A wire chamber for educational purposes
  Gaseous detectors with sense wires are still in use today in small experiments as well as modern ones as those at the LHC. This short note is about the construction of a small wire chamber with limited resources, which could be used both as an educational tool and also as a tracker in small experiments. The particular detector type selected for this work is the so called "Delay Wire Chamber": it has only two output channels per plane and can be made fully gas tight for educational operations. The design can be made with free software tools, and the construction can be achieved by relatively simple means.
