1. 1. Characterization of neutron detection efficiency in a liquid organic scintillator

   University essay from

   Author : Ebba Wargh; Nadine Tabeshnia; [2023]
   Keywords : ;

   Abstract : Neutron detectors in the form of liquid organic scintillators are widely used for nuclear disarmament purposes. The main purpose of this thesis is to characterize the neutron detection efficiency of the organic liquid scintillator EJ-309 using Monte Carlo based simulations in the simulation program Geant4.

3. 2. Simulations of fission fragments in VERDI : A study of the Plasma Delay Time phenomenon

   University essay from Uppsala universitet/Tillämpad kärnfysik

   Author : Lovisa Rygaard; Andreas Ström; [2020]
   Keywords : ;

   Abstract : The purpose of this project is to study the plasma delay time phenomenon in preparation for the construction of the VERDI spectrometer. To accomplish this, simulations of the spontaneous fissioning process of Cf-252 were created using the fission code GEF, as well as MATLAB. READ MORE

4. 3. Implementation and characterization of Silicon detectors for studies on neutron-induced nuclear reactions

   University essay from Uppsala universitet/Tillämpad kärnfysik

   Author : Leo Lehtilä; [2019]
   Keywords : Silicon detector; Silicon telescope; Ultra-thin silicon detector; Energy resolution; Radioactive source; Am-241; Cf-252; Fission Fragments; Alpha Particles;

   Abstract : Energy resolution characteristics of silicon surface barrier detector signals amplified by different preamplifiers and spectroscopic amplifiers have been studied. The characterization has been done using alpha particles from an 241Am source and spontaneous fission fragments from two Cf sources. READ MORE

5. 4. Development and Characterization of Parallel-Plate Avalanche Counters for Nuclear Physics Experiments

   University essay from Uppsala universitet/Tillämpad kärnfysik

   Author : Matthias Carlsson; [2018]
   Keywords : PPAC; Parallel-Plate Avalanche Counters; Gas Ionizing Detector; Gas Amplification; Characterization; NFS; Radioactive source; Am-241; Cf-252; Fission Fragments; Alpha Particles; Time Resolution; Angular Dependence; Gas Pressure Dependence; Townsend Coefficient; PPAC Design; Manufacture; Manufacturing; Mylar foil; Aluminium Evaporation;

   Abstract : Parallel-plate avalanche counters, PPACs, are commonly used to detect fission fragments. The PPAC detects them and mark (very accurately) the time of detection. Such measurements can be used to measure the neutron energy (via time-of-flight) to study neutron-induced fission. READ MORE

6. 5. Study of the pulse shape as a means to identify neutrons and gammas in a NE213 detector

   University essay from Institutionen för neutronforskning

   Author : Mikael Höök; [2006]
   Keywords : pulse shape discrimination; pulse shape analysis; neutron; liquid scintillator;

   Abstract : This report describes investigations of the NE213-detector and the possibility to utilize pulse shape analysis to separate neutrons and gammas in a mixed emission field. Neutron fluxes are often contaminated with gammas, to which the detectors are sensitive. READ MORE
