DRD Theme from 2021 ECFA Detector R&D roadmap
WP4.3 created responding to the following theme identified in the 2021 ECFA Detector R&D Roadmap.
DRDT 2.4 – Realise liquid detector technologies scalable for integration in large systems.
Dedicated developments should achieve applications of the previous DRDTs in future detectors ten to a hundred times larger, compared to the current state of the art, and allow coping with increased noise hit rates from detectors with sensor areas reaching 10, 100 and ultimately 1000 m2. This will have to proceed while addressing the step change in complexity, with decade-long construction, in underground or undersea environments, with handling of heat load, value engineering and industrial production.

Motivation and goals of WP4.3
Bottom-up approach. The input gathered during the Community Workshop in April 2023 was summarized into three sub-themes for the DRD2 proposal:
→ Goal 1: Development of mid-scale facilities for large-area readout assembly and characterization at cryogenic temperature
→ Goal 2: (Develop) Large-scale digitization technologies
→ Goal 3: (Develop) Large-scale joint integration tests
4
Goal 1: Development of mid-scale facilities for large-area readout assembly and characterization at cryogenic temperature
For consideration: merge D1 and D2 into “Photodetector and upgraded TPC-testing facilities”to reduce number of deliverables?

Institutions that pledged to Goal 2
This goal has lost several institutions that were not ready to sign the MoU.
→ We may consider absorbing it into the next goal.

WP4.3 Science
We plan to hold a WP4.3 quarterly virtual workshop, out of phase with General DRD2 meetings. Focused on progress report.
Our understanding is that the Shared Facilities WG will coordinate the proposal for CERN Neutrino Platform running (including NP02/NP04 –ProtoDUNEs– and the Cold Box).
We will work on interfacing with other DRD2 groups and other DRDs, as their R&D reaches the point to scalability.
→ Our guide to resolve overlaps is that “WP4.3 focuses on R&D just for scalability”.
We will explore the relationship with the US RDC process and the possibility of establishing direct communication with next generation of large detectors.
→ e.g. clarify deadlines to adopt R&D developed within DRD2 in their consortia.
