News: 1. Update on WBS 2. WBS next steps 3. Instrumentation FT status Sowjanya Gollapinni (UTK) Anselmo Cervera Villanueva (IFIC) Joint SP/DP CISC meeting October 27, 2017
Updated WBS ● We are version “v4” for our WBS. Latest version “v4a”. Please use the latest version. – https://docs.dunescience.org/cgi-bin/private/ShowDocument?docid=5609 ● Separate WBS files for SP and DP – This is the recommendation from the project office – We are a joint consortium and we will conduct our activities as such. The SP/DP separation is only for WBS as it makes things easier from the project side with e.g. costing. – In our case, SP is the first detector and DP is the second detector – Common SP/DP activities that occur only once are included under SP (see next slide) 2
Common Items Items common to both SP and DP are only included once in SP. In SP WBS, these items have “Common to DP” in their felds in orange. 3
WBS Levels – L0, L1, L3 ● L2 ● L0 Management (includes reviews & – SP – milestones) DP – Physics & Simulations – ● L1 Design, Engineering and R&D (includes – subsystem test facilities & QA) APA – Production Setup (includes tooling) – SP-ELE – Production (includes component – SP-PDS – production, assembly & testing) CRP – Integration (contributions to activities at – DP-ELE – global integration facility) DP-PDS – Installation (contributions to activities at – SURF) HVS – ● L3 DAQ – SC/CI Cryogenic Instrumentation – – 4 TC – Slow Controls –
WBS Levels – L4 ● L4 Purity Monitors – Thermometry (Dynamic & Static thermometers) – Cameras (cold & warm cameras, and light emitting system) – Gas Analyzers (with LBNF) – Liquid Level Monitoring System (with LBNF) – Cryogenic Internal Piping (with LBNF) – Slow Controls Hardware (including network & computing – hardware) Slow Controls Infrastructure – Slow Controls Software – Slow Controls Quantities – Local Integration – 5
WBS – immediate steps RRB meeting – November 2 nd ● Global WBS: The goal is merge all the WBS from all the consortia into a ● global WBS document which will be presented at the RRB meeting Institutional Interests: The next main step in the process is to attach ● institutional interests to specific WBS items where appropriate – It’s understood that not every WBS element will have an attached institutional interest at this point in time – Deadline: Tuesday, October 31st At the RRB, we will show pie charts that attempt to summarize institutional interests within each consortia (e.g. Pie chart on the left for APA) 6
WBS – immediate steps Please look at the latest WBS files and put your institution's name down ● next to items you and your group plans to contribute Any questions/concerns on the updated WBS or if something is not clear, ● please write to myself and Anselmo. We can schedule a Zoom meeting as needed. Can you meet the October 31 st deadline to get this information to me and ● Anselmo? Questions/comments/thoughts? 7
Other activities & Post-RRB (from Eric) The WBS prepared represent activities that will happen in 2020 for the ● construction effort of SP and DP We also need to prepare a list of R&D activities in 2018/2019 for producing – TDRs. Soon we will need to provide feedback on this item. Post-RRB The next major milestone for the consortia will be completing the Technical ● Proposal by April, 2018 Technical proposal will include ● Written description of proposed subsystems and any alternatives under – consideration Updated WBS and associated list of institutional interests – Initial subsystem cost estimates – Initial draft of schedule for construction activities – 8
Instrumentation FT Status Instrumentation Feedthroughs: Thermometers, Purity Monitors & Cameras ● As a response to our request for ports, we were asked to explore the possibility ● of using cable trays and bolts that are present at the top and bottom (all along the height for the corners) of the cryostat. – Purity Monitor folks (Andrew/Jianming) and Thermometer folks (Jelena/Anselmo) have been exploring this – Cable trays are in the corners and no FTs on top of them 9
Instrumentation FT Status ProtoDUNE First thing we are exploring by looking at ● fluid flow simulations is if the fluid flow at the corners a good representation of what is going on in the rest of the cryostat. For Purity Monitors: seems like the ● corner location is not an issue from fluid flow side. Also, not an issue in terms of mounting – the device. Near by ports and how we will route – cables needs more exploration For Thermometers: seems like corners ● are not good representation of what goes on in the rest of the cryostat Mounting is also a challenge especially – Dynamic T-gradient thermometers Talk by Anselmo on this – 10
