Description: | Ionisation chamber for determining the range of alpha particles "and for observing the Bragg curve, i.e. the increase of the specific ionisation current at the end of the the track of an alpha particle." The chamber has an opening of 26 mm diameter, with an earthed screening mesh behind which an insulated mesh is supported which is kept at a voltage of 1 to 1.5 kV with respect to earth. In addition there is a collector which is insulated from the casing and connected to the input of a measuring amplifier via a screened cable. Can also be used with the Wulf electroscope.
