“…At that time we managed to calculate wakefields of a 1.8 mm bunch. Later this algorithm has been used to solve the wake potential problem of much shorter bunches and has proved to be quite powerful in describing the wakefields at the TESLA Liner Collider ( ¼ 0:7 mm) [12] and TESLA Test Facility FEL ( ¼ 25) [13]. Recently, we got an opportunity to make a comparison with wakefield measurements at Linac Coherent Light Source (LCLS) for a transport line [linac to undulator (LTU)] and undulator vacuum chamber.…”

We present and discuss the properties of the coherent electromagnetic fields of a very short, ultrarelativistic bunch in a rectangular vacuum chamber inside a bending magnet. The analysis is based on the results of a direct numerical solution of Maxwell's equations together with Newton's equations. We use a new dispersion-free time-domain algorithm which employs a more efficient use of finite element mesh techniques and, hence, produces self-consistent and stable solutions for very short bunches. We investigate the fine structure of the coherent synchrotron radiation fields. We also discuss coherent edge radiation. We present a clear picture of the field using the electric field lines constructed from the numerical solutions. This method should be useful in the study of existing and future concepts of particle accelerators and ultrafast coherent light sources, where high peak currents and very short bunches are envisioned.

“…This would increase the CMS energy of the ep collision by a factor 3-6 compared to HERA. A study on the possible luminosity which could be reached by using HERA in combination with the TESLA LC is given in [2] and amounts to roughly 10 31 cm −2 s −1 for a 250 GeV electron beam, assuming proton beam cooling with sufficiently small cooling times. The use of a dynamic focusing scheme could provide a potential luminosity upgrade by a factor 3-4, and further possible improvements are not excluded.…”
