Description
In order to increase the intensity in proton machines, the charge exchange injection scheme has been widely used since the 70's and is a crucial element in e.g. the high luminosity option discussed for the future of the LHC. The advantage of injecting particles in another charge state (H-) than the stored one (H+) is that it enables accumulation of like particles in an already occupied volume of phase-space. However, the charge exchange injection necessarily takes place by some means of stripping which may increase the emittance of the stored beam. In the seminar I will discuss the many advantages offered by e.g. channeling through the use of diamonds instead of amorphous carbon as the stripping medium.
