Then ionized electrons are drifted to anode wires (~ms)

Electrons near the wires are collected first, and electrons far from the wires are collected last, so drift coordinate information is converted to electron drift time (time is projected)

1. Why LArTPC? A candidate large neutrino detector

LArTPC vs Water Cherenkov detector - 6 times smaller mass LArTPC has same sensitivity with large Water Cherenkov detector for CPV - Using dE/dx and separation of vertex and photon conversion point, essentially no misID between single electron and photon conversion

300kt Water Cherenkov detector

50kt LArTPC detector

Energy loss in the first 24mm of track: 250MeV single electron vs 250MeV photon conversion


1. LArTPC all over the world

ICARUST600@Gran Sasso - physics run is ongoing at Gran Sasso

LArTPC@KEK- 250L LArTPC was beam tested

ARGONTUBE@Bern - goal is to demonstrate ~5m electron drift(210 stage Cockcroft-Walton inside of cryostat)

LEM-TPC@Cern- 2 phase TPC, LEM at gas region for X-Y information


1. Where are we? We need to demonstrate!

US path to future large LArTPC

2007 2008 2010 2013 20??

- The 0.7 ton ArgoNeuT was successfully completed. - We are ready for 150 ton MicroBooNE experiment. - future goal is the tenth of kilo ton detector (LAr40).

4. Why Argon?

Noble gas comparison - lower boiling point is easier to handle - higher density has more energy deposit - longer wavelength is easier to detect - Xe>Kr>Ar>Ne>He but Xe and Kr are expensive


4. MicroBooNE physics, Ds

Neutral Current Elastic (NCE) event (23k in TPC volume, 6E20POT) - MiniBooNE: no proton-neutron separation below 350 MeV (proton Cherenkov threshold).

- SciBooNE: hard to understand low energy protons (>200 MeV for analysis) .

- LArTPC can measure low energy protons (~40MeV protons corresponds to Q2 ~0.08 GeV2).

ICARUS collaborationPRD74(2006)112001

MiniBooNE collaboration,PRD82(2010)092005H. Takei,Fermilab-Thesis-2009-19

Ds, strange quark spin components in nucleon - Ds is Q2=0 limit of the isoscalar part of axial vector form factor of NCE events. - previous experiments (BNLE734, MiniBooNE) are limited Q2 > 0.4 GeV2.

4. MicroBooNE physics, coherent pion production

Recent data of coherent pion productions - No charged current coherent pion production is observed.

- Neutral current coherent pion production is observed.

Vertex activity - SciBooNE uses energy deposit around vertex (called vertex activity) to distinguish coherent and resonance pion production. - 3mm coordinate resolution of MicroBooNE allows fine pion measurement and vertex activity.
