Particle beam diagnostics with micro- and nano-structured targets

At the Instrumental Optics Group we are conducting advanced research in the field of interferometric techniques for characterizing the transverse dimensions of particle beams in accelerators. Specifically, we are developing a novel interferometric approach based on the random intensity modulations generated by nanostructured targets, which enables highly precise measurements of beam size and distribution. This innovative interferometric technique leverages the unique properties of nanostructured targets to enhance both the resolution and efficiency of the measurement, offering new possibilities for optimizing beam control and manipulation for experiments in the X-rays sciences and high-energy physics. These research activities are also part of a collaboration among UNIMI, the ALBA Synchrotron Light Source and CERN, aimed at developing advanced beam instrumentation techniques for the Future Circular Collider (FCC), the flagship accelerator project at CERN for the post-LHC era to test the Standard Model of particle physics with unprecedented precision and push the boundaries of high-energy physics.
