26. DESICION ABOUT VERTICAL POSITION OF THE LINAC HAS BEEN TAKEN

27. Construction of the Linac support is finished and is currently under mechanical stress simulations
Design includes target chamber, linac can be regulated +/-8mm in each direction with possibility for additional, small tilt
Magnetic transporter must be verified due to collision with the bunker

32. Klystron localisation ?
„By choosing a different IGBT 3,3kV rating instead of 1,7kV rating the IGBT will withstand Neutron radiation. We have several systems installed operating for long time with neutrons without failing.”
Still, it is known that high dose of radiation will discolor the optical fibers and it can degenerate some sensitive microprocessors and memories. Keeping the radiation level low is therefore always a good idea to ensure longlife operation without any defects.

35. Time schedule
Delay in construction of the bunker and linac –vertical position of the linac decided in end of June
Delay in the offer for klystron (finally achieved in June)
Then stacked in our purchasing dept.
Klystron modulator ordered – delivery in April 2016
First tests possible on our klystron (lower power), but full integration will take place in May 2016.
