Abstract: Background: Based on the Ring Delivery System (RDS), varian medical systems has unveiled HalcyonTM 4.0, a revolutionary medical linear accelerator with 4RPM. It has 6MV FFF photon energy, making it a real IGRT machine. It provides a very fast kV-iCBCT option along with regular planar and MV-CBCT imaging. This helps create better images and improves how we see soft tissues. A particular stacked and staggered double-layer MLC that allows for maximum modulation with minimal radiation leakage shapes the field portals. Our first Halcyon 4.0 machine was just put into service. This work's objective was to methodically examine a number of parameters of a recently installed Halcyon 4.0 linear accelerator. Materials and methods: In accordance with certain guidelines, precise measurements were made. Additionally, the measurements were taken in order to meet national regulatory standards. Halcyon 6 MV-FFF beam commissioning data was carried out in a water tank. An electrometer and 0.6-cc waterproof Farmer chamber were utilized for absolute measurements. Every relative measurement Using a CC13 chamber, (PDDs, in-line, and angular profiles) were carried out. Results: Every test was within the permissible range. Factory data were compared with the measured data. The outcomes were more than pleasing. Conclusion: The Halcyon linear accelerator commissioning experience is summed up in this paper. An assessment of mechanical, dosimetric parameters and radiation safety tests was conducted. The parameters that were obtained were significantly below the tolerance limits that were stated
