1. 1. Optimization of Gammasphere Data Following the Nuclear Reaction 36Ar + 24Mg → 60Zn∗

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

   Author : Paul Böhm; [2023]
   Keywords : re-calibration; Gammasphere; 54Fe; Physics and Astronomy;

   Abstract : The experiment at Argonne National Laboratory aimed to study the fusion-evaporation reaction following the collision of a high-energy particle beam of 36Ar with a stationary target of 24Mg. This paper outlines the creation and implementation of an automated re-calibration procedure for the high-purity Germanium detectors comprising the Gammasphere array used for γ-ray spectroscopy in this experiment.

   Abstract : Synchrotron and Free Electron Laser (FEL) light is becoming an increasingly sought after tool for almost all scientific research aspects. MAX IV Laboratory introduced the first 4th generation light source that provides the brightest synchrotron light in the world. READ MORE

4. 3. Setup for residual magnetic field measurements in cryostats

   University essay from Uppsala universitet/FREIA

   Author : Carl Filip von Ehrenheim; [2018]
   Keywords : Cryostat; hall probe; magnetometer; pcb;

   Abstract : This thesis covers considerations regarding commercially availble magnetic field sensors and the design work and assembly of a 3-axis magnetic field sensor of Hall technology that is tested for use in a cryostat at the FREIA laboratory, Uppsala university. The assembled sensor needs to withstand cryogenic temperatures and a high vacuum environment. READ MORE
