Abstract :
A high-power, free-electron laser, the Boeing Laser Subsystem (LSS) was designed. Among the considerations determining the wiggler beam tube cooling requirements was the heating caused by induced surface currents flowing on the inside of the beam tube. The expected heating is calculated. Additionally, the effect of pulse shape and length on the heating is investigated. Two methods are used to evaluate the power dissipated in the LSS wiggler beam tube.<>
