Introduction

Personnel

The following personnel assignments were agreed upon:

Principal investigator: Alan Dressler

• Vision
• Funding

Project scientist: Ian Thompson

• Maintains requirements document
• Decides science tradeoffs

Project engineer: Tyson Hare

• Maintains technical documents
• Manages shipping and commissioning

Project manager: Alan Uomoto

• Manages resources
• Presents reports to board
• Maintain interface control

Project name

After discussion about whether or not this should be an F/2-only project, the name became IMACS F/2 Mosaic Camera (but most thought that F/4 would remain an option if necessary).

Budget

A spreadsheet (BudgetImacsDewar2_051007.xls) was presented showing the dollar amounts listed in the proposal to the Magellan Council (August 2005, Dressler, Thompson, McCarthy, & Uomoto). No administrative support or contingency was included in this budget; Uomoto will add numbers before presenting it, and the MOU draft, to the Council.

It was noted that the E2V price quote will be in USD so exchange rate fluctuations will not be a problem or advantage.

Uomoto suggested a 10% be added for unanticipated overruns but others argued that the fixed costs were high and that a better number would be a flat $50,000K for contingency.

Uomoto reported that an account number will be created after Carnegie receives a signed MOU from the Magellan partners. The project can purchase things from the OCIW advance account but salaries must be reported directly to the project account. Uomoto asked people to track their time starting now.

Tyson Hare is not in the original budget for the project. We anticipate needing about 3 months of Tyson's time to build a new drawing package (checking for internal and external consistency) and for new design work on the focus mechanism.

Alan Bagish is not in the original budget but will be needed to design and implement the focus controller system. We will budget for one month of Alan Bagish's time.

Schedule

A simple Gantt chart (example presented) with progress bars will be used for Council reports.

A task list maintained in a WBS by Uomoto will be used for internal project tracking.

Technical requirements

A Technical Requirements Document is maintained by the project scientist. Hardware, software, operations, and performance requirements are tablulated, along with the scientific, operational, and/or cost drivers. Recording why certain requirements exist gives confidence when someone proposes relaxing them.

Requirements changes are announced immediately to project personnel, observatory management, and the observatory instrument scientist.

Task list

Uomoto will maintain a separate WBS for tasks. These were presented at today's meeting:

1. Gather mechanical info on platten
2. Re-design/extend dewar to fit platten
3. Check to make sure counter-balance still works
4. Re-design focus mechanism
5. Gather and review drawings for e-box
6. Submti drawings for e-box to shop
7. Start building set of PCBs and preamps
8. Order add-on parts--connectors, etc.
9. Discuss requirement for wing chips
10. Decide if non-N&S capabilty should be retained (this has an impact on cable & hose layout, and other things)
11. Decide on AR coating wavelength range
12. Re-design cooling strap
13. Understand the temperature control system needed (what does an E2V platten look like?)
14. MOU needs to be written and signed
15. TSIP proposal strategy needs to be worked out
16. Ask Mike Lesser for other CCD options?
17. Update budget to reflect total costs, contingency, and overhead

Actions

1. Thompson will contact E2V and initiate conversations on purchasing the detectors. There is a desire to get started on this early because detector acquisition is on the critical path.
2. Thompson will contact E2V to learn about their capabilities and product offering for the mosaic platten: what tolerances can they hold? Can they build in metrology features? What about temperature control?
3. Dressler will converse with Todd Boroson to get a better understanding of what the TSIP strategy should be.
4. Uomoto will update the budget
5. Uomoto will draft a Magellan MOU
6. Uomoto will draft the task list/WBS
7. Burley will prepare a cost estimate for the electronics
8. Thompson will decide whether or not it's worth conversing with Mike Lesser for other CCD options

Next meeting date

Thursday, December 8, 2005?
