Performance of closed orbit feedback systems with spatial model mismatch
Sajjad Hussain Mirza, Rahul Singh, Peter Forck +1
Closed orbit feedback (COFB) systems used for the global orbit correction rely on the pseudo-inversion of the orbit response matrix (ORM). A mismatch between the model ORM used in…

Smoothing of the slowly extracted coasting beam from a synchrotron
Rahul Singh, Peter Forck, Stefan Sorge
Slow extraction of beam from synchrotrons or storage rings as required by many fixed target experiments is performed by controlled excitation and feeding of a structural lattice re…

Space-charge distortion of transverse profiles measured by electron-based Ionization Profile Monitors and correction methods
Dominik Vilsmeier, Mariusz Sapinski, Rahul Singh
Measurements of transverse profiles using Ionization Profile Monitors (IPMs) for high brightness beams are affected by the electromagnetic field of the beam. This interaction may c…
