1. First result with PAF on a big single-dish radio telescope X. Deng, A. Chippendale, S. Johnston, G. Hobbs, D. George, R. Karuppusamy ASTRONOMY AND SPACE SCIENCE 7 July 2016, ASA meeting

2. Project background Phased Array Feed (PAF) was designed by CSIRO Astronomy and Space Science (CASS) for Australian Square Kilometre Array Pathfinder (ASKAP); Michael Kramer from Max Planck Institute for Radio Astronomy (MPIfR) bought it for FRB searching; CASS and MPIfR employed me to follow the project; To make the system working on single-dish telescope:  We installed the system at Parkes during Chinese new year;  CASS is updating PAF system (software);  MPIfR and Jodrell Bank is working on FRB searching and pulsar timing mode;  Curtin is working on spectral line mode; To install the system at Germany:  We will remove the system from Parkes at October ；  I will move to Germany with the system by the end of 2016;  We will install it at Effelsberg after that. Result from PAF on Parkes | Dr. Xinping Deng 2 |

5. System overview 5 | PAF: 600 MHz DRX: 600 MHz BMF: 384 MHz 9 GPU nodes PAF: 188 ports, 94 ports each polarization; DRX: digitize different ports individually; BMF: correlation for beam forming; BMF: form up to 36 beams; Result from PAF on Parkes | Dr. Xinping Deng BMF: 1 MHz frequency channel; BMF: 108 us sampling; GPU: beam formed data processing;

6. Passband 6 | Chippendale et al., ICEAA 2016 Band 1: 0.7-1.2 GHz, CF 0.892 GHz Band 2: 1.2-1.5 GHz, CF 1.340 GHz Band 3: 1.35-1.7 GHz, CF 1.525 GHz Result from PAF on Parkes | Dr. Xinping Deng

7. System temperature 7 | Chippendale et al., ICEAA 2016 System temperature is around 50 K in all frequencies It is significantly better than ASKAP (around 90 K) Efficiency is around 0.8 in all frequencies Temperature over efficiency is around 60 K in all frequencies Result from PAF on Parkes | Dr. Xinping Deng On and off source observation with Virgo A to get system temperature

8. End-to-end system temperature 8 | Astronomers are more interested in end-to-end system temperature; Not finished yet due to packets problem; Will do it again when we get a stable system; Do prove that beam forming works as expected; PSR J0835-4510 (Vela): 3x3 Square Footprint on 0.215° Pitch, S1400 = 1.1 Jy, 42 MHz, 10 minutes Beam 1 Beam 2 Beam 3 Beam 4 Beam 5 Beam 6 Beam 9 Beam 8 Beam 7 Result from PAF on Parkes | Dr. Xinping Deng

9. Boresight pulsar observing 9 | Vela: full bandwidth, 10 minutes Boresight beam tracking with full bandwidth; Good signal to noise ratio; Dispersion as expected; Result from PAF on Parkes | Dr. Xinping Deng

10. Boresight pulsar observing 10 | PSR J0437-4715, polarization is not calibrated Boresight beam tracking with full bandwidth; Good signal to noise ratio; The effect of parallactic angle is observed in timing residual; Timing residuals dominated by “jitter” noise; Result from PAF on Parkes | Dr. Xinping Deng

11. Multiple pulsar observation 11 | Problem: PAF can not be rotated in Parkes focus cabin Can not rotate PAF to track outside pulsar; Outside pulsar drifts through beam; SNR changes significantly; Result from PAF on Parkes | Dr. Xinping Deng

12. Multiple pulsar observation 12 | Solution: track with different beams Form different beams to track outside pulsar; Make sure that no significant change in SNR; Result from PAF on Parkes | Dr. Xinping Deng

13. Spectral line 13 | H I gas in a young galaxy at z=0.44 Result from PAF on Parkes | Dr. Xinping Deng
