Intro/Beamline concept (Winni)
- Dogleg extraction after bend in XTD3
- Current state of concept main "working components" are dipole magnets
- QH and QF triplets inserted at ~right numbers but position end fields require tuning
- Current concept horizontal only, in realistic one need vertical kick and vertical dipoles to guide back into photon beam pipe
- Could be sensible to redesign magnets especially in the overhead section in XTD3, to optimize weight
Talk on beam optics/dynamics calculation (Marin):
- First implementation based on list of magnets from Winnis concept with approximated positions and field strengths
- Simulation using Xsuite
- Quite large beta function in x and nonzero dispersion at the end
- Comments by Winni: acceptable beta function should be <100
- To optimize dispersion, consider subsections of the beamline step-by-step rather than all at once
- Switch to Ozelot tool (used by Plasma community, EuXFEL plans to use in the future), could ELBEX help pilot it?
Talk on CAD integration of beamline (Benno):
- Integration model in NX in place
- Exchange of information on placement of beamline elements via Excel table from simulation (--> need to define coordinate system for parts)
- Template is "long list" from Mad8 used by Winni for EuXFEL
- Different detail grades for placeholders, place holders with interfaces, inner component structure
- Could define place holder "corridor" for beamline which respects boundary conditions from tunnel etc.
Mounting constraints/Virtual Tunnel view (Daniel):
- https://vtour.xfel.eu/
- In XTD3, can only mount on metal rails in concrete Tuebbings, don't have metal arcs for welding like in XTL
- Tradeoff between number of anchor points to support more weight but also resulting in more weight of mount itself
- Can mount on the floor (example of photon beam pipe), but have to take care of escape routes and transport paths
Next meeting: 21st of August 10:00AM
- Discuss progress on the beamline design
- Beam parameter requirements from ELBEX users (Plasma, TB, LUXE)
There are minutes attached to this event.
Show them.
