A radio frequency driven H(-) source for Linac4

Area of Science:

• Particle accelerators
• High-intensity beams
• Particle sources

Background:

• CERN's accelerator chain requires upgrades for higher beam intensity and brightness.
• Linac4 is crucial for upgrading the proton accelerator facility.

Purpose of the Study:

• To develop a flexible two-source design for the H(-) linac.
• To accommodate new radio frequency quadrupole alternatives with varying injection energies.
• To meet a pressing linac schedule for the CERN accelerator upgrade.

Main Methods:

• Based the H(-) linac source on a copy of the DESY radio frequency driven H(-) source.
• Developed a flexible two-source design to allow for alternative radio frequency quadrupole configurations.

Main Results:

• A flexible two-source design for the H(-) linac was successfully developed.
• The design accommodates potential radio frequency quadrupole alternatives and varying injection energies.

Conclusions:

• The developed two-source design is essential for the Linac4 upgrade.
• This flexible approach supports future requirements for higher beam intensity and brightness at CERN.
