2. CalDet Goal is to understand Detector Effects
Get calibration between Near and Far detector responses to same particle events
A CalDet effect that has not been analyzed is the light output dependence of the scintillator as a function of temperature
Near/Far Detector have consistent temperature
CalDet runs in the PS at CERN which has fluctuation ~10 oC

3. Temperature Calibration
First runs at the CalDet used only a RadioShack probe
Summer Thermocouple probes were added
RS Probe
Added temp probes

4. Necessity for Corrections
There is a .3%/ oC change in light output from scintillator
Oscillation parameters are dependent on energy, so proper energy resolution for events is required
CalDet goal is to get calibration to 1%
Take multiple runs w/ 1 GeV beam at CalDet while recording temperature with probes
With thermocouple temp Data get a handle on temperature corrections for previous data taken with only RS probe

5. Particle Detection
Death Star creating consistent energy particle beams

6. 1 Day

7. Temperatures plotted over 1 day
Probe 15 slope m=1.4824
Probe 16 slope m=1.5910
Ideally m=1

8. Getting There... A repeated 1 GeV run was taken over 5 days
Histograms of the 5 slopes (from each day) from 3 probes
Probe / Probe / Probe /

9. Future Work Electron neutrino analysis Difficulties
1-2% of muon neutrinos will oscillate to electron neutrinos
Examine Ө13 from electron neutrino events
Difficulties
Non-pure beam of muon neutrinos
Low event rate
Code-monkey skills are currently low
