Popis: The 400 MeV storage ring Euterpe is under construction. A quarter wave cavity (45 MHz, 50 kV) will accelerate the electrons. Due to space limitations the cavity length should not exceed 0.5 m. Therefore three special geometries are considered which have an 'electrical length' several times the physical length of the cavity. The first employs radial transmission line folding, the second longitudinal folding and the third capacitive loading of the transmission line. Transmission line theory is used to predict the cavity properties. Good agreement is found with SUPERFISH calculations. The capacitive loading option is superior considering its simplicity of construction and high shunt impedance. An LC equivalent circuit is used to model the impedance matching w.r.t the rf generator. Results are in good agreement with measurements on a scale 1:1 cold model. >
