The Linac consists of an electron source and two accelerating sections.
In the electron source (also called "electron gun") the electrons are pulled out of a cathode by applying a high voltage of 90 kV between cathode and anode.
The two accelerating structures are each 5.2 m long and operate at an RF frequency of 3 GHz. They increase the energy of the electrons to 100 MeV and their speed to almost the speed of light.
A 16 m long beam transport system, consisting of several magnets, guides the electrons towards the booster, into which they are injected with socalled kicker magnets. For diagnostic purposes the beam from the Linac can be deflected towards a beam dump.
The Linac has been built by the German company "ACCEL".
