Simulations for ProtoDUNE-ND LAr Component

ArgonCube 2x2 Demonstrator:

  • GEANT4 LAr simulation based on ArgonBox*

→ basic understanding of event shape and containment in 2x2

  • cryostat geometry included (by Chris/Rahul)
  • fjducial volume defjned for event vertices

–

30 cm from each side (~2x radiation length of LAr)

1.4 m 1.4 m 1.4 m

Simulations for ProtoDUNE-ND LAr Component

Downstream Tracker:

  • Repurpose existing detector components in the MINOS-ND hall
  • Example downstream tracker using a small portion of MINERvA:

–

12 Tracker modules: 24 x 2 cm CH planes

–

10 ECal modules: 20 x (2 mm Pb + 2 cm CH) planes

–

20 HCal modules: 20 x (2.54 cm Fe + 2 cm CH) planes

  • Simple GEANT simulation (by Chris/Rahul):

–

LAr cylinder + Fe cylinder + Al cylinder + Tracker (1.4 x 1.4 m2 sheets)

1.4 m

Simulations for ProtoDUNE-ND LAr Component

Neutrino Interactions:

  • high statistics GENIE* Monte Carlo sample
  • nly numu so far

→ nue under construction!

Beamline:

  • no beam-profjle

random vtx distribution within → 2x2

  • downstream tracker aligned with the center of 2x2

(maximum acceptance)

Containment Studies

  • Full event w/ and w/o muon
  • Showers

–

Pi0 → Roman Berner started working on a reconstruction algorithm*

–

EM (see backup slides)

–

Proton-induced (see backup slides)

  • Other topologies

–

Primary proton containment in the absence of mesons

–

Time-line for Fast* Neutron Tagging

  • Need a detaild photon propagation simulation for 2x2

→ defjne light-readout requirements

  • LArSoft ready for integration of geometries w/o wire planes (Kazu Terao)
  • First simple 2x2 geometry (GDML)** in co-op with Hunter Sullivan

–

implemented using NDGGD (despite lacking documentation)

** https://github.com/hcsullivan12/arc2x2ggd ** neutrons with energies > 1 MeV

Outlook

  • The main goal is to investigate which sub-sets of events we will be able to

easily contain in the ProtoDUNE-ND LAr component.

  • Containment plots as a function of hadronic energy.
  • Account for dead material (mainly tracker).
  • More sophisticated simulations will be performed as soon as new

geometries are available.

  • Photon propagation simulation for 2x2.
