Ryan Bodenstein (Thomas Jefferson National Accelerator Facility)20/08/2026, 15:00MC1.A01: Beam Dynamics, beam simulations, beam transportPoster Presentation
We present a method for detecting and characterizing anomalies in a nominally decoupled, recirculating linac accelerator, such as the Continuous Electron Beam Accelerator Facility (CEBAF). Proposed future accelerators of this type include PERLE and LHeC. The method computes the zero-lag cross-plane covariance from samples of beam position data, and analyzes its singular value decomposition...

The European Spallation Source (ESS) aims to be the world's brightest neutron source, designed to delivering 2 GeV protons at 5 MW to a rotating Tungsten target via a 600 m-long superconducting linear accelerator. At the present installation phase, with 82 of the total 146 cavities available in the superconducting linac, a beam of 800 MeV (2 MW) can be produced. During the first half of 2026,...

The Electron-Ion Collider at Brookhaven National Laboratory requires high-current, high-brightness electron beams for efficient ion beam cooling. We present the design and beam dynamics optimization of a normal-conducting electron linac for the Low-Energy Cooler (LEC), building on operational experience from the Low Energy RHIC Electron Cooler (LEReC) and extending performance toward the...

Extraction efficiency is a key parameter for oscillator FELs. To evaluate it in a single macro-pulse, both electron beam energy evolution with and without FEL lasing must be known. Previously, we developed a secondary electron emission monitor (SEEM) to measure the temporal energy evolution after the undulator with and without FEL lasing*. Since SEEM requires separate measurements with and...

To enhance the energy efficiency and cost-effectiveness of large-scale particle accelerator facilities, energy recovery has emerged as a key research direction. From the perspective of radio frequency (RF) power sources, this article reports on the latest research progress in this field at IHEP. First, the fundamental principles of energy recovery based on RF power sources are elaborated,...

469. Development of high-gradient booster linac for multi-GeV proton radiography at LANSCE (THOP006)Sergey Kurennoy (Los Alamos National Laboratory)20/08/2026, 15:25MC3.A04: Proton linac projectsPoster Presentation
Increasing energy of proton beam at the Los Alamos Neutron Science Center (LANSCE) from 800 MeV to 3-5 GeV will improve radiography resolution ten-fold. This energy boost can be achieved with a compact cost-effective linac based on normal conducting high-gradient (HG) RF accelerating structures operating at liquid nitrogen temperatures (cryo-cooled). Such an HG booster is feasible for proton...

Additive manufacturing (AM) offers new possibilities for the design and fabrication of radio-frequency quadrupoles (RFQs), particularly in enabling complex internal geometries that are difficult or impossible to realize with conventional machining. In this work, the application of AM to the production of 4-rod RFQ structures made from pure copper and copper alloys is investigated.
A key...

efficiency with the same priority as achieving higher performance. Some linac installations like those for Accelerator Driven Systems (ADS) are advertised as being powered by the nuclear energy they produce... -
Peter Gerhard (GSI Helmholtz Centre for Heavy Ion Research)20/08/2026, 15:40MC4.A05: Other technologyPoster Presentation
The efficiency of stripping heavy ions like uranium into a single charge state at 1.4 MeV/u using a gas target can be increased significantly by applying hydrogen instead of nitrogen, thereby narrowing the resulting charge state spectrum. However, pulsed injection into a dedicated interaction chamber will be required to reduce the load of the vacuum pumping system to an acceptable level. Such...

473. 4D transverse coupling measurements of an 18 MeV photo-injector electron beam at PITZ (THOP010)Christopher Richard (Deutsches Elektronen-Synchrotron DESY)20/08/2026, 15:45MC4.A01: Beam diagnosticsPoster Presentation
At the Photo-Injector Test facility at DESY in Zeuthen (PITZ), the horizontal and vertical phase spaces of electron beams are measured to characterize the performance of L-band photo-electron sources. These measurements are taken use a using the slit-screen method located 5.27 m downstream of the photo-cathode after acceleration to 18 MeV by a 14-cell booster cavity. The beamlet images from x...

Nb$_3$Sn is one of the most promising materials for next-generation superconducting radio-frequency (SRF) cavities, as it enables high-Q operation at 4 K. This feature opens the possibility of conduction-cooled SRF systems without liquid helium. At KEK, Nb$_3$Sn coating development based on the Sn vapor diffusion method has been in progress since 2019, with continuous improvements in cavity...
