This thesis makes substantial contributions to our understanding of the statistical characteristics of undulator radiation through two experiments conducted in the Integrable Optics Test Accelerator (IOTA) storage ring at Fermilab. The first experiment focused on analyzing the turn-to-turn variations in the power of the radiation emitted by an electron bunch. The magnitude of these fluctuations is influenced by the 6D phase-space distribution of the electron bunch. The author presents the most comprehensive theoretical explanation of this effect to date, demonstrating its potential for measuring certain electron bunch parameters, such as size and divergence. Remarkably, this technique exhibits improved performance for smaller bunches and shorter radiation wavelengths, making it particularly advantageous for existing state-of-the-art and next-generation low-emittance high-brightness x-ray synchrotron light sources.

In the second experiment, a single electron was confined within the ring, releasing a photon only after a few hundred turns. In this regime, any classical interference-related collective effects were eliminated, allowing for a detailed investigation of quantum fluctuations. Additionally, the arrival times of photocounts were utilized to track the longitudinal motion of a single electron and to compare it with simulations. This served as an independent measurement of several dynamical parameters of the storage ring.

These groundbreaking experiments have significantly advanced our knowledge of the statistical properties of undulator radiation and have opened up new avenues for exploring and manipulating electron bunches in light sources. The results obtained in this thesis have significant implications for various fields, including high-energy physics, materials science, and medical imaging.
