In the scope of the Facility for Antiproton and Ion Research (FAIR) project, several new synchrotrons and storage rings will be built. The existing heavy-ion synchrotron SIS18 has to be upgraded to serve as an injector for the FAIR accelerators. All

As it is planned to switch the heavy-ion synchrotron SIS18 from single- to dual-harmonic cavity operation after construction of the new Facility for Antiproton and Ion Research (FAIR), its closed-loop control system for the damping of coherent longit

The quality factors of the 20 cell, 3 GHz niobium cavities of the S-DALINAC are smaller by almost a factor of three compared to their design value. Combined with the limited cryogenic power of the helium refrigerator in use, this restricts the maximu

We report on a study of field emission accompanied by emission of light in a 20 cell superconducting niobium 3 GHz cavity of the S-DALINAC. The spectral power of the observed light could be interpreted as black body radiation at about 1500 K. The max

We report on the development and application of robust, inexpensive bremsstrahlung detectors, so called Compton diodes, for a photon energy from 5 MeV to more than 130 MeV . The detector signal is estimated from a simple analytical model and compared

In this chapter, an introduction to the basics of continuous-time feedback systems is given. For more detailed treatments, the reader is referred to textbooks such as [1–5]. A simple amplitude control loop serves as an example in the following sect
