1. Need for the ATA SKA Development Facility
Some investigations can only be done on the ATA
Others would be most time- and cost-effective if done there.
Complete observatory infrastructure at Hat Creek:
antennas (interferometry)
signal path, correlator, internet connectivity
accommodation
technical and administrative support

2. Tasks unique to the ATA
Practical performance of interference mitigation techniques (large-N, shroud)
Large-N calibration and imaging studies, including polarimetric calibration
Stations size and performance: validation of simulations

3. Tasks best done using the ATA (time constraints)
ATA antenna and feed performance, and extension to higher and lower frequencies
Evaluation of alternative feeds
Construction and evaluation of other antenna prototypes (e.g. 12 meter)
Mutual coupling/shadowing studies

4. Other tasks that could be done at the ATA
Data transport and management (much remotely)
existing BIMA real-time data path to users
true remote observing (no operator)

5. ASDF: Berkeley roles
Organize and provide support for use of the ATA and Hat Creek Radio Observatory within the TDP
Conduct specific investigations as part of the TDP
Practicalities:
Travel, equipment, computer budgets at Berkeley
Support for accommodation expenses of visitors to Hat Creek
Substantial management at Berkeley

6. ASDF staffing 1 Manager (50% on project?)
1 FTE Engineer (50% mech / 50% RF/El.) (Berkeley)
1 or 2 technicians (Hat Creek)
2 Postdocs (Berkeley)
1 Admin. staff (Berkeley)
Engineer, technicians, admin would support all users of the facility.
Postdocs would primarily carry out specific pieces of the TDP plan

7. Berkeley-led projects
Bock, Welch, two postdocs, students?
ATA antenna and feed performance
Mutual coupling/shadowing studies
Large-N calibration and imaging studies, including polarimetric calibration
Practical performance of Interference Mitigation algorithms
Stations size and performance: validation of simulations

8. Comments on NAIC proposal
Two key TDP centers:
ATA SKA Development Facility
Hardware Development Group
Antennas, feeds, optics + mount, receivers closely linked
Would benefit from a coordinated effort and central management (Weinreb and Welch?)
Report directly to Project Director? Do these alleviate the need for an NAIC project manager
