Draft:

Present: Nicolas, A. Sinturel, Jose, Vincent M., Carlotta, Gunn, Teresa, Thibaut

Discussion:

  • Vincent presenting the CATIA model of the latest gunn design
  • Remove round holes from anode, we have enough opening for pumping from gun to upstream
  • Cathode back plate shape modified from round to square to improve thermo-mechanics and reduce thermal conduction, the material is inconel for this piece
  • Nicolas talked to A. Cherif for metrology, he doesn't see any issue in alignment checks during assembly
  • Teresa showed new thermal simulations for the gun ceramic brazing part - filler can absorb the stress, not an issue, a test can be done
  • Some small details discussed on mounting, mechanical forces while tightening flange etc
  • Can we make minor modofication of pierce electrode to help with alignment rod ? - Gunn will check with a simulation to see if it affects e-beam quality
There are minutes attached to this event. Show them.
