100 MeV microtron for the Metrology Light Source at Physikalisch-Technische Bundesanstalt (PTB)

  • The Racetrack Microtron is a high efficiency electron accelerator featuring: High Compactness
  • Low energy spread
  • Low energy spread
  • Low beam emittance
  • Ease in operation

Danfysik has build a 100 MeV RTM the Metrology Light Source at PTB-Berlin that will be used as injector to a storage ring. The overall layout of the electron accelerator is presented in figure below, while its main parameters are listed in the below table.
The electron source to the RTM is a 90 keV thermionic Pierce-type diode gun providing an electron pulse of 3‑4 ms. After the electron gun the beam is deflected onto the axis of a multi-cell 3 GHz accelerating RF structure by a small 90░ achromatic beam line. The accelerating RF structure is a standing wave structure with an energy gain of 5 MeV in both directions. The beam is circulated through the linac with two large bending magnets until it reaches its final energy. The energy gain per passage of the linac is 5.3 MeV which means that the beam will pass 19 times before it is extracted at the full energy, 100 MeV by means of a septum magnet.

The RTM is designed with state of the art technology and some new features are

  • A full metal vacuum system to exclude parts to be exchanged due to radiation damage.
  • Only ion pumps are to achieve UHV and turbo pumps are used for roughing.
  • High stability RF system where we use solid state modulators for both the klystron and the electron gun.
  • Epics control system.
  • Remote control of linac and main magnet position for fast commissioning.
  • Extensive diagnostics for full control of the accelerator.
  • The whole accelerator is built by independent sub systems to ease design and construction as well as operation.
