The Advanced Test Accelerator (ATA) Injector

Next Linear Collider Test Accelerator Injector Upgrade

The Advanced Photon Source Injector Test Stand Control System

The Advanced Photon Source (APS) primary and backup injectors consist of two thermionic-cathode rf guns. These guns are being upgraded to provide improved performance, to improve ease of maintenance, and to reduce downtime required for repair or replacement of a failed injector. As part of the process, an injector test stand is being prepared. This stand is effectively independent of the APS li...

Design of a Carbon Injector for a Medical Accelerator Complex

A design study of a 7 MeV/u C injector LINAC for a synchrotron for light-ion tumour therapy is presented. The injector consists of a 14.5 GHz ECR ion source, a LEBT line, a 216 MHz RFQ structure of 1.2 m length for acceleration from 6 keV/u to 300 keV/u and a subsequent 216 MHz IH drift tube LINAC of 4.0 m length for acceleration to 7 MeV/u. The IH structure consists of four drift tube sections...

The JLC Accelerator Test Facility

highest-priority project for the future. Research and development toward the design of such a machine has occurred at KEK for more than a decade. Two major areas of current accelerator R&D at KEK include the technologies needed to generate high-quality beams in an injector complex and high-power microwave technology required for the main linear accelerators. Because its particle bunches encount...

100 MeV Injector Cell for a Staged Laser Wakefield Accelerator

A 100 MeV electron laser wakefield injector based on a sub-millimeter gas cell is presented. The gas cell, used mainly to overcome the density inhomogeneity associated with gas jets, is capable of yielding a homogeneous plasma source with densities less than 2 x 10 cm. Sharp step plasma density boundaries were obtained by using the laser to drill the gas cell pinholes as small as 100 μm in diam...
