SAND MPD Ar3 ๏ ArgonCube ๏ Pixelated LAr ๏ Photon Detection ๏ Multi-Purpose Detector ๏ Gaseous Ar TPC ๏ ECal ๏ Muon System (maybe) ๏ SAND ๏ 3D Scintillator Tracker ๏ Low Density Surround ๏ High Density Surround ๏ ArgonCube+MPD move
- ff-axis; SAND stays on-
axis
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

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

๏ Number of channels
not fully established

Requirements (in progress)

Triggering Modes
๏ Beam—easy ๏ Controlled Calibration (e.g. light injection)—easy ๏ Untriggered—Ar3 reads out literally everything ๏ Uncontrolled Calibration (e.g. cosmics)—harder ๏ How much? What topologies? ๏ How much buffer is needed?
8
Data Rates
๏ Ar3 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 Ar3 ๏ 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
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?
