Parkes Future Receiver Discussions
Naomi McClure Griffiths 11 July 2012


Parkes Receivers Interim (2012 2014?)

Need to address an:cipated receiver usage
· Group of Astros met in May to brainstorm future projects · Assume current instrumenta6on

Project summary
· Dominant receivers:
­ 10/50, Mul6beam, H OH

· 13mm, Ku and maybe Mars may be required to be iden6fied at TAC process
­ The possible major projects are specula6ve

· VLBI requirements overlap with H OH, 13mm and Mars
­ Note 6.6. GHz VLBI requirement could be replaced with 12.2GHz if ATCA upgrade pushed to 12.2 GHz

· Future discussions to focus on science cases for ~20cm PAF and wideband 0.7 4 GHz and 4 24 GHz receivers
­ Possible large projects in both bands

A NMMc G suggesGon
· Offer Mul6beam 10/50 and H OH every term · Rotate 13mm, Ku, Mars and Galileo on pre announced term schedule, such as:
TERM 13APR 13OCT 14APR 14OCT X X 13MM X X X X X GALILEO KU MARS X

Advice on prioriGes Parkes
Other opBons? Is it agreed that the high frequency mulBbeam is the lower priority of the three consideraBons? We are likely to invesBgate both, but if there was a preference for invesBgaBng wideband or PAF which would it be? We feel our wideband approach is less risky than the `all eggs in one basket ' consideraBon of the lower frequency receiver only. Comments.

Advice on prioriGes ATCA
For later, but start thinking now ­ the case for going to 12.2 GHz on the Compact Array
