Raster vs TBPM/SEM calibration
In this directory some tools for
the calibrations of the Slow raster ADC value vs the TBPM/SEM
position can be found. Check the README file.
Farm Scripts
In this directory we have a collection
of scripts that are useful to do mass replay on the farm. Check
the README file.
Asymmetry calculation
In a technical note
(Postscript,
HTML)
the very general formalism for beam-target asymmetries is
evaluated for real world situations like non constant
polarizations and changing dilution facter.
A collection of scanned asymmetries for different kinematic variables.
Helicity pair studies
Asymmetries for a large number of helicity pairs were
calculated. Statistical tests were
done to check for nonstatistical behaviour of the distribution. A spectral
analysis was performed, doing a Fourier transformation to check
for hidden frequencies.
The second documents is a study of beam current asymmetries in the experiment. Looking at the distribution for helicity pairs it concludes that the behaviour is statistical and answers the question how much time is needed to measure the beam current asymmetry with a desired accuracy.
