Drone Rules for SIRIUS
The airspace over and surrounding the Sirius Particle Accelerator at the Brazilian Synchrotron Light Laboratory (LNLS) (Campinas, SP) is classified as a highly unique Strategic Scientific Infrastructure, High-Intensity Electromagnetic Shielding, and Advanced Research Protection Zone.
If you want ultra-niche, this is it. The Sirius Particle Accelerator, located within the Brazilian Center for Research in Energy and Materials (CNPEM) campus in Campinas, is the most complex and advanced scientific structural machine ever built in Brazil. It is a world-class 4th-generation synchrotron light source designed to accelerate electrons to near the speed of light, producing ultra-bright X-rays used to map the atomic and molecular structures of biological, chemical, and industrial materials.
Operating an unauthorized civilian drone over this highly specific, deep-tech research facility is strictly banned due to bizarre but critical technical factors:
Micro-Vibration and Structural Sensitivity: Sirius operates at a level of extreme atomic precision. The beamlines inside the accelerator require absolute structural stabilization, down to micrometer tolerances. The mechanical vibrations from low-flying drone rotors, or worse, a physical crash onto the massive ring-shaped roof structure, can impact highly sensitive nanometer-scale alignment experiments.
Intense Electromagnetic and RF Environments: Because the facility utilizes massive radio-frequency (RF) cavities and high-power electromagnets to bend and accelerate electron beams, the localized area experiences complex electromagnetic dynamics. A commercial drone flying directly above the main ring risks hitting concentrated RF interference, which will immediately jam the drone's civilian GPS and 2.4GHz/5.8GHz command links, triggering an unrecoverable flyaway or dead-drop crash.
Critical Research Asset Protection: The site conducts proprietary and highly classified research into new pharmaceuticals, state-of-the-art agricultural tech, and advanced defensive materials. Drone cameras flying overhead are heavily restricted to protect the intellectual property and competitive confidentiality of international research teams.
The CNPEM campus maintains strict on-site physical surveillance and real-time electronic perimeter tracking. Any civilian drone attempting to operate over the Sirius structure without direct clearance from the CNPEM Board of Directors and a tactical flight profile approved via DECEA's SARPAS NG will be instantly neutralized. Operators face immediate eviction from the campus, property confiscation, and federal legal charges for disrupting state-backed strategic scientific infrastructure.
