|Abstract:||Synchrotron radiation is commonly used in accelerators to monitor particle orbits. In most cases, these monitors are slow to read out and the digitizer's data typically do not include the information on individual particle bunches. After the announcement to upgrade KEKB to Super-KEKB, it was recognized that with a vertical beam-size of nanometers, to improve luminosity at the interaction point, there is a need for faster sampling and an ultra-low noise detector to monitor the beam and to determine beam-beam effects. The construction of the bunch-by-bunch X-ray Monitor (XRM) began in 2011, along with a new detector called Belle II. The University of Hawaii at Manoa was tasked with three detectors (KLM, iTOP, and XRM). An improved version with new XRM sensors, amplifier design and an improved electronics aims to address the weaknesses uncovered in previous XRM versions. This thesis covers the design details of the next generation of x-ray monitors, analysis from preliminary data collection at the local test stand, and the preparation done for testing at the KEK photon factory.|
