The Facility for Rare Isotope Beams (FRIB) driver linac will deliver all stable heavy ion beams with energy more than 200 MeV/u and beam power on target up to 400 kW. Since FRIB is the first SRF linac for high power heavy ion beams, design and integration of the accelerator components are important and there are many challenges. Several issues on design and integration of the linacare introduce...

We demonstrate that, despite differences in their nature, many energy beam controlled-depth machining processes (for example, waterjet, pulsed laser, focused ion beam) can be modeled using the same mathematical framework-a partial differential evolution equation that requires only simple calibrations to capture the physics of each process. The inverse problem can be solved efficiently through t...

Effects of the magnetic-field configuration on electrostatic ion acceleration in a magnetically expanding plasma source are experimentally investigated, where an expanding plasma machine with two solenoid coils is manufactured. The field configurations can be changed by adjusting the solenoid currents. The 13.56 MHz radiofrequency power for plasma production and the argon gas pressure are maint...

Background: In radiation therapy with ion beams, lateral distributions of absorbed dose in the tissue are important. Heavy ion therapy, such as carbon-ion therapy, is a novel technique of high-precision external radiotherapy which has advantages over proton therapy in terms of dose locality and biological effectiveness.Methods: In this study, we used Monte Carlo method-based Geant4 toolkit to s...

Introduction: Very low, Low and Medium X-ray machines are used extensively for Superficial Radiation Therapy mostly used for Basal Cell, Squamous Cell Carcinoma, and Melanoma skin cancers. In most of cases, Superficial X-ray Therapy (SXRT) is preferred to Electron beams generated using a linear accelerator. SXRT tube characteristics may vary with the use of the machine for a lo...

Introduction: Intraoperative radiotherapy is a radiotherapy technique in which a high single fraction of radiation dose is delivered to the patient after surgery and Concurrent with anesthesia time. The most frequent method for IORT implementation is Intraoperative electron radiotherapy (IOERT), in which, some dedicated and high dose per pulse electron accelerators are employe...

For destructive beam intensity measurements, electrostatic Faraday cups will be incorporated into the Ultra-low energy Storage Ring (USR) and its transfer lines at the Facility for Low-energy Antiproton and Ion Research (FLAIR). This multi-purpose machine will offer both slow and fast extracted beams resulting in a wide range of intensities and varying time structure of the beam. In this contri...

Introduction To prepare the acceleration of highest intensities of intermediate charge state heavy ion beams for the FAIR project, several technical projects have been summarized in the SIS18 upgrade program. The various technical measures of this program are continuously accompanied and verified by machine experiments. Major goal is the reduction of ionization beam loss. The strong dependence ...

For heavy-ion synchrotrons an efficient multi-turn injection (MTI) from the injector linac is crucial in order to reach the specified currents using the available machine acceptance. The beam loss during the MTI must not exceed the limits determined by machine protection and vacuum requirements. Especially for low energy and intermediate charge state ions, the beam loss can cause a degradation ...

A detailed understanding and monitoring of potential beam loss mechanisms is crucial for every particle accelerator. The main motivation in low energy facilities, such as the Ultra-low energy Storage Ring (USR) at the future Facility of Low energy Antiproton and Ion Research (FLAIR), comes from the very low number of particles available which in such machine ought to be conserved. In high energ...
