Design of Rib for SVD2 Y.Yamada at SVD meeting on Apr. 19, 2001 • Gravitational sag of ladder • supported at both edge : sagS = 5wL4/384EI ~ 28mm for SVD1-3rd-layer • fixed at both edge : sagF = wL4/384EI ~ 6mm for SVD1-3rd-layer • w(N/m):line density, L(m):length, E(N/m2):Young’s modulus, • Design of Rib for SVD2 • Zylon : FRP with zero electric conductivity and E ~ 50GPa • sagF ~ 5 mm for 4th and 5th layer • same X0 (~0.16%) with BN rib in SVD1 (X0 : Si~9.4cm, Zylon ~26cm, CFRP ~24cm) • CTE : Si ~ 3106, Zylon ~ 6106, CFRP ~ 1106
