Abstract
We have implemented a real-time method for bunch- by-bunch betatron tune measurements in the TEVATRON based on 16 bit 100 MHz ADC. To increase the betatron signal level from a pick-up we have used a modified version of Direct Diode Detector method combined with fast FPGA algorithm and a feedback loop utilizing a 14 bit DAC for suppression of low frequency beam motion. A description of this device is presented in this paper together with first results.
