Spark detector for visualising alpha particles.
When alpha particles ionise the air in the spark detector's aperture, sparks can be both seen and heard. The transparent lid allows observation from several different directions.
The spark detector connects to a high-voltage supply such as 367060 (not included). Normal operating voltage is between 2 and 5 kV.
The spark detector can be placed directly on a table or mounted in ordinary stand hardware using the supplied mounting post.
Supplied with instructions and experiment ideas.
