All-ion accelerators: An injector-free synchrotron

Abstract

Articles you may be interested inPreliminary physical and electromagnetic design for the injector of the heavy ion superconducting linaca) Rev. Sci. Instrum. 85, 02A709 (2014);A medium-energy synchrotron capable of accelerating all-ion species is proposed. The accelerator employs a strong focusing lattice for ion-beam guiding and induction acceleration for acceleration and longitudinal capture, which is driven by a switching power supply. All ions, including cluster ions in their possible and arbitrary charge state, are accelerated in a single accelerator. Since the switching power supply employing solid-state switching elements is energized by a trigger signal, which is generated from a bunch monitor signal produced by a circulating ion bunch, the induction acceleration always synchronizes with the bunch circulation. This feature enables the realization of an almost injector-free synchrotron.

Warm dense matter study and pulsed-power developments for X-pinch equipment in Nagaoka University of Technology

“…Pulsed-power development for point-spot-like X-ray source generated by X-pinch technique [26] For observing interior of dense plasmas generated by the intense ion beams or the pulsed-power discharges [27][28][29][30][31][32][33], we required intense, point-spot like X-ray source, because of short lifetime, small size and high density of those plasmas. One of the intense, point-spot like X-ray sources is X-pinch technique [34][35][36][37][38][39][40][41].…”

Induction acceleration scenario from an extremely low energy in the KEK all-ion accelerator

“…The KEK-AIA is almost an injector free synchrotron [3]. Only an ion source is required to provide ions.…”

“…It has been suggested in Ref. [3] that such a manipulation can be achieved by the pulse density control of the acceleration voltage pulse. Pulse density of the trigger signal to generate the acceleration voltage pulse is managed in such a manner that the effective acceleration voltage felt by the particles over a short time period is equal to the desired acceleration voltage.…”

“…The AIA, which is capable of accelerating all ions, including cluster ions of any possible charge state and mass, is under study [3]. The motivating factor is the numerous applications of the ion beam from the AIA ranging from material science, medical science, warm dense matter studies and mutagenesis.…”

Intelligent control system for the KEK digital accelerator

“…The all-ion accelerator (AIA) [2] is one example of the application of the induction synchrotron, which was proposed by Takayama and Kishiro in 2000 [1] and fully demonstrated by using the KEK 12 GeV proton synchrotron (PS) in 2006 [3]. Ions in the induction synchrotron are accelerated and captured with pulse voltages generated by transformers (induction acceleration cell, IC).…”
