L2 Groups
Organization
The Higgs Factory Circular Collider for Accelerators (HFCC-A) includes The Higgs Factory Steering Committee for Accelerators (HFSC-A) with seven L2 topical areas. It is coordinated by leaders from seven National Laboratories. The HFSC-A comprised by Tor Raubenheimer (SLAC), Steve Gourlay (FNAL), Matthias Liepe (Cornell), and Jean-Luc Vay. The HFCC-A organization is shown in the figure below.
The L2 organizers are listed in the table below.

|---|---|---|
| Beam Physics | Ji Qiang (LBNL) | Vadim Sajaev (ANL) |
| Diagnostics and Instrumentation | Sasha Aleksandrov (ORNL) | Michiko Minty (BNL) |
| RF Systems | Sergey Belomestnykh (FNAL) | Maria Sanchez Barrueta (LANL) |
| Magnet Systems | Giorgio Ambrosio (FNAL) | Gianluca Sabbi (LBNL) |
| Machine Detector Interface (MDI) | Andrei Seryi (JLAB) | Spencer Gessner (SLAC) |
| Infrastructure & Engineering | Damien Dockery (FNAL) | Vasiliy Morozov (ORNL) |
| Integration & Sustainability | Roger Ruber (JLAB) | Mei Bei (SLAC) |
L2 Goals and Guidelines
- Identify potential areas where US can make significant and leading contributions.
- Expand on previous US achievements utilizing our expertise & capabilities.
- Collect input from community and encourage proposal submissions.
- Consider interplay with HFSC-PED and identify joint projects which benefit HFSC-A and HFSC-PED.
- Work with international project management teams to ensure the U.S. input is relevant and desired.
- For the FCC-ee, this includes the leaders of the FCC Feasibility Study and the Topical Groups.
- For the ILC, this includes the IDT WG2 leadership.
- Select a set of R&D topics that will contribute to the Higgs Factory designs while augmenting core capabilities in the US and, ideally, will lead to a significant role in a future construction project.
- Communicate with the broader accelerator community to encourage the development of proposals from US participants for collaboration on the FCC-ee, LCF, or ILC within the L2 subject area; since September 2025, the focus will be toward FCC-ee although topics with broad applicability are still of interest.
- Help develop criteria for proposal reviews and assist in the review process.
- Track progress and spending of the accepted proposals within the L2 subject area.
- Participate in the annual collaboration meetings and program progress reviews.
- Arrange an annual in-person meeting and quarterly virtual meetings focused on the specific L2 topics which might be combined with other L2's working on overlapping topics.
