Description

The CERN Accelerator School

in collaboration with the Faculty of Science, University of Split, is organising a topical course on

BEAM INSTRUMENTATION

Beam Instrumentation is essential in any particle accelerator. Beam diagnostics allows the proper operation of the accelerator and enables further optimisation to reach challenging performance goals.

This course provides a detailed understanding of how beam properties are measured and how the instrumentation is developed and operated. It is designed for laboratory and university staff and students, as well as manufacturers of accelerator equipment.

The course is divided into lectures and practical "hands-on" sessions.

  • The lectures focus on the typical diagnostics used in high- and low-energy linear and circular accelerators, together with application examples and elementary background on particle dynamics.

  • The “hands-on” sessions provide opportunities to work in small groups with real equipment used for beam position measurements, beam profile diagnostics, radio frequency measurements, and digital signal processing.

Who can apply?

The course is aimed at 

  • postgraduate students (ie. minimum of Bachelor’s degree or equivalent)
  • employees in accelerator laboratories, university departments and companies manufacturing accelerator equipment
  • engineers and scientists with a few years’ experience in accelerator physics, engineering, or related fields.

We welcome applications from all countries and nationalities. Applicants are responsible for ensuring that their registration fee and travel cost is covered by their home institute or employer, or, failing this, themselves. 

Early applicants will be given priority in the selection process. With a limited number of participants, we strongly advise you to apply early to secure your place. Waiting until the deadline may reduce your chances of being selected. Keep in mind that there is a limited number of single rooms available. Once the course is complete, we will close the registration. 

As usual, we will accept GRANT applications for participants from countries developing the accelerator field, which will otherwise have no possibility of taking part. Applications need to fulfill the same requirements as mentioned above. Further details can be found under ‘Apply for a Student Grant’.

 

 

We would like to express our gratitude to Euro-Labs. By sponsoring four extra grant students, they enable more talented researchers to join and benefit from our training program.

      Transverse beam dynamics recap I 1h

      The Advanced General CAS course is thought to be the continuation of the Introductory Course, which is held every year. Some of the students might not have had the chance to assist to this course and therefore on the first day a two hours recapitulation is foreseen. The main focus of this recapitulation is the theoretical description of particle motion in electromagnetic fields. Since the longitudinal motion is treated an an extra two hours recap, the main focus of this presentation is transverse beam motion, mathematical models, different accelerator types and collective effects.

      Measurement Principles I 1h

      Beam diagnostics and instrumentation are essential components of all types of accelerators. A wide range of beam parameters must be measured to observe particle beams with the precision required for tuning, operating, and improving the machine. The fundamental mechanisms by which information is transferred from beam particles to the detector are described in order to derive suitable performance characteristics for the relevant beam properties.

      Longitudinal beam dynamics recap 1h

      This talk gives a short review of longitudinal beam dynamics for both linear and circular accelerators.
      It covers the basics of acceleration in a linac. For radio-frequency (RF) acceleration, it introduces the concepts of synchronicity and the oscillation around the synchronous particle, including the criterium for stability of the oscillations.
      For circular accelerators, the lecture focuses on synchrotrons, their operation principle and their longitudinal beam dynamics. It reviews the synchrotron oscillations, their stability conditions and their representation in longitudinal phase space. Then it explains the concept of longitudinal phase space matching and its importance when you transfer the beam from one accelerator to another. Finally, it presents the Hamiltonian for the longitudinal motion.

      Depending on the application people use time-domain or frequency domain signals in order to measure or describe processes. First we will look at the definition of these terms, produce some mathematical background and then apply the tools to measurements made in the accelerator domain. We will first look at signals produced by a single bunch passing once through a detector (transfer line, linac), then periodic single bunch passages (circular accelerator) and at the end multi-bunch passages in a circular accelerator. The bunches themselves are considered rigid

      Emittance Measurements 1h

      Transverse emittance is one of the central figures of merit for charged-particle beams because it connects the microscopic phase-space distribution to macroscopic accelerator performance. This report introduces the trace-space description of emittance, relates it to the Courant-Snyder formalism and the beam matrix, and then follows the experimental logic behind common diagnostics. Emphasis is placed on how profile measurements, masks, drifts, quadrupole scans, and transverse deflecting structures convert otherwise inaccessible angular or slice information into measurable beam sizes.

      This introduction on beam position monitors (BPM) gives a quick overview on BPM systems and then dives into the individual parts. The focus is on the signal detection and normalization using BPM pickups, which couple to the electromagnetic (EM) field of a bunched beam. We cover the most popular BPM pickup types, like broadband button, stripline and split-plane BPMs, as well as resonant cavity BPMs. A note on the beam position measurement of low-beta beams and on the detection of higher order moments is also given. Finally, a few core aspects on BPM signal processing techniques are presented.

