13. EVLA Advisory Committee Meeting
Project Goals FY06
Retrofit 6 antennas to EVLA design and return to array for transition observations
Complete identification of first science observing modes and prioritize project tasks to complete them
Refine project schedule to insure close coupling between hardware and software deliverables where appropriate
Help clarify/define the final structure of the new e2e Division and its interaction with NRAO operations and projects
Repeat contingency and risk analyses with finer level of detail

14. EVLA Advisory Committee Meeting
Project Goals FY07
Retrofit 6 antennas to EVLA design and return to array for transition observations (for a total of 12 EVLA antennas)
Install prototype WIDAR correlator and begin test observations
Commission a science advisory committee to evaluate/prioritize potential descope options
Select final design of 3-bit, 4Gsps sampler and initiate its production

15. Actions on 2004 EAC Recommendations - 1
Overrun in contributed effort from the operations budget to the EVLA project
$2.1M charged to the project
Inadequate resources for EVLA e2e effort
10 FTE years ($1M ) provided by the project.
e2e Division created for entire Observatory
Additional effort devoted from operations budget.
Complete refinement of L-band OMT design
Done. Test results presented at recent FE CDR

16. Actions on 2004 EAC Recommendations - 2
Conduct a careful scientific trade-off study of descope options
Contingency comparable to last year, but low.
Detailed contingency analysis and scientific study of descope options will be undertaken in FY07.
Bring younger NRAO staff into debugging and commissioning activities.
Additional, younger staff actively engaged.
Additional staff to be hired in FY06-07.

17. Actions on 2004 EAC Recommendations - 3
For system tests, two sets of antenna electronics need to operate simultaneously in the electronics lab
Can currently simulate 2 central reference sources and 2 LO fiber links in the lab.
Opted to install modules in antennas for testing and observations.
Many problems are VLA-EVLA transition issues.
Scope of the M&C system, its science requirements, & interfaces are not clearly defined
M&C design document is nearing completion. Includes internal interface definition.
Software development plan completed (identifies code description, developer, and timeline).
Completed report characterizing information distributed in M&C system.
Mark McKinnon
EVLA Advisory Committee Meeting
May 8-9, 2006

18. Actions on 2004 EAC Recommendations - 4
No standards for M&C design and coding.
Biweekly code reviews.
CVS used for source and version control.
Maven for build environment. Standard nightly code builds.
No M&C test and integration (T&I) plan
In transition from VLA to EVLA, EVLA antennas work must work with existing M&C system
Longstanding T&I procedure in place and being used
Will develop formal T&I plan for correlator in the final M&C system.

19. Actions on 2004 EAC Recommendations - 5
Adequate design of the e2e system is lacking.
More resources assigned to e2e, and High Level Architecture (HLA) team has started the e2e design.
Identify and prioritize EVLA-specific requirements for CASA so that required resources can be identified
Post-processing requirements common and unique to ALMA and EVLA have been identified (e.g. wide-field imaging and calibration).
