160 MeV H- injection into the CERN PSB
The H- beam from the proposed LINAC4 will be injected into the four existing rings of the PS Booster at 160 MeV. A substantial upgrade of the injection region is required, including the modification of the beam distribution system and the construction of a new H- injection system. This paper discusses beam dynamics and hardware requirements and presents the results of optimisation studies of the injection process for different beam characteristics and scenarios. The resulting conceptual design of the injection region is presented, together with the main hardware modifications and performance specifications.
Design and Development of Separation Septa for the CERN PS Booster Upgrade
The CERN PS Booster project foresees the injection of 160 MeV H- ions into the booster from Linac 4. For this substantial upgrade, a system of 5 pulsed magnets (BIDIS) and 3 vertical septa (BISMV) will distribute the Linac pulses into the four-vertically separated Booster injection lines before being injected into the rings. This paper describes the magnetic calculations and the design concept that will be used in the future upgrade of the BISMV. Subsequently the mechanical design of the septa and their integration into the existing transfer line will be discussed.
The Multiturn Charge Exchange Injection System for the Fermilab Booster Accelerator
Since March 1978 the Fermilab Booster has operated with H-multiturn charge exchange injection. A record number of protons per Booster cycle has been injected and accelerated to 8 GeV. The details of the injection system are discussed as well as the Booster performance and the reliability of the method.
