Abstract:

Document tree for the RF frequency doubler. Each interferometer uses 2 frequency doublers within the ALS system. One is used to double 79.4 MHz to 158.8 MHz as an input to the ALS fiber distribution chassis, E1200138 (for driving the fiber AOM). The other is used in the vertex ALS DIFF detection, to double the VCO frequency before it is sent into the phase-frequency discriminator (T1400317).
