Abbreviation:

HYB : Hybrid Technology (Permanent magnets & Soft Material)
PPM : Pure Permanent Magnet Technology
QP : Quasi Periodic Undulator
EMPHU: Electro Magnet Permanent Helical Undulator
SmCo: The magnetic material used for this undulator is Sm₂Co₁₇ instead of the NdFeB (which is typically used)

Remarks:

Each Undulator segment is approximately 1.65 m long with the exception of :

In-vacuum undulators (L= 2 m)
ID19 (W150: 1.12 m)

The magnetic field of an ID is given in this table for its minimum gap. For those with the same period, and when several segments have been produced by using the same design and technology, the B value returned is the average value. For more accurate results, please contact the ID group.
