1. M. Calvi & Th. Schmidt :: Insertion Device :: Paul Scherrer Institut
Meeting SLS 2.0
Villigen PSI, July 13 , 2016

2. Agenda Number of available IDs
Heat-load issues regarding flux/unit area
Short period undulators and use of whole harmonic flux
Energy gaps between low harmonics – who this would effect?
Performance of future APPLE devices, particularly regarding speed of polarisation switching
SIS permanent magnet undulator
Altera
