Targeted α-therapy with α-particle-emitting isotopes such as 225Ac, 223Ra, 213Bi, 212Pb, has demonstrated a successful clinic trial effect. However, the major bottleneck for conducting translational research and future extensive clinical treatments is the limited availability of those α-emitting isotopes. Meanwhile, radioactive ion beam physics research, material irradiation and nuclear...
I will present an overview of the current status of IsoDAR Cyclotron research and development, as well as the associated physics program.
Originally conceived to meet the requirements of the IsoDAR (Isotope Decay-At-Rest) neutrino experiment, the modular design of the HCHC (High-Current H₂⁺ Cyclotron) family enables the fabrication of cost-effective and compact cyclotrons covering an energy...
ome of the new cyclotron projects currently under study or construction address new challenges. In particular, the START project of the company TRANSMUTEX to drive a subcritical reactor with a 4 MW proton beam, the 6 MW CYCIAE-2000 project, the IsoDar cyclotron of MIT, the new 230 MeV superconducting cyclotron for proton therapy and flash therapy in Dubna, and the upgrading of the Catania...
An accelerator system employing RF cavities requires the use of a stable RF source, and some require multiple frequencies, either for acceleration or for bunching. These frequencies must be synchronized in phase in order to work properly. These are usually derived from a single low phase noise master reference frequency source. A fixed frequency oscillator or a variable frequency oscillator...
A new injection beamline for the 500 MeV cyclotron has been designed, constructed, and commissioned. Approximately 40 meters of electrostatic transport now replace the previous injection system, extending from the H⁻ ion source to the vertical injection section. The upgrade also includes the integration of a second H⁻ ion source, connected through additional electrostatic beam transport, to...
The upgrade of the Superconducting Cyclotron at INFN Laboratori Nazionali del Sud in Catania is aimed at improving its performance in terms of intensity of light ions, as well as in terms of reliability. The project was financed in 2019 by the Italian Ministery of University and Research. The Cyclotron was kept operative until the end of 2020, then in 2021 it was dismantled, so as to proceed...
The upgrade project of the RCNP K140 AVF cyclotron was initiated in 2019 to provide intense light-ion beams for the production of short-lived radioisotopes and high-quality, high-intensity beams for precision nuclear physics experiments. Except for the main coil, pole pieces, and yoke of the cyclotron magnet, most components were replaced with newly fabricated systems. In particular, the...
Although the cyclotron accelerators at HIRFL, namely the Sector-Focused Cyclotron (SFC) and the Separated Sector Cyclotron (SSC), are over sixty years old, beam commissioning continues to run successfully. The SFC, installed in 1962, can accelerate heavy ions to 17 MeV per nucleon or protons to 37 MeV, with an average current of 10 µA. The SSC (Sector-Separated Cyclotron), commissioned in...
The cyclotron, which has been around for over 80 years, experienced a period of vigorous development in the last ten years due to urgent needs in multiple application fields, specially for ultra-compact, ultra-lightweight, and high-power cyclotrons.
Since 2013, a low-temperature 230MeV superconducting cyclotron CYCIAE-230 has been developed and successfully obtained the first beam at 231MeV...
We present the magnet design of an adjustable-field isochronous permanent magnet cyclotron concept, capable of accelerating protons to 18 MeV. Within the cyclotron, the permanent magnet is distributed about the cyclotron return yoke above and below the midplane in rotatable cones. With an outer radius of 1.36 m and height of 1.22 m, the design can replicate the field strength (up to 2.3 T...
A series of upgrades were implemented at the AECR ion source at UMCG-PARTREC to improve ion beam performance. The focus was on increasing beam intensity, enhancing long-term stability, optimizing ion species control in cocktail beams, and identifying optimal RF injection frequencies for plasma heating. A key enhancement was the installation of an Einzel lens. This increased the transmission...
We propose a new class of compact superconducting cyclotrons based on the stripping of H3+ ions. In this method, H3+ ions are accelerated and pass through a thin carbon foil, where the electrons are removed to produce three protons per ion. Compact cyclotrons require high magnetic fields, which makes H- acceleration impractical; H3+ ions, however, can possibly tolerate much higher fields and...
A superconducting cyclotron, the CYCIAE230, has been developed by CIAE of CNNC for proton therapy applications over the past few years. The beam commissioning of this machine was completed previously, in 2023. A series of improvements were carried out in the early part of this year to increase the stability and beam intensity of the cyclotron for potential FLASH usage. It includes optimizing...
This manuscript examines the non-linear interaction between the negative energy beam cyclotron mode and high-frequency whistler waves. The negative energy beam mode is supported in the vicinity of the beam gyro-frequency harmonics by a gyrating ion beam with
ring shaped velocity distribution. Using a gyrating ion beam, we have examined how dust charge variations affect the parametric...
Alpha particle accelerators hold significant potential for applications in the production of medical radioisotopes, particularly demonstrating unique advantages in obtaining At-211 medical radioisotope, which is difficult to produce via traditional neutron reactions, such as reactor neutron irradiation. In this paper, a high-frequency resonant cavity operating at 36.8 MHz was designed for a 30...
To address the demands for extensive customization, high measurement throughput, and stringent control accuracy in cyclotron magnetic-field measurement and control, this paper presents a general-purpose, parameterized system. The hardware platform is centered on a Beckhoff PLC, integrating I/O, encoder, and serial-communication modules, and supporting both EtherCAT-based stepper and servo...
