Virtex-6 DFE – Status 2Gbyte DDR3 Memory Virtex-6 LX240T FPGA • New DFE board is working. • Newer Virtex-6 FPGA • Larger and cheaper FPGA compared to previous Virtex-5 based board. • Permits more room for Digital Signal Processing algorithms • Faster DDR-3 improves performance of MicroBlaze soft-core processor. • 4 boards received on 4/28/2011 • 90% tested. All major components working. (status as of 5/4/2011) • DDR-3 operating at 800Mbits/s • High speed serial links operating at 5Gbit/s • Gigabit Ethernet & FLASH memory working • Interface to AFE working. • 6 more boards expected on 5/18/2011 6 SFP Slots Gigabit Ethernet RS-232 1Gbyte FLASH Memory J. Mead & K. Ha

  14. RF BPM Electronics set up – Quantify BPM resolution Chassis M. Maggipinto B. Bacha AFE – Spin3 DFE – Virtex 6 PTC Synch clocks – Rev clock, ADC clock and RF clock

  15. BPM Electronics bench test – preliminary results (5/4/2011) • Sig gen (~500 MHz) to 1-4 splitter; Splitter output to BPM button inputs • Synch clocks – Rev clock = ~378 kHz; ADC clock= ~117 MHz • Collected 1 M samples of ADC data points; processed with moving filters TBT BPM resolution exceeds goals Y 2 kHz X 200 Hz K. Vetter

  16. BPM thermal drift test • Stability data taken during an overnight 11hr period in a thermally stable rack (0.1 deg C) • The RMS variation is 0.233 µm and 0.289 µm for X and Y respectively. • However, stability goals are 0.3 µm and 0.2 µm. • In-band pilot tone technique (next slide) will be used to meet stability goals. A. DellaPenna

  17. In band pilot tone technique - plan • Software development in progress to implement pilot tone based slow drift compensation • Injected pilot tone between 2nd and 3rd high-side revolution lines at ALS (2-Cam fill) • Measurement show pilot tone band along with revolution lines K. Vetter

  18. NSLS-II BPM test results w/ ALS Beam – (single bunch) • Test Set-up • One SR Button to 1-4 splitter • Splitter output to NSLS-II BPM • Single bunch I=23mA (15 nC) ADC sampled data One turn • Single bunch resolution • x = 9.64 microns • y = 10.3 microns • Meets NSLS-II goals

  19. NSLS-II BPM test results w/ ALS Beam – (multi-bunch) ADC sampled data • Test Set-up • One SR Button to 1-4 splitter • Splitter output to NSLS-II BPM • Multi bunch I= 500mA • Multi-bunch TBT resolution • x = 1.54 microns • y = 1.62 microns • Meets NSLS-II goals
