  1. CW neutron source Benjamin Cheymol, Angel Jesus Romero Serrano, Jesus Alonso, LaliTchelidze Benjamin Cheymol, Angel Jesus Romero Serrano, Jesus Alonso, Lali Tchelidze

  2. CW Neutron Source • Pulse length: CW • Average beam power: ~ 1.5 MW • Beam energy: 0.5 – 4 GeV • Particle type: p or H- Benjamin Cheymol, Angel Jesus Romero Serrano, Jesus Alonso, Lali Tchelidze

  3. Spallation For energies > 100 MeV, the neutron yield stays depends only on the beam power! Benjamin Cheymol, Angel Jesus Romero Serrano, Jesus Alonso, Lali Tchelidze

  4. Linac vs Cyclotron Cyclotron protons 600 MeV 2.5 mA Pros: Vey compact Relatively cheap Cons: Relatively high losses Hard to upgrade LINAC protons 1 GeV 1.5 mA Pros: Low losses Easy to upgrade Cons: long Expensive Benjamin Cheymol, Angel Jesus Romero Serrano, Jesus Alonso, Lali Tchelidze

  5. Linac vs Cyclotron 300 m – linac length 15 m – cyclotron diameter Jesus Alonso Benjamin Cheymol, Angel Jesus Romero Serrano, Jesus Alonso, Lali Tchelidze

  6. Cyclotron • ECR source + RFQ (Energy at the exit ~2.5MeV) • Need 2.5 mA • First solenoid to accelerate the beam to 72 MeV • 4 sectors cyclotron • Second Solenoid up to 600 MeV • 8 sectors cyclotron Jesus Alonso • Use the same RF frequency or all the different part (around 50 Mhz). • The RFQ will be a 4-rods RFQ. • The cyclotron frequency is much lower than the RF frequency. • injection on the nth harmonic • fRF=n*fcyclotron • The losses at the extraction of the cyclotrons must be controlled Benjamin Cheymol, Angel Jesus Romero Serrano, Jesus Alonso, Lali Tchelidze
