Description

Since moving charges experience a force when travelling through a magnetic field, the presence of such fields can adversely affect charged particle detectors. The goal of our work is to characterize and eliminate magnetic fields from an electron spectrometer. To accomplish this, we are setting up a magnetic field sensor to detect the possible magnetic fields that are interfering with the spectrometer, specifically Earth’s magnetic field. The sensor and associated circuitry are being made compact, and we are automating the measurement process so that the sensor can used in the confines of the spectrometer. After determining the influence of the magnetic field, we will make use of mu-metal to layer and shield the spectrometer’s time-of-flight tube from unwanted magnetic fields, allowing the apparatus to provide accurate and unaltered results.
