MeV class accelerators were introduced in Canada in 1947 with the commissioning of the world’s first microtron producing 4.6 MeV electrons. Through the early years a variety of machines were realized driven by, primarily, sub-atomic physics science pursuits. Two main centres of accelerator activity have emerged in Canada; at TRIUMF in Vancouver and CLS in Saskatoon. A number of smaller accelerators dot the country for medical and other applications. Industrial companies have formed to supply accelerators or accelerator sub-systems. The talk will give a brief historical overview of accelerator development in Canada, describe the present status and provide an overview of future initiatives.

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 i.a. the SPARC experiment. Manufacturing for most of the envisaged beam instrumentation devices in vacuum is completed and testing is well underway. The overall status update of the beam instrumentation devices is presented, with a focus on the test-bench results of the BPMs. In addition, the planned future timeline of the HESR beam instrumentation is briefly reported.

Spatial fractionated radiotherapy using protons, so-called proton minibeam radiotherapy (pMBT) was developed for better sparing of normal tissue in the entrance channel of radiation. Progressing towards clinical use, pMBT should overcome current technical and biomedical limitations. This work discusses a preclinical pMBT facility, currently built at the 68.5MeV cyclotron at the Helmholtz Zentrum Berlin. The goal is to irradiate small animals using focused pMBT with a σ of 50µm, a high peak-to-valley dose ratio at center-to-center distance as small as 1mm and beam current of 1nA. A first degrader defines the maximum energy of the beam. Dipole magnets and quadrupole triplets transport the beam to the treatment room while multiple slits properly form the transverse beam profiles. A high magnetic field gradient triplet lens forms the minibeams in front of the target station and, scanning magnets are used for a raster scan at the target. An additional degrader, positioned close before the focusing spot and the target, further reduces the energy, forming a spread-out Bragg peak. A small animal radiation research platform will be used for imaging and positioning of the target.

HEPS is a fourth generation light source which has horizontal emittance around 34pm.rad to gain the high brilliance photon beam, this ultra-low emittance brings many engineering challenges for beam instrumentation. The resolution of the beam position measurement and the beam size measurement is need to reach sub-micro meter. The large current and multi-bunches need bunch by bunch feedback system to cure instabilities. This paper will present an overview of beam instrumentation

This paper presents a natural extension of prior theoretical investigations regarding the utilization of coherent diffraction radiation for assessing longitudinal characteristics of electron beams at Solaris. The study focuses on the measurement results obtained at the linac injector of the Solaris synchrotron and their analysis through a theoretical model. The findings are compared with previous estimates of the electron beam longitudinal profile. This paper contributes to the future diagnostics at the first Polish free electron laser (PolFEL) project, where it will be used for the optimization of particle accelerator performance.
SOLARIS linac currently operates at 540 MeV and is used as an injector to the storage ring, where after the accumulation the energy is ramped up to 1.5 GeV via two active RF cavities. Top-up injection would be of extreme benefits for user operation, therefore a new 1.5 GeV linac is being designed. The idea is to replace the current machine without infrastructural interventions in terms of tunnel expansion. Performed studies demonstrate that the best solution is provided by a Hybrid S-band/C-band LINAC. One of the main goals is to achieve bunch compression below the picosecond level and low-emittance beams for a future short-pulse facility or a Free Electron Laser. Within this presentation the results of performed simulations will be presented together with the concept of different diagnostics as BPMs, current transformers, YAG screens, coherent diffraction radiation monitor distribution.

The CERN accelerator complex stands out as an unique scientific tool, distinguished by its scale and remarkable diversity. Its capacity to explore a vast range of beam parameters is truly unparalleled, spanning from the minute energies of around a few keV and microampere antiproton beams, decelerated within the CERN antimatter factory, to the 6.8 TeV high-intensity proton beams that race through the Large Hadron Collider (LHC). The Super Proton Synchrotron (SPS) ring plays also a crucial role by slowly extracting protons at 400 GeV. These proton currents are then directed toward various targets, generating all sorts of secondary particle beams. These beams, in turn, become the foundation of a diverse fixed-target research program, enabling scientific exploration across a wide spectrum. Moreover, as CERN looks ahead to future studies involving electron-positron colliders, the development of cutting-edge diagnostics for low emittance, short electron pulses is also underway. This contribution serves as a snapshot, shedding light on the main R&D initiatives currently underway at CERN in the field of beam instrumentation.

Funding:This work was done under the auspices of CHART (chart.ch) This paper is an overview of a diagnostics setup for highly spread e⁺e⁻ beams, to be installed at the PSI Positron Production (P3 or P-cubed) experiment. To be hosted at the SwissFEL facility (PSI, Switzerland) in 2026, P3 is e+ source demonstrator designed to generate, capture, separate and detect nano-Coulombs of secondary e+ and e- bunches, in spite of their extreme tranverse emittance and energy spread. The experiment will employ an arrangement of broadband pick-ups (BBPs) to detect simultaneously the time structure of secondary e⁺e⁻ bunches. A spectrometer will follow the BBPs and deflect the e+ and e- onto two unconventional faraday cups that will measure their charge. In addition, the energy spectrum of e+ and e- distribution will be reconstructed through scintillating fibers.

Funding:Los Alamos National Lab LDRD The Accelerator Operations and Technology division is upgrading the control system for a 33-ton shield door that will be used when the Cathodes and RF Interactions in Extremes (CARIE) accelerator begins operations. The door was installed in the 1990¿s but safety standards such as ISO 13849-1 have since emerged which provide safety requirements and guidance on the principles for the design and integration of safety-related parts of a control system. Applying this standard, a safety controller, safety relays and a light curtain barrier have been added to eliminate injury and exposure of personnel to potential hazards during door operations.

The SuperKEKB electron-positron collider, which started the commissioning in February 2016, is a luminosity frontier machine for the search for new physics. In this presentation, we review the main challenges we face for the high-energy and low-emittance beam at SuperKEKB, fast and low-noise beam-orbit feedback system, X-ray beam-profile monitors for measurements for the beam size of ¿10 um, novel diamond mirrors with extremely high thermal conductivity for extracting synchrotron radiation, and various type’s beam loss diagnostics for the identification or possibly early detection of sudden beam losses. This presentation includes future directions of the R&D–-X-ray interferometry for micron-level beam size measurements and fast optics measurements with the gated turn-by-turn BPMs–-towards next-generation light source facilities and high-energy colliders.

Funding:Turkish Energy, Nuclear and Minerals Research Agency A 30 MeV cyclotron is operated at TENMAK-NUKEN for producing medical radioisotopes with three beamlines and a fourth beamline is dedicated for research purposes. The minimum energy of extracted proton beam from cyclotron is 15 MeV. There is no facility in Türkiye for applying ion beam analysis techniques (IBA) currently. These techniques generally require 1-5 MeV proton beam energy. An energy degrader system was designed and installed on the R&D beamline for this purpose. The degrader system is capable of decreasing the energy down to 1 MeV with pA to uA current levels. A high vacuum irradiation chamber is designed and installed at the end of the beamline. The chamber has ports to install several types of detectors for different IBA techniques. This work includes the description of the setup and preliminary PIXE measurements.
