Preliminary design of a Cavity Tuner for Superconducting Radio-Frequency Cavity
Ming Liu, Jiyuan Zhai, Feisi He +1
This paper introduces a newly designed cavity tuner for superconducting radio-frequency (SRF) cavity. Aiming to overcome the drawbacks of traditional tuning systems, like the limit…
Error analysis of vertical test for CEPC 650 MHz superconducting radio-frequency cavity
Lingxi Ye, Peng Sha, Zhenghui Mi +2
Hundreds of 650 MHz superconducting radio-frequency (SRF) cavities with high intrinsic quality factor (Q0) and accelerating gradient (Eacc) will be adopted for Circular Electron Po…
High Q and high gradient performance of the first medium-temperature baking 1.3 GHz cryomodule
Jiyuan Zhai, Weimin Pan, Feisi He +36
World's first 1.3 GHz cryomodule containing eight 9-cell superconducting radio-frequency (RF) cavities treated by medium-temperature furnace baking (mid-T bake) was developed, asse…
Design of new helium vessel and tuner for CEPC 650 MHz 2 cell cavity
Z. H. Mi, Z. Q. Li, P. Sha +8
CEPC will use 650 MHz cavities for the collider. Each collider cryomodule contains six 650 MHz 2-cell cavities, which is totally new. Therefore, new helium vessel and tuner are des…
Parasitic modes suppression in CW cold tests of 1.3 GHz 9-cell high Q cavities at IHEP
Zhenghui Mi, Feisi He, Weimin Pan +19
The CW RF test of 1.3 GHz 9-cell cavity in liquid helium bath at 2 K is a very important key point in the cavity procurement. Some problems can be found through the test, according…
Medium-temperature furnace bake of Superconducting Radio-Frequency cavities at IHEP
Feisi He, Weimin Pan, Peng Sha +16
Recently, heat treatment between 250 C and 500 C has been attempted to improve quality factor of superconducting radio-frequency cavities at FNAL and KEK. Experiments of such mediu…
Commissioning of te China-ADS injector-I testing facility
Fang Yan, Huiping Geng, Cai Meng +58
The 10 MeV accelerator-driven subcritical system (ADS) Injector-I test stand at Institute of High Energy Physics (IHEP) is a testing facility dedicated to demonstrate one of the tw…
Design of a 325MHz Half Wave Resonator prototype at IHEP
Xinying Zhang, Weimin Pan, Guangwei Wang +11
A 325MHz beta=0.14 superconducting half wave resonator(HWR) prototype has been developed at the Institute of High Energy Physics(IHEP), which can be applied in continuous wave (CW)…
Uncertainty of data obtained in SRF cavity vertical test
Feisi He
Vertical test is a commonly used experimental method to qualify Superconducting Radio Frequency (SRF) cavities. Taking the experiences at Jefferson Lab (JLab) in US for example, ov…
