  1. Parkes ATUCReportMay 2008

  2. Stats • Scheduled observing time , Oct07-Sep08 • 83% • Downtime (last 12 months): • 1.1% system faults • 2.8% high wind

  3. Observer feedback • 25 reports last 12 months 9.7 (9.7) after-hours support 9.4 (9.4) quarters 9.7 (9.3) Admin support 9.4 (9.2) Overall rating -7.9 (7.4) for RFI (immunity from)

  4. Receivers • With new 16-26GHz receiver, can cover most of the spectrum from 1.2 - 26GHz Delivery of this receiver delayed • Methanol Multibeam problems In hand, but some lost time

  5. Pulsar/transient backends • Pulsar timing • DFB2 operational (1GHz x 2IF) • DFB3 delivered Feb 2008 (1GHz x 4IF) • Search mode • APSR currently in shakedown (~8Gb/s BBR) • Search mode for DFB3 • MB-DFB (new 13 beam search engine)

  6. APSR – the Delluge

  7. Pamela DFB3 APSR New Back- ends

  8. DFB3

  9. Spectral line • Multibeam correlator still the workhorse • 2048 or 4096 channels max for nb > 2 • Up to 16384 channels for single beam • DFB3: • 2 freq x 256MHz BW / 8192ch (time-binned) • s/w correlators possible (using CPSR,PAMELA)

  10. MB-DFB • Collaboration between Swinburne, Berkeley, Manchester, Cagliari, ATNF, Effelsburg • 13-beam filterbank search engine with higher spectral resolution. • Targets; MSPs, transients, relativistic binaries

  11. MB-DFB board (1 beam)

  12. PTF 12m testbed antenna

  13. Welcome: Chris HollingdrakeParkes VC manager
