DESCRIPTION:Speakers: Yaroslav Gorbachev (Budker Institute of Nuclear Phys
 ics)\nThe new variable period undulator with unique design was developed a
 nd built recently at Budker INP. It will replace the electromagnetic undul
 ator being used now at the second FEL of the Novosibirsk FEL facility. As 
 the result the FEL tunability range will be substantially increased. In th
 is paper we present the results of the undulator magnetic field measuremen
 ts for different periods as well as discuss the ways to reduce field error
 s which include magnets sorting\, weakening of undulator edge poles and us
 ing of steering coils. Results of researches supported by RBRF grant 15-02
 -07776 were used in this work.\n\nhttps://indico.inp.nsk.su/event/24/contr
