Summary Report of H- Injection Session II

PDF Version Also Available for Download.

Description

The H<sup>-</sup> injection was invented many years ago and has since been successfully applied in many machines over the last decades. The challenge to the high intensity machines is how to reduce the injection loss, which is usually the major part of total beam losses in a machine. Painting, both longitudinal and transverse, is an effective way to reduce the space charge e#11;ects and to minimize losses. RF capture of a chopped beam also gives better e#14;ciency than adiabatic capture. To employ a 2nd harmonic rf system to atten the rf bucket shape is another commonly used scheme. To compensate ... continued below

Description

The H<sup>-</sup> injection was invented many years ago and has since been successfully applied in many machines over the last decades. The challenge to the high intensity machines is how to reduce the injection loss, which is usually the major part of total beam losses in a machine. Painting, both longitudinal and transverse, is an effective way to reduce the space charge e#11;ects and to minimize losses. RF capture of a chopped beam also gives better e#14;ciency than adiabatic capture. To employ a 2nd harmonic rf system to atten the rf bucket shape is another commonly used scheme. To compensate the capacitive space charge impedance by an inductive insert could be a new venture, but which is not discussed at the workshop due to time limitation. The foil physics is well understood. Simulations seem to be able to include all the important e#11;ects in it, including the space charge. The general feeling is that we are in a good position concerning H<sup>-</sup> injection studies. Although there remains a number of design issues, the knowledge, experiences and tools in our hand should be able to address each of them properly.
