Title: Some numbers on the SLAC klystron windows

Abstract

The attenuation in our standard copper rectangular wave guides at 10 cm wave length is known to be 0.7 db/100 ft. If the wave guide were made of 70/30 Cupro-nickel, the same alloy the window sleeve is made of, the attenuation constant would go up by the inverse square root of the ratio of the conductivities (skin effect formula). Thus the attenuation constant would be ..beta.. = 12.8 10/sup -3/ m/sup -1/. The length of the sleeve L = 23 mm. Hence a piece of rectangular wave guide of equal length would, at 50 kW incident average power, sustain resistive losses = 2 P ..beta.. L = 29.54 Watt.
