sPHENIX is a new detector at RHIC.

Dear Berndt,

the sPHENIX proposal for an sPHENIX MAPS based micro-vertex detector (MVTX) 
can be found at:
https://www.dropbox.com/s/hr0js41pv3ej9kk/sPHENIX-MVTX-proposal-20180214.pdf?dl=0
(please let us know if you prefer a copy by email).

The proposal, led by the MVTX team from LANL, LBNL and MIT and the sPHENIX 
heavy-flavor topical group, describes physics motivation and performance, 
design choices and technical scope and deliverables for the proposed 
detector. Also included is a discussion of workforce, schedule and cost, 
which was prepared under the assumption that the proposal would be submitted 
for funding to DOE. We have not yet removed these sections, as they contain 
valuable information, but note that these aspects of the proposal will be 
reconsidered as we explore alternative funding scenarios. For the same reason 
we are not planning to make this proposal widely available, but expect to 
submit a shortened version focussing on physics and technical aspects to the 
arXiv later this spring.

Best,

Gunther and Dave
