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
available in
PDF format.
-
Instructions on how to analyze the taken data can be found here.
-
The distance calibrations required for the analysis, can be found
here.

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:
