[Sneap] Quadrupole Lens

[Chris Westerfeldt]

Ludwig.
    Is there a part number on the coil itself?  I used to have a couple of
spare coils for either a 2" or 3" HVEC quad.  I will check the number on
them.  I do have a 3" HVEC Quad doublet : D-MAG-321 I believe.  It has 10"
poles and is 30" overall.
You might also contact the MP lab at Minnesota.  They are in the process
of deciding how to decommission that lab and may have a spare coil or a
quadrupole available.
Regards,
- Chris
