Deflection of beta part. – Risø source
Demonstrate the deflection of beta particles using Risø’s beta source.*)
Simple but engaging apparatus with permanent magnets.
The magnets can be rotated to invert the field, and they can also be completely removed.
Can be used on three levels: qualitative demonstration of the deflection of beta particles in a magnetic field, including the sign of the charge; simple beta spectrum, where the energy is determined by reading from a graph; detailed, relativistic processing of the beta spectrum.
Supplement to mounting bench 514100. *) Source is not included. Alternative versions are available – please see 514135 (for 12 mm cylindrical sources) and 514125 (for 25 mm disc sources).
