Silicon photomultipliers are an interesting alternative sensor of single photons. One of their biggest disadvantages is their huge background and sensitivity to neutron irradiation. The first one can be overcome by using a narrow time window in an analysis or during data acquisition. To maximize their signal to the noise a light collection system can be used which collects the photons from a larger area. By using this technique also the sensitivity to neutrons can be minimized.Several studies have been performed with the use of silicon photomultipliers for detection of multiple photons. In the present contribution, we will present a study of the impact of different neutron radiation fluences to the ability of silicon photomultipliers for detection of single photons.
We will show the I-V characteristics, waveform, pulse height and timing analysis of samples from several different producers irradiated to different neutron fluences.
