MC1: SRF Facilities

Invited Oral Presentation

The RIKEN superconducting heavy-ion linac, so-called SRILAC, has been successfully operating for almost five years, and continuously deliver a heavy ion beam for a super-heavy-element synthesis experiment by fixing minor and major hardware troubles. The effects of a broken coupler in the early days and four years of operation have resulted in increased X-ray emission levels in several...

27. Crystallinity in niobium oxides: a pathway for mitigation of two-level system defects in niobium 3D resonator for quantum applications (MOA02)

MC2: Fundamental SRF research and development

Invited Oral Presentation

Materials imperfections in Nb-based superconducting quantum circuits—in particular, two-level-system (TLS) defects—are a major source of decoherence, ultimately limiting the performance of quantum computation and sensing. Thus, identifying and understanding the microscopic origin of possible TLS defects in these devices will help developing strategies to eliminate them and is key to...

85. EIC crab cavity RF systems (MOA03)

Subashini De Silva (Old Dominion University)

MC3: Cavities

Invited Oral Presentation

The Electron-Ion Collider (EIC) is being implemented at Brookhaven National Laboratory (BNL) in a special partnership with Thomas Jefferson National Accelerator Facility. EIC is designed to collide electrons and protons/Heavy Ions with energies of 5-18 GeV, 2.5 A in the Electron Storage Ring (ESR) and 41-275 GeV/u, 1 A in the Hadron Storage Ring (HSR). The interaction region with a crossing...

42. Specification, design, production and test schedule of cryomodule for SRF 5-year plan (MEXT-ATD) at KEK by global collaboration for ILC technology network (MOA04)

Yasuchika Yamamoto (High Energy Accelerator Research Organization)

MC4: SRF Technologies

Invited Oral Presentation

A five-year project (MEXT advanced Accelerator element Technology Development (MEXT-ATD)) funded by the Ministry of Education, Culture, Sports, Science and Technology (MEXT) began at KEK in FY2023. The goal is to manufacture, construct and test a cryomodule (CM) that satisfies the ILC (International Linear Collider Project) specifications and conduct cooling tests. The MEXT-ATD program is...

93. Recent advances in 3D SRF cavity-based quantum computing facility at the Fermilab SQMS Center (MOA05)

Alexander Romanenko (Fermi National Accelerator Laboratory)

MC5: SRF Applications

Invited Oral Presentation

This talk will describe the most recent advances and progress in building an SRF cavity-based quantum computing facility at the Fermilab SQMS center. Several technical challenges had been successfully overcome to preserve the highest quality factors of SRF cavities in the presence of the sapphire chip holding the transmon qubit inside the cavity. The record values of the attained multicell...
