Hello,

For the record, below is the information about the TDR that I sent to those responsible for chapters. I encourage everyone in the collaboration to offer them help and support in completing this important document.

TPC: Tom, Klaus, Takao, Jin
EMCAL: Craig, Sean, Anne
HCAL: John L., Megan, Stefan
CalEl: Eric, Steve
MBD: Mickey
DAQ/Trigger: Martin, Ed, Jamie
Simulation: Chris, Jin, Tony, Christof, John L.
Jet Structure TG: Dennis, Rosi
Upsilon Spectroscopy TG: Tony, Marzia

For the MVTX, INTT, and I³ (Installation/Infrastructure/Integration), I'll be in touch soon to negotiate how much information we include in the appendices.

Quick summary: We need to complete a draft of the TDR by about March
15 to be prepared for the upcoming reviews. You can delegate the
writing, but one way or another, it needs to be completed in March.

The instructions for the TDR are explained in detail here:

Don't panic--one of the required documents for PD-2/3 is the
submission of a Technical Design Report (TDR). The TDR is meant to be
a narrative description of what is proposed for construction. The
project it describes should match, as much as possible, the project
plans that have been developed and documented in the P6 RLS and the
corresponding BOE's. It is important that the system experts examine
and update the TDR for consistency with other documents that will be
available to review committees.

The project being reviewed at PD-2/3 is the MIE project, which
consists of:

- TPC and TPC electronics
- EMCAL
- HCAL
- Calorimeter Electronics
- MBD
- DAQ

The other components of the greater "project," the magnet, INTT, MVTX,
and installation/infrastructure/integration are very important and
will be reviewed as well, but not as part of the PD-2/3 review in May,
2019 and so will appear as appendices in this document.

Compared to the pCDR and CDR, many of the things that have to be
changed are to *remove* discussion of alternative technologies and
describe what is being built. Of course, some things should be
updated to reflect all the progress that has been made, but it is not
necessary to have yesterday's drawings incorporated in the TDR.
Thinking about the TPC and the DAQ have evolved significantly since
the CDR, they may need more work to update; the EMCAL, HCAL, CalEl,
and MBD need updating,

We're going to maintain the document in Overleaf again, and Overleaf
has changed a little since Overleaf acquired ShareLaTeX. It's not
perfect, and a large document like this is a little slow to recompile,
particularly at the happy moment when many people are working on it,
but the document looks good and is easier to organize than the
alternatives.

The fully editable document is here:

so be careful with it. If you just want to just see what it looks
like, the read-only version of the document is here:

I will update instructions in the Wiki, which were here for the CDR:

https://wiki.bnl.gov/sPHENIX/index.php/CDR

which has some useful hints-and-kinks for dealing with Overleaf.

If you plan to contribute text or figures to the TDR, contact me or one of the chapter authors.

Dealing with Descoping

We (Ed, Glenn, and I) have agreed that the way we will address descoping is:

For the detectors, the EMCAL and CalEl will start with sections describing the DOE scope, and the rest will describe the full scope. The HCAL will assume only OHCAL for the reasons below.

We should assume that the MVTX and INTT are there. They are not part of the MIE, but we have a documented plan for them to be there on Day 1.

The EMCAL plots can show the full acceptance now, since we also have a documented (if somewhat less mature) plan to instrument the whole EMCAL acceptance.

I think we have to leave out the IHCAL; we have a submitted proposal, but we really don't know whether it will go forward.
