	In order to test 100 superconducting accelerator modules within two years three test benches have been created in the accelerator module test facility (AMTF) to achieve the rate of one cryomodule per week. Each RF station of the test facility consists of a 5 MW klystron, at 1.3 GHz, 1.37 ms pulse width and 10 Hz repetition rate, and a waveguide distribution system. Each waveguide distribution supplies RF power to eight cavities, four times a pair of cavities. The distribution allows for a maximum power of 1 MW per cavity when the distribution is switched to mode supplying power to only four cavities. A new type of 1 MW isolator and a new compact 5 MW power divider have been developed to achieve that goal. Several cryomodule have been already successfully tested with this setup. We present the waveguide distribution for this test stand and describe the performance of the different elements.

In order to test 100 superconducting accelerator modules within two years three test benches have been created in the accelerator module test facility (AMTF) to achieve the rate of one cryomodule per week. Each RF station of the test facility consists of a 5 MW klystron, at 1.3 GHz, 1.37 ms pulse width and 10 Hz repetition rate, and a waveguide distribution system. Each waveguide distribution supplies RF power to eight cavities, four times a pair of cavities. The distribution allows for a maximum power of 1 MW per cavity when the distribution is switched to mode supplying power to only four cavities. A new type of 1 MW isolator and a new compact 5 MW power divider have been developed to achieve that goal. Several cryomodule have been already successfully tested with this setup. We present the waveguide distribution for this test stand and describe the performance of the different elements.
