What is LC Vision and Why Should You Care?

2

LC Vision advocates for a Linear Collider as the world’s next collider.

  • Less expensive than the FCC (probably)
  • Ready to be built today
  • Can reach the TeV scale
  • Does not commit the HEP community to FCC-hh timeline (2070?) or cost ($50B?)

​

LC Vision will submit multiple documents to ESPPU

  • LC Physics Case and Long Term Plans
  • Linear Collider Facility at CERN

​

Advanced Accelerator Technology will be highlighted by the LC Vision document.

  • We can support LC Vision by explaining how Wakefield Accelerators can extend a future LC to the multi-TeV scale.
  • LC Vision supports the AAC community by highlighting the R&D and facilities needed to upgrade a future collider.

Requested Input for ESPPU Document

7

  1. Upgrades with Wakefield Accelerator Technology
    1. Booster or Afterburner scenario
      1. Concept
        1. Highlight tech developments and broader use of technology
      2. Timeline and Required R&D
      3. Civil construction and env. impact
    2. LC based fully on WFA technology
      • Concept
      • Timeline and Required R&D
      • Civil construction and env. impact

A lot of work has gone into writing previous documents for ESPP 2018, Snowmass 2021, LDG 2023, etc.

​

We should reference or adapt previous work where possible.

Additional cavern needed here.

Caverns needed for laser rooms?

R&D and Test Facilities

10

Which R&D topics can be tackled at existing test facilities?

  • Single-stage beam quality

​

Which cannot?

  • PWFA Staging
  • Positron acceleration in plasma
  • Beam-beam physics

​

Are there topics that require very high energy beams to test correctly?

  • Betatron radiation in plasma

Specific “asks”

11

A high energy test beam facility at a future Linear Collider would enable accelerator R&D with 100+ GeV beams.

A second IR would enable R&D on beam-beam physics and gamma-gamma collider.
