– 83%

• Downtime (last 12 months): – 1.1% system faults– 2.8% high wind

Observer feedback

• 25 reports last 12 months9.7 (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)

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

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)

APSR – the Delluge

Pamela DFB3 APSR

New Back-ends

DFB3

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)

MB-DFB

• Collaboration between Swinburne, Berkeley, Manchester, Cagliari, ATNF, Effelsburg

• 13-beam filterbank search engine with higher spectral resolution.

• Targets; MSPs, transients, relativistic binaries

MB-DFB board (1 beam)

PTF 12m testbed antenna
