\"\ud83d\uddf3\ufe0f\"<\/span>This study presents the design and development of beam diagnostic tools for the mid-infrared free-electron laser (MIR-FEL) system at the PBP-CMU Electron Linac Laboratory. The 25 MeV electron beam was optimized using ASTRA simulations to achieve beam parameters suitable for MIR-FEL generation. The diagnostic system was developed based on these optimized beam properties.<\/div>\n
\"\u26c8\ufe0f\"<\/span> A transverse emittance measurement system, consisting of two quadrupole magnets and a beam profile measurement system, achieved less than 20% measurement error for beams with transverse sizes below 2 mm.<\/div>\n
\"\u26c8\ufe0f\"<\/span> A bunch length measurement system, using a transition radiation (TR) station and a Michelson interferometer, enabled femtosecond-scale bunch length measurements. In this study, the effects of transverse beam size, beam splitter type, and radiator size on the accuracy of bunch length measurement were considered. A 6 mm-thick silicon beam splitter was found to yield the most accurate results.<\/div>\n
\"\u2728\"<\/span>These outcomes provide a practical and precise diagnostic framework for high-quality electron beam characterization, supporting improved performance in MIR-FEL systems.\"\u26a1\ufe0f\"<\/span><\/div>\n
