61. Printed H - Cavity Options Above 100 MeV/u

Ulrich Ratzinger (Goethe - Universität Frankfurt)

20/10/2026, 10:45

Beam dynamics and cavity design studies have been performed to investigate H - type structures in the frequency range from 500 to 1000 MHz. Comparisons in RF efficiency and structure complexity with established DTL's in that velocity range are shown.

53. Additive Manufacturing of Accelerator Structures — Opportunities and Challenges from an Industrial Perspective

Peter vom Stein (RI Research Instruments GmbH)

The manufacturing of normal-conducting accelerator structures relies on a long supply and manufacturing chain, in which time and cost drivers are sometimes hidden within subsystems. Additive manufacturing offers the opportunity to drastically simplify manufacturing processes and thus generate economic value. However, this requires a fundamental reevaluation of existing designs rather than...

54. Application of Additive Manufacturing in Beam Diagnostics and Radiation Shielding

Leonie Bauer (Goethe University Frankfurt, Institute for Applied Physics)

20/10/2026, 11:35

Additive manufacturing provides a fast, cost-effective, and flexible method for developing customized camera mounts that can be precisely adapted to their designated positions, both inside and outside of Linac cavities. Besides beam characterization, CMOS cameras at our institute are also applied to acquire multipacting and cavity glowing effects during conditioning. In this case, due to the...

50. Rapid design-print-test cycles for additively manufactured accelerator cavities

Niv Levy (Tachyon Industrial)

20/10/2026, 13:00

Linear accelerator fabrication has remained largely unchanged for decades: components are precision-machined, assembled, and tuned through many iterative cycles. This model is well suited to scientific facilities, but less so to industrial applications, where rapid iteration, customization, and cost control are essential.

Additively manufactured accelerator structures may offer a better fit...

57. 3D-Printed 4-Rod RFQ Including Gyroid Cooling Structures

Julius-Stephan Storch (Goethe Universität, Frankfurt)

20/10/2026, 13:25

In high-duty-cycle and CW operation, 4-rod RFQs are limited mainly by heat removal from stems and the tuning plates. Local heating causes deformation, detuning and a degraded field distribution. Conventionally manufactured cooling channels are limited in their form and position by the manufacturing process.

This talk presents the development of a 4-rod RFQ prototype made by laser powder bed...

62. Compact Ion Accelerators at High Frequencies – Use of Additive Manufacturing Processes

Benjamin Dedic (Goethe Universität Frankfurt)

20/10/2026, 13:50

Metal additive manufacturing offers new opportunities for compact, normal-conducting linear accelerator components. This work investigates additively manufactured IH-type drift-tube structures, focusing on fabrication tolerances, post-processing, RF performance, and thermal management. Electromagnetic simulations and low-level RF measurements show that small geometric deviations can shifts in...

45. Challenges and Opportunities for 3D Printed RF Gun Cavities

Benno Zeitler (DESY)

20/10/2026, 14:45

High-gradient RF-photo-injectors offer outstanding electron-beam quality and properties, and are therefore utilized as drivers for X-ray free-electron lasers (XFELs), ultra-fast electron diffraction (UED), and other applications requiring short bunches with low emittance. DESY, with its sites in Hamburg and Zeuthen, has several decades of experience in developing and operating these particle...

56. Development of an Additively Manufactured 1.3 GHz Cavity for PLEPS

Vitus Michael Schuster (Universität der Bundeswehr München (LRT2))

20/10/2026, 15:10

A compact 1.3 GHz linear particle accelerator (linac) is currently under development to extend the range of applications of the pulsed low-energy positron system (PLEPS) located at the Forschungs-Neutronenquelle Heinz Maier-Leibnitz (FRM II). The linac is based on a side-coupled radio-frequency (RF) cavity (SCC) geometry to reduce footprint and power consumption. However, conventional...

65. Additive Manufacturing and Conjugate Heat Transfer Analysis of a Gyroid Cooling Plate

Ramy Cherif (G.S.I)

20/10/2026, 15:35

This presentation explores the design, additive manufacturing and thermal performance of a CuCr1Zr cooling plate with an internal gyroid structure for electronic components in particle accelerator systems. The manufacturing process combines laser powder bed fusion with subsequent heat treatment and machining of functional surfaces. Steady-state and transient conjugate heat transfer (CHT)...
