The ELBE linear electron accelerator (LINAC) was put into operation in 2001. It now consists of a thermionic injector and two superconducting modules, each employing two niobium 9 cell TESLA type cavities. The LINAC is capable of accelerating 1 mA up to 40 MeV. The electron beam is used to generate various types of secondary radiation (IR, Bremsstrahlung, x-rays) and particle beams (neutrons, positrons). Being a multi purpose machine with high demands on beam precision and stability and given the high average cw beam power, sophisticated beam instrumentation and machine protection systems had to be developed. Systems and methods to measure beam position, -loss, -energy and -current, energy spread, bunch length and emittance are described in this paper.
