A first prototype of the Muegamma drift chamber (DC) was built and
tested in a particle beam at PSI in October 2000.
Before the chamber test, several preampifiers were tested. A report is
Instructions on how to analyze the taken data can be found here.
The distance calibrations required for the analysis, can be found
Following pictures show the individual chamber parts:
The chamber was first tested in the lab:
Then the chamber was put into a dipole magnet in the PiM1 area at the PSI ring accelerator:
Data were taken using pions, electrons and muons at varying momenta:
