Resolving beam transport problems in electrostatic accelerators

2014 This paper reviews problem areas in beam transmission which are frequently encountered during the design, operation and upgrading of electrostatic accelerators. Examples are provided of analytic procedures that clarify accelerator ion optics and lead to more effective beam transport. Suggestions are made for evaluating accelerator design with the goal of improved performance. OPTICS, POLAR...

On the traceably accurate voltage calibration of electrostatic accelerators

We describe in detail a calibration method for the terminal voltage of small accelerators used for ion beam analysis, with the elastic resonance of O()O at 3038 keV as the intrinsic measurement standard. The beam energy relative to this resonance is determined with a precision around 300 eV and an evaluated reproducibility of 1.0 keV. We show that this method is both robust and convenient, a...

The present status of chain charging systems operating in large electrostatic accelerators

2014 A charging chain consisting of alternate insulating and conducting segments is inherently a more uniform structure than a conventional woven fabric charging belt. Consequently, in terms of voltage stability caused by variations in the charging system, a chain should be superior to a belt. In addition, a chain produces no lint and little dust; it is relatively insensitive to moisture and th...

A Multi-ampere Heavy Ion Injector for Linear Induction Accelerators Using Periodic Electrostatic Focusing*

One of the key problems for the accelerator system for a heavy ion fusion (HIF) power plant is to provide a source of ions at the parameters, principally energy and intensity, that are well matched for the primary accelerator component. A promising candidate for the primary accelerator component is the linear induction accelerator (LIA). The LIA is well matched to the pellet requirements becaus...
