• Jay Benesch, A quick and dirty magnet design for the magnetized beam LDRD proposal (December 27, 2015): media:LDRD_pair_Dec2015.pdf

 Bz(z) of four designs: media:Gun_Magnet_four_models_B.ods

• MPT solenoid available (pic Media:MPT5D04.JPG)

Specs at 100A (field map here Media:MPT5D04.xlsx) and operated to 125A
   B2L = 3.691E+07 G2-cm
   BL = 2.436E+04 G-cm
   B0 = 1.887E+03 G

Thin lens approximation (check my arithmetic)
  f[cm] = 1.206E+04 x (p[MeV/c)/I[A])^2

• Gun operated at 325 kV for 72 hr with pure alumina (white) R30 inverted insulator + shed & full electrode assembly:
