The field normalization factor ASCALE for this problem is based
upon the calculated cavity length ZLONG = 1.77800000.
Transit-time factor integrals and partial derivatives with repect to k
TT = (1/V0)Int{Ez(z) cos k(z-Zc) dz} - tan(phi)(1/V0)Int{Ez(z) sin k(z-Zc) dz}
TT = T - tan(phi) S
T' and S' are partial derivative with respect to k.
T" and S" are second partial derivatives.
For symmetric half cells (Zs = Zc), the computations are done using
integration limits Zs to Ze, but reported results correspond to a lower
limit of integration equal to -Ze.
Integrals along logical row L = 1 [R = 0.0 cm]
between logical coordinates K = 17 and 25
Integration lower limit: Zs = 3.1750000 cm
Integration upper limit: Ze = 4.9530000 cm
Center of gap: Zc = 0.0000000 cm
Electrical center: Zec = 0.8644785 cm
Frequency for T integrals = 809.3950826 MHz
Wave number: k = 2pif/c = 0.1696367 radians/cm
Particle velocity: beta = 0.1728121
Structure wave number: k/beta = 0.9816250 radians/cm
V0 = Int{Ez(z) dz} = 4.11078E+05 V
E0 = (1/L)*Int{Ez(z) dz} = 2.31202E+07 V/m
Treating the problem geometry as a single full cell:
The single-cell results may not be useful for a multigap geometry.
