This could be achieved by injection from a higher energy H- linac. A new injector will require a high performance, high reliability, negative hydrogen ion source. This paper will present the requirements for such a source together with the first results for a prototype microwave driven source.

A cylindrical microwave cavity is used whose front and rear faces are meshed to allow the antiprotons and laser beams to enter. The cavity is embedded in a cryogenic helium gas target. Frequency tuning of 300 MHz with Q values of 2700-3000 was achieved using over-coupling and an external triple stub tuner. We also present Monte-Carlo simulations of the stopping distribution of antiprotons in the low-density helium gas using the GEANT4 package with modified energy loss routines.

The goals of this experiment were to provide frequency scaling data on high gradient phenomena at similar pulse lengths, and to measure the structure performance at the longer pulse lengths available at SLAC (the CLIC test facility, CTF II, could provide only 16 ns pulses for high power operation and 32 ns pulses for medium power operation). Earlier high gradient tests of 21 GHz to 39 GHz standing-wave, single cells indicated no significant frequency dependence of the maximum obtainable surface field [2]. The X-band scaling test would check if this was true for travelling-wave, multi-cell structures as well. For the experiment, the CLIC group at CERN built a 30 cell accelerating structure that consisted of copper cells and molybdenum irises that were clamped together. The structure was mounted in a vacuum tank and installed in the Next Linear Collider Test Accelerator (NLCTA) beam line at SLAC where it was operated at high power for more than 700 hours.

Operating at 50 Hz, it will serve both as a high performance injector for the complex of high energy accelerators, replacing the present PS booster, and as a high power proton driver for other physics applications like the generation of muons and neutrinos and/or radio-active ions. The potential of the SPL is presently being scrutinized and compared to other alternatives. A path of evolution is considered, beginning with the realization of a 3 MeV test facility, followed by the building of the 160 MeV front end of the SPL and finishing with the construction of the complete linac. The status of these investigations and the progress towards the SPL are summarized in this paper.

Moreover, in the longer term, an even higher beam brightness is required by all methods considered for increasing the LHC luminosity beyond the present ultimate level. Improvements and/or new processes are therefore needed, especially in the low energy accelerators. A number of solutions have already been imagined for the PS complex that involve new linac(s) or/and sophisticated beam gymnastics. The present capabilities and limitations of the accelerator chain are described. The needs of the possible LHC luminosity upgrades are outlined, the proposed improvements are explained and their features and performance are compared.

We developed a simulation model to study the interaction between beam and transverse feedback system in detail, bunch-by-bunch and turn-by-turn, considering the technical implementation at the SPS [1]. A numerical model is used as the non linear behaviour (saturation) and limited bandwidth of the feedback system, as well as the transient nature at injection and extraction, complicates the analysis. The model is applied to the practical case of the CNGS beam [2] in the SPS accelerator. This beam will be ejected from the SPS in two batches causing residual oscillations by kicker ripples on the second batch. This second batch continues to circulate for 50 ms (about 2170 turns) after the first batch has been extracted and oscillations are planned to be damped by the feedback system.

These intensities are at the limit of transverse beam stability at injection energy into the SPS and can lead to very fast transverse instabilities that have recently been observed. There has been a major effort to reduce the SPS impedance. We describe and review the results of transverse beam measurements performed in the SPS. This includes transverse impedance measurements based on coherent tune shifts and measurements of growth and decay rates of several head tail modes as function of chromaticity. We also comment on the effect of the flat chamber geometry.

To remove this bottleneck, a higher energy linac is proposed (called â€ﾜLinac4†) which will double the brightness and the intensity of the beam delivered by the PSB and ensure the â€ﾜultimate” beam is available for LHC. Linac4 will deliver H- ions at a kinetic energy of 160 MeV. It is designed to be usable as the front-end of a future multi-GeV multi-MW linear accelerator, the â€ﾜSuperconducting Proton Linac” (SPL). R&D for Linac4 is now actively taking place with the support of the European Union through the Joint Research Activity HIPPI (â€ﾜHigh Intensity Pulsed Proton Injectors”), and of three ISTC projects involving three major Russian laboratories (BINP, IHEP and ITEP) and two nuclear centres (VNIIEF and VNIITF).

Since the kicker pulse used to extract the first batch is not ideal, the second batch will suffer from some residual kick and will oscillate transversely. These oscillations will prevent the second batch, when extracted, hitting the target correctly. To minimize this effect the transverse feedback system can be used to damp the oscillations. In this paper we present results obtained from experiments performed in September 2004.

Prominent beam dynamical effects are coupled bunch instabilities caused for example by the vacuum chamber resistance. This paper describes a fast approximate calculation of the beam deflection due to the wake field which is built up by the vacuum chamber resistance and caused by a large number of previous bunches and/or bunch passages. The code has been implemented into the framework of the CNGS extraction simulations [1] and the results are compared with measurements [2].

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 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 five.

We present here some characteristic features of the Montague resonance by using first simulations obtained with MICROMAP and IMPACT under simplifying conditions. The challenges for the planned code benchmarking are discussed.

In this paper we discuss that an important contribution to the loss in bunched beams can be explained it terms of particles trapped into lattice and space charge driven islands. Dedicated experiments at the CERN-Proton Synchrotron to confirm the theoretical model have shown the existence of an emittance growth dominated regime for working points sufficiently far from the lattice resonance, and of a beam loss dominated regime for tunes very close to the resonance. While the emittance growth dominated regime has been investigated in previous studies [3], we focus here on the beam loss dominated regime and compare simulation results with measurements made in the CERN-Proton Synchrotron ring.

High-intensity proton bunches (~1.2 1011 p/b) with low longitudinal emittance (~0.2 eVs) are affected by heavy losses after less than one synchrotron period. Such phenomenon has already been observed with leptons in many machines, e.g. in the SPS, or with protons at transition, e.g. in the CERN Proton Synchrotron (PS). However, to the authors’ knowledge, it is the first time with protons far from transition. The absence of transverse mode-coupling instability in hadron machines is generally explained by three mechanisms: (i) the intensity threshold for the longitudinal microwave instability is generally lower than for the transverse mode-coupling instability, (ii) the intensity threshold due to mode-coupling between the two lowest azimuthal modes increases with space charge, and (iii) the intensity threshold increases with bunch length (in the long-bunch regime). In this talk measurements performed in the SPS are compared to analytical and simulation predictions.

This is usually accomplished by comparing simulation results against available theories, and more importantly, against experimental observations. To this aim, a number of well-defined test cases, obtained by accurate measurements made in existing machines, are of great interest. Such measurements have been made in the CERN Proton Synchrotron to probe three space-charge effects: (i) transverse emittance blow-up due to space-charge induced crossing of the integer or half-integer stop-band, (ii) space-charge and octupole driven resonance trapping, and (iii) intensity-dependent emittance transfer between the two transverse planes. The last mechanism is discussed in detail in this paper and compared to simulation predictions.

For the first time the meeting was held at CERN and used the InDiCo system to manage the presentations. The theme of the workshop was 'issues affecting the efficiency of beam commissioning'. Most sessions lasted for half a day, but the two sessions covering magnets and machine protection issues were spread over 3 half days. In the final session on the Friday afternoon, outstanding issues were discussed and the decisions resulting from the week were recorded. Summaries of the sessions were presented in the main auditorium at CERN ten days after the workshop.
