s393/land02 workshop 2011

The workflow of the calibration-reconstruction loop with land02 will be illustrated by the gamma1 and gamma2 programs. The determination of the activity of a calibration gamma source by using random coincidences will be used as particular example.

Cosmic muons offer good possibilities to calibrate various detectors in the LAND-setup. Moreover, using them does neither require time for calibration runs, nor sources, as data can simply be collected off-spill during measurements. With their help the LAND detector timing offset is already calibrated. Using cosmic muons to calibrate the proton branch of the Crystal Ball is possible as shown...
