[Sneap] Acceleration Tube Damage

[Frank Chmara]

Hi Ian

Vinyl acetate is what was used to originally assemble the tubes.  If you want to try this approach to repair your tube,  we have some vinyl acetate beads that we can provide to you.  Just let me know.

Regards,

Frank

  SNEAPers,

  We have a 2.5 MeV HVE Van de Graff accelerator, but our acceleration tube is slighly damaged.  It has a gouge in it that is ovular in shape (~1"x.5") and goes about half of the way into the tube glass, from inside to out.  Does anyone know of anything we can use to repair it with?  Somone suggested using Vinyl Acetate Resin disolved in toluene to repair the damage.  Is this a viable method for the repair?  If so does anyone know the name of a supplier because I am having trouble finding someone to supply the resin form of vinyl acetate.  Does the tube even need to be repaired, it will hold 10^-6 torr for its vacuum, we are just worried that once we put it under vacuum and 125psi that the tube will break.  

  Thanks in advance,
  Ian Rice
