## Nice words for Neutrinos from P5 - 2008

- From the report
- The panel recommends a world-class neutrino program as a core component of the US program, with the long-term vision of a large detector in the proposed DUSEL laboratory and a high-intensity neutrino source at Fermilab.

## * with charge and light readout

- Develop confidence in the construction technology
- Develop confidence in the cost estimate
- Develop a reasonable cost device
*Do interesting and relevant physics on the way*
- These issues need to be treated over a multi-year time frame.
*Experience in Liquid Argon TPC technology exists in Europe through the ICARUS program - there is much less in the U.S**.*
- * with charge and light readout

- Massive detectors for Neutrino Oscillation and Proton Decay

## Use small test stands for specific issues;

- Measure contaminant effects of TPC materials
- Measure efficacy of contaminant removal filters
- Provide real signals for electronics development
- Build intermediate size detectors (1/3 ton (ArgoNeut),
-  200 tons (MicroBoonE) and few kilotons (LAr5))
- Stimulates and sets schedules for technology
- Forces integration of all aspects of experiment design
- Stimulates development of `physics’ software
- Builds collaborations
- MicroBooNE: BNL,Columbia, Fermilab, LANL, MSU, UTA & Yale.

## ArgoNeuT (Fermilab, MSU, Yale) is installing in the MINOS tunnel

- - it has Fermilab Scientific involvement and is aimed at collecting a large number (~20,000) of neutrino interactions;
- tests purification and electronics, development of pattern recognition, track reconstruction, event identification, physics analysis
- MicroBooNE has stage 1 approval and a growing collaboration (BNL, Columbia, LANL, Fermilab, MIT, MSU, St. M.C, UTA, Yale). Resources to be negotiated.
**LAr5**** is now (imho) *****the***** crucial project for the long-term neutrino future - **in particular for issues not treated by MicroBooNE such as the TPC and Cryostat
