Weblisted in Table 1. There are 9 modes in the first dipole band and 7 modes in each of the second and the third dipole bands. Two additional modes in the first band are due to the coupling of the 3π/7 mode to the HOM couplers. The mode patterns of these modes are show in Figure 6. The first and the second band dipole modes are below the beam pipe Webparameter for what concerns the -mode e.m. design but the cavity mechanical parameters are greatly affected by the equator shape: R>1 allows better stress distribution in the …
