1 Introduction This Statement of Work (hereafter SOW) will be the basis for the procurement of sixteen (16) charge readout plane support superstructures (CRP-SSTs) for the Deep Underground Neutrino Experiment (DUNE) Vertical Drift (VD) detector. This document outlines the Contractor’s responsibilities and obligations necessary for completing the requirements as set forth herein.

1.1 Overview

DUNE will feature two (2) “Far Site” liquid Argon cryostats, and these structures will be constructed in the Sanford Underground Research Facility (SURF) in South Dakota. Due to the different technologies used in the design of these experiments, each cryostat will require unique tooling and installation procedures for the assembly of all internal components.

Within the VD cryostat, two (2) of the main component systems are the central cathode plane and the upper/lower anode planes. The anode planes are integrated into charge readout planes (CRPs), and these components are mounted underneath the CRP-SSTs. At the horizontal midplane of the detector is an array of cathode modules suspended with Dyneema ropes from the CRP-SST frames. These frames are a critical structural component within this detector and require precision fabrication with strict tolerances.

2 Applicable Documents The document herein defines the statement of work requirements for the BSA VD CRP-SSTs. This document shall be read in conjunction with Brookhaven Science Associates (BSA) document BSA_VD_CRP-SST_SPC- 001 and technical specification drawings “2874228-01_-_FD2_CRP-SST-01_10-30-2025” & “2874228-02_- _FD2_CRP-SST-01_10-30-2025”.
