John Mitchell Nuttall John Mitchell Nuttall (21 July 1890 – 28 January 1958) was an English physicist, born in Todmorden. He is best remembered for his work with the physicist Hans Geiger, which resulted in the Geiger–Nuttall law of radioactive decay.
Digicon A digicon detector is a spatially resolved light detector using the photoelectric effect directly. It uses magnetic and electric fields operating in a vacuum to focus the electrons released from a photocathode by incoming light onto a collection of silicon diodes. It is a photon-counting instrument, so most useful for weak sources.
