- August 28-29, 2006  at LANL
- General
- Overview of Meeting Topics
- Overview of What’s happened since last meetingToday’s Agenda
- Proposed Goals for meeting
- Melynda Brooks
- Los Alamos National Laboratory

## General

- Visiting LANL, Dinner Monday night, Introductions
- Two Days to Cover 5 General Topics:
- Mechanical Design, Constraints, Integration
- LDRD-Specific topics – Sensors to Picture Frames
- Readout Plan for LDRD and FVTX – Chip Data lines to PHENIX DAQ
- FVTX-Specific topics – Status and Homeworks for DOE Review
- Simulations
- What we don’t plan to cover this meeting (but will soon):
- Lvl-1
- Ancillary systems, power and grounding in detail, though there will be some discussion in each session likely

## General – What’s happened since last meeting?

- Geometry, Mechanical
- FVTX tilted planesvertical planes (Hubert)
- Some more detailed geometry studies of PHX+sensor+HDI by Dave
- PR with HYTEC came through, mechanical starting
- IR envelope expanded, agreement that silicon systems will not be compatible with HBD so HBD no longer constrains space
- Electrical:
- Specifications document for readout DAQ put forth and in process of vetting
- Radiation environment studied in some detail by VTX, Dave, Mark
- Some electrical prototyping going on at Columbia and LANL
- Hiccup in PHX development path, but R. Yarema expects to be back on track in October
- PRs from LANL approved for Guilherme
- Physics/Simulation:
- Offline software developing
- Other:
- VTX underwent full CD0 DOE review--mechanical and other designs advanced, schedule more firm

## Goals for Meeting

- How to form successful collaboration amongst ourselves with 3 (or more) tightly interleaved programs:  LDRD, FVTX, VTX, PHENIX as a whole?

- Vital to come to agreement on individual and collective goals for projects

- Should come to agreement on communication and decision making paths to follow

## The Silicon Program in PHENIX, Interplay

- Barrel silicon (VTX), Forward Silicon (FVTX) and LDRD (iFVTX) schedules
- VTX construction start FY07, installation into IR end of FY09
- FVTX construction to start FY08, installation into IR end of FY10
- LDRD has ~1 year time window to take physics with the VTX in place, additional time possible outside of IR
- Early start by VTX means that a certain amount of our design will be impacted by VTX decisions already made
**Details in Walt’s, Dick’s talks, Eric can address electrical**
- FVTX and LDRD proposals both must produce physics AND assumed that LDRD would solve a certain amount of R&D issues for FVTX if it is to be a viable program, and if the LDRD is to fulfill LANL LDRD goals “early exploration and growth of creative concepts “

## LDRD Connection to FVTX

- LDRD pitch to Los Alamos Laboratory

- FVTX proposal relies on R&D provided by LDRD :
- ~$310k of R&D work deflected by LDRD as we expect to leverage readout R&D directly into readout for FVTX
- Start of project in FY08 and completion at end of FY10 is only possible by leveraging 2 prior years of R&D efforts from LDRD program
- We must agree to level of commonality between the two that allows us to fulfill promises to LDRD committee and FVTX proposal without unacceptably compromising either project

## Goals for each Session

- Some presentations for each session to make sure everyone is educated about status
- Significant discussion throughout and encapsulated at end to make sure everyone agrees to issues, action items, path forward.  Do we agree to goals for each subsystem?
- Understanding of cross-coupling of electrical-mechanical, LDRD-FVTX-VTX are critical to make each project successful.  Please try to participate in each session even if you are not directly working on the topic.

## Goals for Meeting - Mechanical

- Mechanical Design, Constraints, Integration
- Work priorities for Forward Silicon work (LDRD and FVTX), especially setting of milestones for HYTEC
- Agreement to scope of work for each institution, interfaces, where work must cross institutions
- Baseline space constraints
- Baseline cooling constraints
- Agreement on points of contact

## HYTEC Mechanical SOWs

- FVTX/LDRD task list worked up that allows to solve both problems at the same time, hopefully more efficiently.
- Task is to use common solutions as much as possible
- Once they get PO in place, first work will be on conceptual design for FVTX and then see how LDRD can best be incorporated into this design.  Expect reasonably fast turn-around once they have $

## Goals for Meeting – Front Ends

- LDRD, FVTX
- Definition or path to definition of electrical and mechanical interfaces for each
- Set timelines for achieving above
- Scope of work to be covered by each institution
- Specification of level of commonality between LDRD and FVTX electrical and mechanical solutions
- Must be ready for LDRD presentation on integration into PHENIX in September
- Must be ready for FVTX TDR document due January 2007:  form priority list for getting this ready
- Set homework assignments for each system

## Goals for Meeting – Readout DAQ

- Readout
- Agree to commonality between LDRD and FVTX
- Form one baseline solution for the readout from LANL and Columbia proposals
- Agreement on some component/language selections
- Specification of interfaces formed in more detail where necessary
- Division of labor determined
- Agreement to space options to explore for readout, pros/cons of each
- Agree on milestones for the near future

## Goals for Meeting - Collaboration Communication

- How much formality should we follow to make sure we are working toward the same goals?
- Electrical and Mechanical work:
- Interface specifications in written document
- Functional specifications in written document
- Presentation of proposals to group
- Consensus forming and decisions on paths forward
- Points of contact, PM involvement in communication stream
- Use of fvtx-l to keep full collaboration informed
- Posting of minutes from meetings
