Samples were irradiated with reactor neutrons up to a fluence of 2.10(15) n(eq)/cm(2). The depletion depth was measured with Edge-TCT. The effective space charge concentration N-eff was estimated from the dependence of the depletion depth on bias voltage and studied as a function of neutron fluence. The dependence of N-eff on fluence changes with initial acceptor concentration in agreement with other measurements with p-type silicon. A long term accelerated annealing study of N-eff and detector current up to 1280 minutes at 60 degrees C was made. It was found that N-eff and current in reverse biased detector behave as expected for irradiated silicon.", optnote="WOS:000784713600004", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=5208), last updated on Sat, 07 May 2022 09:53:35 +0000", issn="1748-0221", doi="10.1088/1748-0221/17/03/P03030", opturl="https://arxiv.org/abs/2112.10738", opturl="https://doi.org/10.1088/1748-0221/17/03/P03030", language="English" }
