Running an Open Source Why’s it so..big? Synchrotron Clinton Roy Me • X-rays scatter in air, so a lot of the beams are run in vacuum. This makes Physics everything..difficult. Synchrotron • Accelerators use a lot of power, they need to be cooled with water to stop BR—GHT them melting. Software • A lot of the filtering processes have to dump unwanted x-rays into blocks of Outcomes material, these blocks need cooling or they’ll melt. • The bigger the storage ring, the more x-ray beams can be produced, and the more experiments can be conducted at the same time. • The medical beamline is far away so it can spread out and scan the entire patient in one sweep. • Safety means things are cladded in thick concrete and lead.
