A hybrid finite-element method/method of moments (FEM/MOM) model has been implemented to compute the coupling of fields into a cavity through narrow slot apertures having depth. The model utilizes the slot model of Warne and Chen [24]–[30], which takes into account the depth of the slot, wall losses, and dielectrics with air gaps in the slot region. The(More)
A new feedback system has been developed for stabilizing the SLC beams at many locations. The feedback loops are desi ned rate oft % to sample and correct at the 60 Hz repetition e accelerator. Each loop can be distributed across several of the standard 80386 microprocessors which control the SLC hardware. A new communications system, KISNet, has been(More)
