C199800100009 SAMPLE Helium gass in the cloud chamber C199800100010 DETECTOR Cloud chamber was used to detect charged particles. C199800100011 Cloud-chamber technique was capable of associating C199800100012 the inelastic protons with the various types of C199800100013 reactions that produced them since particle ionization,C199800100014 momentum of charged particles, and the number of C199800100015 charged particles per event could be determined. C199800100016 The cloud chamber was mounted between a pair of C199800100017 pulse-operated Helmholtz coils that produced a magneticC199800100018 field 7000 gauss transverse to the beam. The C199800100019 sensitive volume of the cylindrical cloud chamber was C199800100020 16 in. in diameter and 6 in. deep, and it contained C199800100021 13 atmospheres of helium with water vapor. Pictures C199800100022 were taken every 2 minutes.
