Radio Undularor edit
The term is also encountered in high-speed morse operation, eg a "Printing Undularor".

Use edit
Article is a bit short on information, I think it should mention what the device is used for, and why. --GalFisk 09:46, 20 June 2006 (UTC)
Distinction between undulator and wiggler edit
I thing the distinction between both should be k>1 and k≤1 (indstead of k≫1 and k≪1) because at k=1 the radiation cones start overlaying. Anyway, in the current description, what would a device with k≈1 be called? — Preceding unsigned comment added by 141.34.3.113 (talk) 09:31, 19 August 2013 (UTC)
diagram incorrect? edit
The undulator picture does not follow the right hand rule for Lorentz force, assuming the arrows indicate B field direction and the particle beam is composed of electrons (as stated in the caption). — Preceding unsigned comment added by 157.82.193.71 (talk) 07:35, 22 March 2017 (UTC)
- I noticed the same too. The particle deflection is shown opposite to what is expected from Lorentz force. Can someone verify it and correct if needed? 174.16.196.10 (talk) 18:51, 10 January 2023 (UTC)
