- Abstract
- Sensitive experiments with low energy neutrons are being used as tests for physics beyond the standard model. A 1 MeV electron accelerator for use as a calibration tool for detectors in high precision neutron beta decay experiments is currently being constructed at Triangle Universities Nuclear Laboratory (TUNL). The adjustable potential allows electrons to be accelerated to energies across the continuous beta decay spectrum, which is an improvement over current calibration methods. In this thesis, the Pelletron charging system employed by the accelerator is described and the results of a high voltage test of the accelerator are reported. Furthermore, magnetic and electric field maps are produced for the accelerator and spectrometer that holds the detectors and electron transport through the accelerator and spectrometer is analyzed using the finite element analysis software COMSOL, showing the validity of the design of the accelerator.
