Laser-wire (LW) beam profile monitors will be very important beam diagnostic instruments for future very high energy/intensity particle accelerators to replace the use of traditional profiling techniques such as wire scanners or screens. LWs can be employed in synchrotron light sources, linear electron-positron colliders, and most recently H− ion accelerators.
The PETRA-III LW, a Compton scatt

For slow extraction from the SIS 100 synchrotron, the high energy beam transfer lines of FAIR accelerators demand for diagnostic devices for non-intercepting measurement of beam currents down to nA range. A Cryogenic Current Comparator (CCC) offers the required absolute and non-intercepting current. The current resolution of the CCC is only limited by the system noise, mainly originating from exte

We started to explore the possibility of using surface waves traveling along a single wire, a so called Goubau line, for improved bench testing of beam instrumentation. Since the electromagnetic fields resemble closely the fields of a particle beam, bench testing would become a lot more realistic using such a setup. Our calculations are promising and soon we will build a first prototype.

The Longitudinal Density Monitor (LDM) is primarily intended for the measurement of the particle population in nominally empty RF buckets. These so-called satellite or ghost bunches can cause problems for machine protection as well as influencing the luminosity calibration of the LHC. The high dynamic range of the system allows measurement of ghost bunches with as little as 0.01% of the main bunch

An electron beam excites higher order modes (HOMs) when passing through an accelerating cavity. These HOMs may adversely affect the beam quality and in the worst case result in a beam-break-up instability. It is therefore important to ensure these HOMs are well-suppressed and their effect on the beam is minimized by aligning the beam to the electrical axis of the cavity. Compared to the TESLA 1.3

Low energy beams are very important for many existing and future accelerator projects, but require development of new diagnostic methods as most of the standard high-energy techniques no longer work. The future facility for low-energy antiproton and ion research (FLAIR) is an example of an accelerator complex providing such diagnostically challenging beams. Its central machine, the ultra-low energ

Hadron therapy has proven to be a very sophisticated and precise technique in cancer treatment. A particular advantage of hadron therapy is the precise dose distribution, which can be limited exactly to the tumour volume, thus decreasing the dose in the organs at risk.

The tracking of low energy (<5A.MeV) heavy (Z>10) ions faces a major difficulty: these particles strongly interact with matter and their trajectories are then perturbed.
