +11
Specific heat treatments applied to superconducting radiofrequency (SRF) cavities, such as nitrogen infusion or Mid T baking, aim to improve the quality factor (Qo) at medium accel…
Performance of FPGA controller in ISAC-1 accelerator chain
K. Fong, X. Fu, Q. W. Zheng +6
The LLRF of five of TRIUMF's ISAC-1 accelerator cavities have been replaced by 3 similar FPGA based system with different operating frequencies. These LLRF use internal digital pha…
