The charge readout electronics for DUNE's horizontal drift far detector achieve the required performance, as shown by tests in the ProtoDUNE-HD prototype.
A machine-rendered reading of the paper's core claim, the
machinery that carries it, and where it could break.
This paper describes the custom cryogenic front-end electronics built to read out charge signals from DUNE's large liquid argon time projection chambers. It reports test results from the 770-ton ProtoDUNE-HD detector that confirm these electronics meet the noise, signal, and stability targets needed for neutrino oscillation measurements. A reader would care because reliable charge readout is essential to distinguish rare neutrino interactions in detectors that will run for years underground. The work shows the design can handle cryogenic conditions without performance loss in the prototype. If correct, this supports proceeding with the full DUNE far detectors using the same electronics approach.
Core claim
The authors present the design of the charge readout electronics for the DUNE horizontal drift far detector and demonstrate, using data from the ProtoDUNE-HD 770-ton prototype operated at CERN in 2024, that these electronics attain the detector performance specifications required for the experiment.
What carries the argument
Custom-built cryogenic front-end electronics for charge readout in liquid argon time projection chambers, tested for noise, gain, and long-term stability.
If this is right
The DUNE far detectors can be instrumented with this electronics design and still meet the sensitivity goals for neutrino oscillation studies.
Charge signals from particle tracks in liquid argon will be read out with sufficient precision to reconstruct neutrino events accurately.
The prototype validation reduces technical risk for the much larger underground detectors.
Similar electronics approaches become viable for other large liquid argon neutrino experiments.
Where Pith is reading between the lines
These are editorial extensions of the paper, not claims the
author makes directly.
Successful scaling would also enable longer data-taking campaigns without frequent electronics interventions.
The design choices may inform readout systems for future detectors aiming for even lower thresholds or higher channel counts.
If the prototype results hold, DUNE could begin physics running on schedule with this hardware baseline.
Load-bearing premise
Performance metrics measured in the 770-ton prototype will scale without degradation to the full-size DUNE far detectors during extended cryogenic operation.
What would settle it
Observation of increased noise, reduced signal efficiency, or electronics failures in the full DUNE far detectors after more than one year of continuous cryogenic running would falsify the claim.
read the original abstract
DUNE (Deep Underground Neutrino Experiment) is a long-baseline neutrino oscillation experiment currently under construction, whose far detectors will be the largest liquid argon time projection chambers ever built. This detector design calls for custom-built cryogenic front-end electronics to attain the required detector performance. This paper describes the charge readout electronics that will be used in the DUNE horizontal drift (HD) far detector and presents performance results using data from the ProtoDUNE-HD detector, a 770 ton liquid argon time projection chamber operated at the CERN Neutrino Platform in 2024 that served as the final prototype of the DUNE HD design.

Referee Report
1 major / 1 minor
Summary. The manuscript describes the design of the charge readout electronics for the DUNE horizontal drift far detector and presents performance results (noise, gain, stability) obtained from data collected with the ProtoDUNE-HD 770-ton LArTPC prototype operated at CERN in 2024.
Significance. If the reported prototype metrics are confirmed to meet DUNE requirements and the design choices are shown to be robust, the work provides important empirical support for the electronics that will instrument the largest LArTPCs ever built. The use of real prototype data rather than simulation-only validation is a clear strength.
major comments (1)
[Section on full-detector integration and operation] Section on full-detector integration and operation: The central claim that the HD charge readout electronics attain the required DUNE performance rests on the assumption that ProtoDUNE-HD results (noise, gain, stability) will scale without degradation to the ~17 kt modules. No quantitative scaling model or analysis is provided for the effects of longer cable runs, higher channel counts, or multi-year cryogenic exposure, leaving the extrapolation unverified.
minor comments (1)
[Abstract] The abstract would benefit from explicitly listing the key quantitative performance metrics (e.g., ENC, gain stability) achieved in ProtoDUNE-HD rather than stating only that results are presented.

We thank the referee for the constructive review and for recognizing the value of the ProtoDUNE-HD data in validating the charge readout electronics design. We address the major comment on scaling below.

Referee: Section on full-detector integration and operation: The central claim that the HD charge readout electronics attain the required DUNE performance rests on the assumption that ProtoDUNE-HD results (noise, gain, stability) will scale without degradation to the ~17 kt modules. No quantitative scaling model or analysis is provided for the effects of longer cable runs, higher channel counts, or multi-year cryogenic exposure, leaving the extrapolation unverified.
Authors: We agree that the manuscript does not contain a dedicated quantitative scaling analysis, which is a valid observation given the paper's primary focus on the design and measured prototype performance. The ProtoDUNE-HD detector was engineered as a full-scale prototype of the DUNE HD module, employing identical electronics, comparable cable lengths, and the same cryogenic operating conditions. The measured noise, gain, and stability results therefore already incorporate the dominant contributions from these factors. We will revise the full-detector integration section to include an explicit discussion of scaling considerations, referencing the DUNE technical design report requirements and the built-in design margins (e.g., amplifier noise performance and shielding) that accommodate the modest increases in cable length and channel count for the 17 kt modules. Multi-year cryogenic exposure data are not available from the 2024 ProtoDUNE-HD run, which was limited in duration; long-term qualification is documented in separate DUNE electronics R&D reports.
revision: yes
Circularity Check
0 steps flagged
No circularity; performance claims rest on direct independent prototype measurements
full rationale
The paper describes the charge readout electronics design for the DUNE HD far detector and reports its performance via experimental data from the ProtoDUNE-HD 770-ton prototype. No mathematical derivation chain, fitted parameters renamed as predictions, or self-referential definitions appear in the central claim. The results are direct measurements of noise, gain, and stability from the prototype, which serves as an external benchmark independent of the paper's own inputs or prior self-citations. Self-citations common to DUNE collaboration papers do not bear the load of the performance validation here.
This engineering and performance report relies on standard electronics design principles and experimental data from the prototype; no free parameters, axioms, or invented entities are introduced in a theoretical sense.
