Contract number DE-SC0006287 Many advanced accelerator concepts require the co-propagation and interaction of the electron with a laser (e.g., laser-plasma accelerators, inverse Compton scattering, laser heaters, and electron beam diagnostics with laser light). The strict requirements on beam properties necessitate numerical modeling to fully understand the complexities of the beam dynamics. Laser-specific simulations often require a different set of modeling tools. This has resulted in a hodgepodge approach, where the output of one program must be inputted into another. This paper presents the Radtrack software highlights, which aims to simplify these issues by uniting key software components under an intuitive graphical interface while addressing key problems relevant in the accelerator community.

	Funding: This work is supported by U.S. D.O.E Contract Number DE-SC0000870 The fiber-mesh diagnostic (FMD) is a transverse beam profile diagnostic based on the emission and detection of Cherenkov radiation produced as a relativistic electron beam traverses through an ordered bundle of fiber optics (SiO2), arranged in a hexagonal close-pack configuration. Sub-10μm transverse beam profile resolution is attainable due to fiber optic core concentricity. Adequate SNR is achieved using a standard CCD sensor. A fiber optic taper input maximizes light collection efficiency by coupling each output channel to approximately single-pixel pitch. A v-groove holder and assembly process was developed to hold many fiber layers in the desired configuration. In this paper, we present results from a fully functional FMD prototype evaluated at the BNL ATF facility that demonstrates the efficacy of this diagnostic.
