Polish scientific society, for many decades, has been actively participating in research exploring synchrotrons and free-electron lasers facilities worldwide. Recently, the construction of the SOLARIS National Synchrotron Radiation Centre in Kraków was completed. SOLARIS belongs to the family of low energy synchrotrons with a 1.5 GeV storage ring and presently offers several beamlines for user operation. In parallel, the PolFEL free-electron laser facility at National Centre for Nuclear Research in Warsaw is under construction, and the facility will deliver the first photon beams in 2023. We will present areas of accelerator-based photon research where the Polish scientific community is active and discuss trends and research routes of interest to be implemented at SOLARIS and PolFEL facilities.

PolFEL - Polish Free Electron Laser will be driven by a continuous wave superconducting accelerator consisting of low emittance superconducting RF electron gun, four accelerating cryomodules, bunch compressors, beam optics components and diagnostic elements. The accelerator will split in three branches leading to undulators producing VUV, IR and THz radiation, respectively. Two accelerating cryomodules will be installed before a dogleg directing electron bunches towards IR and THz branches. Additional two cryomodules will be placed in the VUV branch accelerating electron bunches up to 185 MeV at 50 kHz repetition rate. Moreover, the electron beam after passing the VUV undulator will be directed to the Inverse Compton Scattering process for high energy photons experiments in a dedicated station. In order to measure and optimise the electron beam parameters along the entire accelerator the main diagnostics components like BPMs, charge monitors, YAG screens, coherent diffraction radiation (CDR) monitors and beam loss monitors are foreseen. Within this presentation the concept of the electron beam diagnostics will be discussed.

The FEBE beamline at the CLARA facility will combine a 250 MeV FEL quality electron beam with a 100 TW class laser. One area of research FEBE will support is novel acceleration schemes; both structure and plasma based. There are stringent diagnostic requirements for measuring the input electron beam and challenges in characterisation of the accelerated beams produced by these novel schemes. Several of these challenges include measurement of: micrometer scale transverse profiles, 10 fs scale bunch lengths, single shot emittance, broadband energy spectra at high resolution, and laser-electron time of arrival jitter. Furthermore, novel shot-by-shot non-invasive diagnostics are required for machine learning driven optimisation and feedback systems. This paper presents an overview of R&D activities in support of developing a 6D diagnostics suite to meet these challenges.

Funding:*This work supported by the U.S. Department of Energy Office of Science under Cooperative Agreement DE-SC0000661, the State of Michigan and Michigan State University. The Facility for Rare Isotope Beams has commenced operation for production of rare isotope beams. A large suite of beam diagnostics and instrumentation have been developed and commissioned for the FRIB linac, target, and fragment separator systems. This talk will present the status of diagnostic systems to support current beam commissioning activities and experimental support for rare isotope production. We will review the performance of specific diagnostic systems used for position, intensity, beam distribution, and beam loss measurements. The initial performance of target and fragment separator diagnostics will be discussed. Aspects of the machine protection system and global timing system to support flexible, high power operation are presented. Finally, development of novel or enhanced techniques in signal processing will be introduced as means to improve overall system performance for various classes of diagnostics.

The European Spallation Source (ESS), currently under construction and initial commissioning in Lund, Sweden, will be the brightest spallation neutron source in the world, when its driving proton linac achieves the design power of 5 MW at 2 GeV. Such a high power requires production, efficient acceleration, and almost no-loss transport of a high current beam, thus making design and beam commissioning of this machine challenging. During the the commissioning time in 2022 a campaign for a full characterisation of the ESS Medium Beta Transport session (MEBT) was carried out. Both transverse optics and longitudinal parameters were measured and compared to simulation, amongst them: buncher cavity tunning, trasnverse emittance and initial twiss parameters. In this paper we present the results and future plans.

This poster will give an overview of the diagnostics development for SLS 2.0. Details on the beam size monitors in the storage ring, the screen monitors for the booster to ring transfer line, and beam loss monitors for the linac and storage ring will be presented. Test results carried out at the SLS will also be presented. BPMs and feedback systems are not covered in this contribution.

As part of the global refurbishment of the injector at BESSY II, a new optical beamline has been installed in the booster. This paper covers the conceptual design: incorporating the beamline into an operational facility without downtime, the simulation and expectations of the optical transport line, mechanical installation and commissioning with beam. These first results with the present beam delivery system have already achieved source point imaging and bunch length measurements using a fast diode. With the additional PETRA cavity installed for this booster upgrade and connection to acquire RF power in the 2022 summer shutdown planned, the bunch length diagnostics are critical. The beamline will also undergo a final mechanical upgrade and then see the installation of a streak camera.

The High Energy Storage Ring (HESR), within the FAIR project, will according to current planning provide anti-proton beams for PANDA and heavy ion beams for a.o. SPARC. With the beam instrumentation devices envisaged in larger quantities, e.g. BPM and BLM, testing is well underway. Other beam instrumentation instruments like Viewer are in late production stage, Scraper is being tested and for the IPM the 1st of series production has started. An overview of the status of the work package beam instrumentation will be presented as well as test bench results of already produced instruments.

The passage of a high-intensity particle beam inside accelerator components generates heating, potentially leading to degradation of the accelerator performance or damage to the component itself. It is therefore essential to monitor such beam-induced heating in accelerators. This paper showcases the capabilities of iPipe, which is a set of Fiber Bragg Grating sensors stuck on the inner beam pipe of the Compact Muon Solenoid (CMS) experiment installed in the CERN Large Hadron Collider (LHC). In this study, the wavelength shift, linked directly to the temperature shift, is measured and is compared with the computed dissipated power for a set of LHC fills. Electromagnetic and thermal simulations were also coupled to predict the beam-induced temperature increase along the beam pipe. These results further validate the sensing system and the methods used to design accelerator components to mitigate beam-induced heating.

In late 2021 through mid 2022, the first protons were accelerated and transported through the European Spallation Source (ESS) Radio Frequency Quadrupole and Medium Energy Transport line at 3.6 MeV, and finally through the first Drift Tube Linac tank at 21 MeV. To enable these achievements, the following beam instrumentation systems were deployed: Ion Source power supply monitors, beam chopping systems, Faraday Cups, Beam Current Monitors (BCM) and Beam Position Monitors (BPM) that also measured phase. Additional systems were deployed for dedicated studies, including Wire Scanners, a slit and grid Emittance Measurement Unit, neutron Beam Loss Monitors and fast BCM and BPM systems. The instrumentation deployment is the culmination of efforts by a partnership of the ESS beam diagnostics section, multiple ESS groups and institutes across the globe. This paper summarizes the beam tests that characterized the performance of the instrumentation systems and verified the achievement of commissioning goals.
