Ion Chamber

NearSys is experimenting with ion chambers as an affordable radiation detector for robots and near space. The designs under experiment can be found at Charles Wenzel's website,

The electronics are soldered to a perf board and shielded with a copper pipe cap. The electronics are bolted to the can of the chamber, making the ion chamber a very durable unit.

Currently, the ion chamber under study is being read by the READADC command. to my surprise, I have determined that 5.5 MeV alphas from Americiunm-241 can be detected by the chamber but not 4.5 MeV alphas from Uranium-238
