To document the damage to the GEMs due to sparking photographs have been taken of the surfaces. Two sets of GEMs have been mounted on testing frames:

• Version 0 was used for the isobutane tests and was retired due to constant sparking between the top of the large GEM and the bottom of the small GEM. Photographs were taken after the GEMs were retired. Photos: v0 small, v0 large
• Version 1 will be used for the P10 tests. Photographs were taken before the GEMs were operated. Photos: v1 small, v1 large
