The Head and Tail dump both receive the beginning and end of the proton beam provided by Linac4 whilst the portions of beams injected into each PSB ring are respectively proportional to the length of each PFN pulse the create the adequate orbit deflection into the PSB.

13. Present status and planning until end 2015 STATUS TODAY  One full PFN built in B.867  One generator rack controls implemented  Lab. test on a prototype PFN halted till all cabling finished.  Tests with full pulse length (620 µs) and nominal required current (1000 A) performed but to be repeated for thermal aspects. (with new power supply) NEXT STEPS  After FSU cabling, system to be restarted (with Fug power supply, 12kV, 800mA.  Check thermal performance  Integrate new power supply then on-going IGBT/PFN testing R.

16. Conclusion The new BI.DIS generators is now close to enter in their production phase in parallel with the completion of the design and prototype phase. Big production effort starting 2016. The aim is to have hardware ready by end 2016 Technical aspects still to be checked on full size PFN:  Thermal behaviour  Rise time Full working prototype in 867 by end 2015 and the goal of having the full system ready for installation end of 2016 should “almost” be met providing the manpower is made available.
