A cw Heavy Ion Linac Based on Superconducting CH-Structures

According to the Unilac upgrade program for the SHE research at GSI, a new high energy part of the High Charge State Injector (HLI) has to be worked out. One of the versions of this linac foresees the acceleration of the highly stripped ions with charge-to-mass ratio of 1/6 delivered from the existing HLI at 1.4 MeV/u. The output beam energy should allow experiments at the Coulomb barrier and i...

Multicusp Ion Source for Induction Linac Applications

At LBNL we are investigating the use of gaseous ion sources for induction linac applications such as heavy ion inertial fusion. Typical requirements for the ion source is to produce 20 μs pulses with a rise-time of 2 μs. The current density should be greater than 100 mA/cm2 at a duty cycle of 10 Hz [1]. Noble gases such as krypton, neon and xenon will be used. The source used for the measuremen...

An Overview of Linac Ion Sources*

This paper discusses ion sources used in high-dutyfactor proton and H Linacs as well as in accelerators utilizing multi-charged heavy ions, mostly for nuclear physics applications. The included types are Electron Cyclotron Resonance (ECR) sources as well as filament and rf driven multicusp sources. The paper does not strive to attain encyclopedic character but rather to highlight major lines of...

Induction Linac Drivers for Heavy Ion Fusion*

The Heavy Ion Fusion Accelerator Research (HIFAR) program of the USDOE has for several years concentrated on developing linear induction accelerators as Inertial Fusion (IF) drivers. This accelerator technology is suitable for the IF application because it is readily capable of accelerating short, intense pulses of charged particles with good electrical efficiency. The principal technical diffi...
