X100-7 Detector for Gamma Radiation

Source: First Sensor AG
First Sensor announces the new large area, low capacitance, and low noise X100-7 detector for gamma radiation. Based on First Sensor's low dark current and low capacitance silicon photodiode series, the new X100-7 detector has an active area of 100 mm² providing a large cross section for radiation detection. A special black epoxy encapsulant guaranties the blocking of light while maintaining small gamma ray attenuation. The X100-7 is offered in a ceramic SMD package as well as a ceramic 2-pin THD package in sample quantity up to high volume production. Applications include Ionizing radiation detector, medical equipment and personal dosimeters.

Recent nuclear events have raised awareness of risks from nuclear radiation and created a demand for commercial as well as personal radiation detection devices. Nuclear radiation meters based on silicon solid state detectors such as the X100-7 provide a reliable and inexpensive solution for radiation monitoring.

High performance solid state radiation detectors use the conversion of nuclear radiation into visible light by a costly scintillator crystal. However, inexpensive detectors rely on direct absorption in the silicon.

Since the probability of direct absorption of such gamma energies in silicon is relatively low, large area, low capacitance and low noise detectors such as the X100-7 are essential.

First Sensor offers the X100-7 both in a ceramic SMD package as well as a ceramic 2-pin THD package in sample quantity up to high volume production. Custom specific options including thicker silicon, fully depletable chip designs or scintillator coupled devices are available upon request. Please contact us for further details.
