Description of the sensor
The heart of the AL54 radiation sensor is a custom PIN diode covered with a thin aluminum foil to
make it insensitive to light. Electrons (beta) and photons (gamma) easily penetrate the aluminum
foil. Alpha particles which interact with the aluminum foil generate electrons and photons that can be
detected by the PIN diode.
The analog output of the pulse charge amplifier can be connected to an energy spectrum analyzer
to detect radon decay products such as 218Po and 214Po.
An integrated pulse discriminator with temperature compensated threshold provides a true TTL
signal output for alpha particles, electrons and photons. The performance of the AL54 solid-state
sensor combined with its extremely low power consumption makes it an excellent choice for physics
lab experiments as well as cutting-edge designs.
