  2. The Near Detector etector Complex ๏ ArgonCube ๏ Pixelated LAr s, 
 ๏ Photon Detection SAND ๏ Multi-Purpose Detector Ar 3 ๏ Gaseous Ar TPC MPD ๏ ECal th ๏ Muon System (maybe) SAND MPD LAr ๏ SAND SAND MPD LAr ๏ 3D Scintillator Tracker ๏ Low Density Surround ๏ High Density Surround ๏ ArgonCube+MPD move off-axis; SAND stays on- axis � 2

  3. ArgonCube ๏ Segmented LAr to deal with pileup problem ~ 12M pixels in 35 ๏ modules ๏ Photon system adds another few thousand channels ๏ FEC design is well advanced; zero suppressed, low-rate readout � 3

  4. The MPD ๏ 10 bar argon TPC ๏ ~1M channels ๏ Surrounding ECal: 500k–2M channels ๏ FEC not yet designed � 4

  5. SAND ๏ 3D scintillator tracker ๏ Surrounding tracker+ECal ๏ Number of channels not fully established ๏ FEC not yet designed � 5

  6. Requirements (in progress) DUNE-doc-16988 � 6

  7. Requirements (in progress) � 7

  8. Triggering Modes ๏ Beam—easy ๏ Controlled Calibration (e.g. light injection)—easy ๏ Untriggered—Ar 3 reads out literally everything ๏ Uncontrolled Calibration (e.g. cosmics)—harder ๏ How much? What topologies? ๏ How much buffer is needed? � 8

  9. Data Rates ๏ Ar 3 has very low, but constant rate (zero suppressed!)—1.5 MB/spill (plus cosmics and Ar39 at 2.5 MB/s) ๏ Fast light system not zero suppressed—5 MB/spill ๏ HPTPC will likely be similar to Ar 3 ๏ ECal—dependent on final granularity ๏ 3DSTaK—0.12 MB/spill (Does not include low density and ECal) ๏ Final rates to be determined by final FEC designs and trigger choices ๏ Data gathering in progress—first time some groups have really thought about this, so figures are in flux � 9

  10. Plan Outline ๏ Baseline plan: use the FD hardware and software (with appropriate modification) ๏ Need to do some work to find out if baseline plan is feasible—do all of the components meet requirements? � 10
