The design difficulties inherent in Faltin rails at these frequencies are described. Measurements of prototypes and HFSS simulations are compared, to check the simulations, and show good agreement. The pickup impedance and signal output phase with respect to ions traveling at 0.83c are simulated and presented for the final design both with and without the use of damping material, showing the need to damp unwanted modes present in the beam chamber.
