1. By choosing a reentrant cavity design with a dielectric filling, a compact cavity with high shunt impedance, which is essential for measurements on low intensity beams, can be realized. (This PhD thesis)

2. Sometimes, accepting increased complexity in an instrument, such as the four-quadrant cavity BPM in this thesis, will provide a complete solution compared to a simpler instrument such as a pillbox cavity. (This PhD thesis) 3. The tuning of the monopole mode resonance frequency in a cavity resonator is relatively simpler when the cavity is designed with multiple pickups instead of a single pickup. (This PhD thesis)

4. The general perception of noise as a bad component in a system does not hold true for all practical systems.

5. Constructive criticism of certain cultural and traditional practices in agriculture along with intensive lobbying for new traditions will help in fighting global climate change.

6. A framework must exist to oblige case-based ethics courses in financial and legal institutes worldwide that will help in preventing large-scale corruptions. 7. The goal of equality cannot be achieved without addressing the systemic

For beam loss measurements at the coupling points of the gantries to the beamline, the halo monitors provide a beam current resolution of 10 pA with the lowest-detection threshold

Network analysis is performed to achieve maximum power transfer from the beam with a parametric investigation of the resonator dimensions such as pickup position, dielectric

The linear drives are used to position the stretched wire at multiple positions in order to measure the position dependence of the beam current monitor response and later

From the above observation, a cavity BPM built as a combination of four floating cavities offers a higher signal level for a given position offset and higher position

In addition, measurements were performed by sweeping the beam current at two different energies: 138 MeV and 200 MeV at a position offset of 4.8 mm to check the influence of
