radiation sensor information
Radiation sensor technology is an strategic line where iC-Malaga has developed a new and revolutionary sensor concept. The new technology developed permits to achieve high levels of accuracy in the measurement of the radiation together with a miniutarized package. It makes the sensor very useful for different kind of applications i.e. medical, personal dosimetry, space, defense and high-energy physics.
Features and Advantages
The radiation sensor developed by iC-Malaga is based on the Floating Gate (FG) principle. The sensor is able to detect the radiations that generate ionization on the FG (i.e. gamma or protons). The FG technology applied to radiation dosimeters permits to accomplish with four basic needs on a dosimeter:
1.- Linearity: up to 98% with 60Co source
2.- Integration: two sensors inside a 5 mm x 5 mm QFN package
3.- Easy-to-use: readout via Serial Peripheral Interface (SPI)
4.- Ultra-low power measuring: passive detection mode available
The minimum amount of radiation detectable by the sensor is about 0,1 mGy and the Total Ionizing Dose (TID) up to 200 Gy. The sensor can be used with no power supply and is capable of detecting the radiation (passive mode) and only must be powered to readout the data. Another mode where the sensor is powered (active mode) can be used to measure in real-time the radiation.
