Scientific Description
The Test Facility and a Synchrotron Radiation Source at KIT is operated by IBPT External Link (Institute for Beam Physics and Technology). The beam lines and laboratories are operated by the Institute for Photon Science and Synchrotron Radiation (IPS External Link), and Cooperative Research Groups (CRG) at the Institute for Biological Interfaces (IBG External Link), Institute for Solid State Physics (IFP External Link), Institute of Microstructure Technology (IMT External Link), Institute for Nuclear Waste Disposal (INE External Link), Institute of Catalysis Research and Technology (IKFT External Link) / Institute for Chemical Technology and Polymer Chemistry (ITCP External Link), and Max Planck Institute for Solid State Research (MPIfF External Link).

At Campus North at KIT a 110-m 2.5-GeV electron storage ring is located with a 53-MeV microtron and 500-MeV booster. The racetrack microtron accelerates the initially 90-keV electrons to relativistic kinetic energies of 53 MeV, which are then injected into a booster synchrotron. In the storage ring in the booster synchrotron, electrons are further accelerated to 500 MeV before final injection into the 110-m electron storage ring. Finally, the electron's kinetic energy is ramped from 0.5 GeV to a typical value of 2.5 GeV for the generation of mainly X-ray photons or various other energies are set during machine physics experiments. The latter include the study of novel operation modes like low-alpha operation. During low-alpha operation coherent synchrotron radiation (CSR) in the terahertz (THz) frequency range is investigated. The injector has a repetition rate of 1 Hz. Typically injection into the storage ring takes place once or twice on a work day. The 110-m electron storage ring is named Karlsruhe Research Accelerator (KARA). For details on energy, injection, lifetime, and beam current of the electron storage ring see current and past Electron Beam Status. The storage ring can be filled with an arbitrary, operator-defined electron bunch pattern ranging from a single-bunch (1) to multiple bunches (up to 184) spaced by 368 ns to 2 ns, respectively. Resulting synchrotron radiation leads to photon pulses with repetition rates from 2.7 MHz (1 bunch), 5.4 MHz (2 bunches), ..., to 500 MHz (184 bunches). The storage ring is equipped with state-of-the-art and advanced ps and fs electron and photon beam diagnostics.
