93. Post-Mortem Insights into the SNS RFQ: Implication and Paths Forward for high beam power operation

Haitao Ren (Oak Ridge National Laboratory)

19/08/2026, 08:30

MC4.A07: Room temperature RF

Invited Talk (Invitation Only)

The first Radio-Frequency Quadrupole (RFQ01) at the Spallation Neutron Source (SNS) operated in both the main accelerator and the Beam Test Facility for a combined period of approximately 20 years. Over this time, the performance of RFQ01 declined significantly, with beam transmission decreasing from about 90% to 70% or less. RFQ01 is currently undergoing a comprehensive post-mortem analysis....

39. Overview and current status of the IFMIF-DONES accelerator systems

Dr Ivan Podadera (Consorcio IFMIF-DONES España)

MC3.A02: Ion linac projects

Invited Talk (Invitation Only)

Overview and current status of the IFMIF-DONES accelerator systems is presented.

94. A SURVEY OF THE GLOBAL SCIENTIFIC KLYSTRON MARKET AND ITS FUTURE

John Moss (Oak Ridge National Laboratory)

19/08/2026, 09:10

MC4.A06: RF power sources and power couplers

Invited Talk (Invitation Only)

The continued high-quality scientific output of many research facilities depends directly on their reliable operation and, in taking a wider view, a market that can provide a stable supply. In the late 2010s and early 2020s, market irregularities were amplified in large part because of the COVID-19 pandemic and the disruption it caused in resource availability. Though COVID-19 has been...

438. Status of the HIAF Linacs

Weilong Chen (Institute of Modern Physics, Chinese Academy of Sciences)

19/08/2026, 09:30

MC3.A02: Ion linac projects

Invited Talk (Invitation Only)

IMP is constructing two major projects near Huizhou. Both involve the installation of superconducting hadron linacs with equipment that has been developed by IMP over the last decade or more. The presentation should summarize progress on the two projects.

89. TRANSFORMING THE BNL 200 MeV H⁻ LINAC: 10³ LOWER LOSSES, 2× HIGH-CURRENT TRANSMISSION, AND 2× LOWER EMITTANCE

Deepak Raparia (Brookhaven National Laboratory)

MC3.A03: Other proton/ion

Invited Talk (Invitation Only)

Abstract
The Brookhaven National Laboratory (BNL) 200 MeV Drift Tube Linac (DTL) operates at 6.67 Hz, delivering H⁻ beams for both the polarized proton program at RHIC and isotope production at BLIP. Over the past two decades, targeted upgrades—especially within the low-energy and medium-energy beam transport (LEBT and MEBT) sections—have dramatically enhanced linac performance. Beam...

90. High-Current Heavy-Ion Acceleration Above 100 mA in a Four-Rod RFQ

Masahiro Okamura (Brookhaven National Laboratory)

MC1.A03 Other beams

Invited Talk (Invitation Only)

We report on the achievement of a world-record peak beam current for heavy ions through the acceleration of fully stripped carbon ions (C⁶⁺) using a 100-MHz four-rod radio-frequency quadrupole (RFQ) accelerator combined with a Direct Plasma Injection Scheme (DPIS) driven by a laser ion source.
A peak beam current of 105 mA was successfully accelerated to an output energy of 300 keV/u. The...

42. 25 years of FEL operation at FLASH (DESY)

Katja Honkavaara (Deutsches Elektronen-Synchrotron DESY)

MC2.A04: FELs

Invited Talk (Invitation Only)

First SASE lasing at DESY's FLASH Free-electron laser (FEL) - that time called as TESLA Test Facility FEL - was in February 2000. It was the first FEL worldwide producing SASE radiation at VUV wavelengths. Since then, over more than two decades, FLASH has provided high peak and average brilliance XUV and soft X-ray FEL radiation for photon science experiments.

In order to operate FLASH as...
