LEBIT Ion Optics
In the LEBIT research project a configuration of electrostatic ion optical elements is used to guide ions from a test ion source to an RFQ cooler/buncher. The present ion optical configuration is functional but the ion beam properties for injection into the buncher can still be improved. The computer program Simion 7.0 was used to optimize the present ion optics configuration and test new desig...
متن کاملIon optics with electrostatic lenses
Ion optics with electrostatic lenses is presented using the standard matrix formalism of magnetic ion optics. We introduce the paraxial ray equation which is appropriate to systems with rotational symmetry. The first-order solutions of the paraxial ray equation are derived. The resulting transport matrices can be used to study systems with acceleration tube lenses, aperture lenses, einzel lense...
متن کاملTransverse Ion Beam Shaping Using Nonlinear Optics
Taking an advantage of the unique capabilities of heavy ion beams and continuously increasing beam intensity, many successful experiments on high energy density (HED) matter have been carried out at GSI over the past few years. New fascinating experimental proposals such as investigation of equation-of-state of matter under extreme conditions [1] and generation of metallic hydrogen utilizing io...
متن کاملHiPEP Ion Optics System Evaluation Using Gridlets
Experimental measurements are presented for sub-scale ion optics systems comprised of 7 and 19 aperture pairs with geometrical features that are similar to the HiPEP ion optics system under development within NASA's Project Prometheus. Effects of hole diameter and grid-to-grid spacing are presented as functions of applied voltage and beamlet current. Recommendations are made for the beamlet cur...
متن کاملNumerical Simulation of HiPEP Ion Optics
The ffx code was used to investigate the lifetime and propellant throughput capability of the High Power Electric Propulsion (HiPEP) thruster ion optics as part of NASA’s Project Prometheus. Erosion predictions are presented as a function of beamlet current, accel grid voltage, and propellant utilization efficiency. These predictions were then compared to the lifetime goals of the thruster, and...
