SCD Detector

Most basic one single channel electron multiplier detector to combine with PHOIBOS 100/150/225 hemispherical analyzer for XPS, UPS, ISS, LEIS measurements.

Channel electron multipliers with an extended dynamic range for extremely high count rate applications are used as standard. This device is a specially formed and treated glass tube which has the effect of multiplying a single electron at the input to a pulse of around 10E8 electrons at the output. Because of their low resistance, the extended range CEMs are suitable for extremely high count rates. A voltage between 2.5 - 3.5 kV across the cone and the tail-end initiates the electron multiplication. Electron multiplication is produced by the emissive layer along the inner surface of the channel. The gain is governed by the detector voltage and the condition of the emissive layer. Upgrades from single to multi channel detection can be performed on-site.
