54. Facility for Rare Isotope Beams: Never the Same Beam Twice

T. N. Ginter (Facility for Rare Isotope Beams)

5/28/24, 8:40 AM

Source terms, new accelerator facilities and related topics

Oral presentation (preferred)

The Facility for Rare Isotope Beams (FRIB) – a world-leading laboratory for providing exotic beams – is entering its third year of user operation. The facility produces rare-isotope beams through in-flight fragmentation of high-power beams of stable heavy-ion isotopes ranging from oxygen to uranium and at energies up to 200 MeV per nucleon. This year the facility will double its primary beam...

37. Modeling tritium production and release in high-energy proton accelerators

Dali Georgobiani (FNAL)

5/28/24, 9:00 AM

Source terms, new accelerator facilities and related topics

Oral presentation (preferred)

Tritium is a well-known byproduct of particle accelerator operations. To keep levels of tritium below regulatory limits, tritium production is actively monitored and managed at Fermilab.
We study tritium production in the targets, beamline components, and shielding elements of the Fermilab facilities such as NuMI, BNB, and MI-65. To facilitate the analysis, we construct a simple model and use...

84. Monte-Carlo simulations of the ESS accelerator radiation environment using kernel density estimation techniques

Douglas Di Julio (European Spallation Source ERIC)

5/28/24, 9:20 AM

Source terms, new accelerator facilities and related topics

Oral presentation (preferred)

The Spallation Physics Group at the European Spallation Source (ESS) maintains a detailed model of the ESS accelerator for Monte-Carlo simulations. This model can be used together with the codes PHITS, MCNP6, and FLUKA for calculations of prompt dose rates and nuclide inventories produced around the accelerator. This includes problems involving for example deep-penetration of neutrons through...

82. RP Commissioning of the LCLS-II linac at low power

Thomas Frosio (SLAC)

5/28/24, 9:40 AM

Source terms, new accelerator facilities and related topics

Oral presentation (preferred)

The LCLS-II at SLAC represents a significant upgrade over its predecessor, introducing advancements in X-ray laser technology to provide a deeper understanding of atomic structures. The commissioning of the linac includes a series of surveys that are performed at different steps while ramping up energy, power and parking beam at different locations of the beamline. This presentation details...

56. The European XFEL after 6 years of operation - a status report

Albrecht Leuschner (Deutsches Elektronen-Synchrotron (DESY))

5/28/24, 10:00 AM

Source terms, new accelerator facilities and related topics

Oral presentation (preferred)

An overview of the performance of the EuXFEL after more than 6 years of operation is given.
The second part deals with the challenges with regard to radiation protection.These arise mainly from the high average power of the electron beam of a maximum of 300 kW per main absorber and the high energy content of the X-ray pulses of up to 10 mJ.

31. The Beam Test Facility of the Laboratori Nazionali di Frascati

Bruno Buonomo (Istituto Nazionale di Fisica Nucleare), Clara Taruggi (Istituto Nazionale di Fisica Nucleare), Claudio Di Giulio (Istituto Nazionale di Fisica Nucleare), Domenico Di Giovenale (Istituto Nazionale di Fisica Nucleare), Eleonora Diociaiuti (Istituto Nazionale di Fisica Nucleare), Fabio Cardelli (Istituto Nazionale di Fisica Nucleare), Luca Gennaro Foggetta (Istituto Nazionale di Fisica Nucleare)

Source terms, new accelerator facilities and related topics

Oral presentation (preferred)

The Beam Test Facility (BTF) of the National Laboratories of Frascati provides external users with positron/electron primary and secondary beams in various configurations for detector calibration purposes.
The BTF beam is organized into bunches, with a repetition rate of up to 49 pulses per second from the DAΦNE LINAC facility. Each bunch offers impressive flexibility, accommodating a...

62. Monte Carlo Simulations for the Future TATTOOS Target Station at PSI

Dr Aleksandar Ivanov (Paul Scherrer Institute)

5/28/24, 11:10 AM

Medical and industrial accelerators

Oral presentation (preferred)

TATTOOS (Targeted Alpha Tumour Therapy and Other Oncological Solutions) is a proton irradiation target station to be built at PSI as part of the IMPACT project. The design goal of TATTOOS is to produce a wide range of radionuclides for diagnostics and therapeutics. Currently, UCx (Uranium Carbide) and Ta (Tantalum) targets are under investigation. Both the UCx and the Ta target will be...

60. Beam loss monitoring in NanoTerasu storage ring with active neutron dosimeter

Akihiro Takeuchi (National Institutes for Quantum Science and Technology)

5/28/24, 11:30 AM

Source terms, new accelerator facilities and related topics

Oral presentation (preferred)

A compact 3 GeV synchrotron light source (NanoTerasu) has been in operation at Tohoku University’s new Aobayama campus in Japan since April 2024. NanoTerasu provides both soft and hard x-rays from insertion devices installed in the 3 GeV storage ring [1,2]. At present 10 of the 28 beamlines designed are available; the remaining 18 beam lines will be installed in the future. The storage ring is...
