In original publication, Table 1 contains errors. The corrected Table 1 is presented below: (Table presented.) Table 1 Parameter Unit QWR HWR Frequency MHz 81.25 162.5 βOPT 0.051 0.13 Leff mm 186.5 236.3 Q0 109 0.24 2.3 QRs Ω 18.1 37.1 R/Q Ω 474 298 Eacc MV/m 6.1 6.6 Epeak/Eacc 6.0 5.5 Bpeak/Eacc mT/(MV/m) 10.8 9.6 According to the corrected Table 1, the following textual corrections should be noted: The effective lengths (Leff) for the QWR and HWR superconducting cavities are 186.5 and 236.3 mm, respectively, and their Epeak/Eacc ratios are 6.0 and 5.5, respectively. The Bpeak/Eacc ratios for the two cavities are 10.8 and 9.6 mT/(MV/m), respectively, and the required quality factor for the QWR cavities should be higher than 2.4 × 108 at 6.1 MV/m and 4.5 K. The required quality factor for the HWR cavities should be higher than 2.3 × 109 at 6.6 MV/m and 2.05 K. © The Korean Physical Society 2025.
