Multi-Wire Spark Detector MkII
The Multi-Wire Spark Detector provides a memorable and dramatic demonstration of the ionising properties of alpha radiation, making one of the key concepts in Nuclear Physics both visible and audible. Fine wires suspended above a metal plate form two electrodes separated by a small air gap. When a high voltage is applied, ionisation caused by alpha particles triggers bright, audible sparks. Bringing an alpha source (e.g. Americium) close to the detector produces a dramatic display of sparking, clearly demonstrating the highly ionising nature of alpha radiation as well as its short range and low penetrating power.

Optics Bench Pair
This is an economical alternative to a mounted optical bench. Each of the acrylic components can be easily aligned against a metre rule (not supplied) so that distances between components can be easily calculated and investigations into magnification and focal length can be carried out.
