On the first inertial-confinement-fusion ignition facility, the target capsule will be DT filled through a long, narrow tube inserted into the shell. {mu}g-scale shell perturbations {delta}m{sup '} arising from multiple, 10-50 {mu}m-diameter, hollow SiO{sub 2} tubes on x-ray-driven, ignition-scale, 1-mg capsules have been measured on a subignition device. Simulations compare well with observation, whence it is corroborated that {delta}m{sup '} arises from early x-ray shadowing by the tube rather than tube mass coupling to the shell, and inferred that 10-20 {mu}m tubes will negligibly affect fusion yield on a full-ignition facility.