      Intensity Measurements 1h

      Analog-to-digital conversion is a crucial part of nearly all beam instrumentation systems. Ideally, in a well-engineered system, the used analog to digital converter (ADC) should not be the factor that limits overall performance. However, despite continuous advancements in ADC technology, this ideal is often not possible and the choice of ADC significantly influences or even restricts the final system performance. Consequently, it is essential to estimate the requirements for analog-to-digital conversion at an early stage of system design and determine if an adequate ADC exists to meet the system specification. For beam instrumentation systems demanding both high temporal and amplitude resolution, available converters often cannot meet the necessary specifications without specialised analog signal processing prior to digitisation. In such cases the ADC requirements may even determine the entire system architecture. This lecture aims to assist designers of beam instrumentation systems in the often iterative process of selecting an adequate ADC, offering an optimal trade-off between system performance, complexity and cost. As analog to digital conversion is extensively covered in existing literature, this lecture focusses primarily on aspects related to beam instrumentation systems.

      Analog Digital Conversion 1h

      Intensity is probably the most fundamental quantity characterising an accelerator beam, and its measurements are crucial for the efficient operation as well as optimisation of any accelerator. The importance of intensity measurement systems escalates for beams carrying energies capable of destroying accelerator components if deposited in an uncontrolled manner. In such cases, the systems provide critical signals to automatic protection systems, and, by consequence, the reliability and minimal signal latency take precedence over standard measurement precision and accuracy. In special cases, the significance of beam intensity extends beyond the accelerator itself, and its exact values are critical for conducting physics experiments or delivering medical treatments. Over the years many beam intensity measurement techniques have been developed and successfully applied in accelerators to cover vast needs in terms of temporal resolution and intensity ranges. This one-hour lecture focuses on non-invasive electromagnetic intensity sensors allowing temporal resolutions ranging from DC to the nanosecond range. Faster optical techniques are covered in a separate lecture on longitudinal profile measurements.

      Monochromatic X-ray beam position monitors are critical for maintaining stable beam delivery along synchrotron beamlines. This lecture reviews transmissive XBPM technologies used downstream of the monochromator. Single crystal CVD diamond XBPMs provide high transmission, radiation hardness, fast response, and nanometre-scale resolution, but are limited by small active areas and fragile surface electrodes. Silicon carbide XBPMs offer comparable performance with significantly larger active areas, extending applicability to larger beam sizes. A graphitic-wire pixel detector developed at Diamond Light Source is also presented, enabling simultaneous beam position and profile measurements within a robust, fully transmissive architecture. The role of XBPMs in beamline feedback systems is discussed, highlighting their use in correcting beam motion arising from environmental and operational disturbances. These developments reflect the ongoing evolution of XBPM technologies to meet the demands of modern synchrotron facilities.

      The uncontrolled release of even a small fraction of the energy stored in the beams or magnet systems of a high-energy particle accelerator can cause severe damage to accelerator and detector components, potentially resulting in significant downtime. This necessitates a careful evaluation of possible failure scenarios and their mitigation through passive and active protection systems.
      This lecture will introduce the field of machine protection, providing an overview of the sophisticated machine protection system implemented in the LHC and illustrating failure cases from existing and future accelerators. It will also present insights from material damage tests performed at CERN to assess the consequences of failures beyond design.

      This lecture introduces the theoretical foundations of Schottky spectra as a non-invasive diagnostic method in circular accelerators. Starting from the statistical origin of Schottky noise in coasting and bunched beams, we derive how uncorrelated particle motion gives rise to characteristic spectral structures in the vicinity of revolution harmonics. The formation of synchrotron and betatron sidebands is explained, together with their dependence on fundamental beam parameters such as tune, momentum spread, and chromaticity. Emphasis is placed on the linear, single-particle description of beam dynamics and on how the measured frequency-domain signatures emerge directly from microscopic fluctuations. The lecture aims to provide a clear, self-contained theoretical framework for interpreting Schottky spectra in practical accelerator diagnostics.

      Precise Timing and Synchronization I 1h

      This lecture examines synchronization systems in modern accelerators, focusing on radio-frequency (RF) methods and their
      role in achieving sub-10-fs beam arrival time precision. After motivating the need for high-precision timing, we analyze the
      short- and long-term stability of RF synchronization systems, including their fundamental limitations in ultra-low-jitter regimes.
      The discussion covers key microwave components—such as phase-locked loops (PLLs), mixers, oscillators, cables, amplifiers,
      and detectors—with emphasis on their phase-noise behavior, modeling techniques, and measurement techniques. We then
      explore global implementation strategies for synchronizing accelerator subsystems, highlighting approaches like un-stabilized
      chain systems, optical resynchronization, passive temperature stabilization, interferometer-based methods, and unidirectional
      transmission. Particular attention is given to subsystems critical for sub-10-fs jitter performance, including low-level RF (LLRF)
      systems and RF oscillator architectures, whose instabilities dominate timing errors in cutting-edge facilities.

      practices to minimize distortions—challenges shared by both RF and optical systems when interfaced with high-performance
      readout electronics. The core components of pulsed optical distribution systems are discussed, including mode-locked lasers,

      Schottky Diagnostics II 1h

      As was demonstrated in the “Schottky Diagnostics I” lecture, this non-invasive detection method provides valuable information about synchrotron beam parameters such as tune, momentum spread and chromaticity. Since the analysis is based on the observation of microscopic particle fluctuations in coasting and bunched beams, great attention must be paid to the proper design of the detector and signal path. After a brief recap of the first part of the lecture, a broad overview of the various implementations and system designs will be given. The lecture will also present examples of Schottky measurements performed on various ion synchrotrons.
