In this post we describe the measures taken with a Webcam used as “Particle Detector” using the application “Theremino Particle Detector”. Measurements have been made by placing the source close to the Webcam, the figure below shows the typical setup used. The following common sources have been used : Thoriated gas …

Introduction The purpose of this document is to describe the use of a commercial webcam as a particle detector. We will show that, from an ordinary webcam, one can make a “low cost” detector can detect beta particles, gamma radiation and cosmic rays. The device can be used to make …

In the picture you see the trace of a cone of Cherenkov light produced in the Japanese experiment Kamiokande, based on 50000t of water kept “observed” by 11000 photomultiplier tubes. The interaction of a neutrino with electrons or nuclei of water can produce a charged particle that moves faster than …

Most radiation detectors require pulse (or signal) processing electronics so that energy or time information involved with radiation interactions can be properly extracted. The objective of this post is to describe some solutions for the PMT / SiPM pulse processing in radiation detection.

In this post we describe a sensor for gamma rays based on a scintillator crystal with a well for housing the sample to be measured. This type of sensor allows to perform measurements with 4π geometry on small samples. With this type of sensor very high count sensitivity is achieved.

In this post we propose the construction of a fluorometer for measuring the concentration of DNA in a biological sample . The instrument is of quite simple construction and therefore can definitely become part of a biological DIY laboratory.

Introduction The Earth is being continuously bombarded by high energy particles from deep space. The particles are mainly high energy protons together with a small component of helium nuclei, heavier nuclei and electrons. The energy range is enormous with some particles having energies of the order 1020 eV.

In this post we propose the use of a detector based on a SiPM coupled to a plastic scintillator for the detection of cosmic rays. The detector we are going to use has been described in the previous post SiPM & Plastic Scintillator. To increase the security that logged events are …

In this post we propose the use of plastic scintillators coupled to SiPM for the detection of particles. A detector of this type is particularly sensitive to charged particles and thus can be used for the detection of cosmic muons and for the detection of electrons produced by β radioactivity.

In this post we are going to describe the use of the AdvanSiD preamplifier for silicon photomultipliers (SiPM). The SiPM were the subject of the following post : silicon photomultipliers (SiPM), in which the part of the signal amplification has been realized with discrete components.
