LQXF • Requirement: At 1.9 K, Magnetic Length = 4 m • The current design (suppose at 1.9 K):
CTE of Ti-6Al-4V (STA) • STA: Solution Treated 900-955ºC, Aged 540ºC. • L4 = 3.9106 m • y = f = -173.61 x 10-5 (T<24) • L293 = 3.9174 m • L293-L4 = 6.8 mm
Proposal Increase the length of one central pole by 7 mm ?
