Abstract
The aim of the CLIC Test Facility CTF3 at CERN is to demonstrate the feasibility of the key points of the two-beam acceleration based compact linear collider study. In particular, it addresses the efficient generation of a drive beam with the appropriate time structure of the electron bunches in order to produce high power rf pulses at a frequency of 30 GHz. This time structure requires a high bunch repetition frequency. It is obtained by successive injections of bunch trains into an isochronous ring using transversely deflecting rf structures. The major goal of the now completed first phase of the CTF3 was to achieve the bunch train combination at low charge. In this paper, we give a description of the project and summarize the experimental results, with a focus on the successful bunch frequency multiplication for various factors up to 5.
Highlights
The compact linear collider (CLIC) study [1] aims at a multi-TeV (0.5–5 TeV center-of-mass energy), high-luminosity (2–8 1034 cmÿ2 sÿ1) electron-positron collider for particle physics
The CLIC scheme is based on a two-beam acceleration concept where a high-frequency (30 GHz) high-gradient (150 MV=m) linear accelerator is powered by a low-energy (2.1 GeV), high-intensity drive beam running parallel to the main beam
One major challenge of the CLIC two-beam acceleration scheme is the generation of the drive beam electron pulses with the required high-current (150 A) and highfrequency bunch structures needed for 30 GHz rf power production
Summary
The compact linear collider (CLIC) study [1] aims at a multi-TeV (0.5–5 TeV center-of-mass energy), high-luminosity (2–8 1034 cmÿ sÿ1) electron-positron collider for particle physics. One major challenge of the CLIC two-beam acceleration scheme is the generation of the drive beam electron pulses with the required high-current (150 A) and highfrequency bunch structures needed for 30 GHz rf power production. CTF3 will provide a 30 GHz rf source with the CLIC nominal peak power and pulse length for component tests. It is being built in stages over several years from 2001 to 2007. A low current test of the bunch train combination was performed during 2001=02 in the first phase of CTF3 (the so-called Preliminary Phase), where the injection by rf deflectors into an isochronous ring and the multiplication of the bunch repetition frequency were demonstrated with short pulses. This paper describes the Preliminary Phase of CTF3 and presents the results of the experiments that were performed
