GEM Commissioning

The GEM shutter was opened for the first time on 12^th October 1999.

Below you can see examples of experimental data taken on GEM in the commissioning phase .

Thanks to the many experimenters whose data we show here.

Examples of Disordered Materials Data from GEM are available as part of the ATLAS-online manual.

For viewing the following examples of GEM data you will need to have version 4 of Acrobat Reader. This can be downloaded free of charge from Adobe's Web Site.

If you have version 3 of Acrobat Reader then unfortunately you will not be able to view the examples of GEM data.
