  1. Beam position on the TIDVG2004-2014 • MKDV1 June 2004: 2 (was the firsts) – at 52 kV PFN • Operating voltage progressively set down from 49 to 47.3 kV PFN between June 2004 and • Oct. 2006 • MKDV1 Oct. 2006 : 1 - Operating voltage set to 40 kV PFN • Magnet MKDV1 roughly repaired during the 2006-2007 shutdown • Run 2007 at VPFN = 49 kV (TBC), no flashover • Run 2008 at VPFN = 49 or more ? kV, no flashover • Magnet MKDV1 exchanged – new one includes transition pieces and PT100 - during the • 2008-2009 shutdown • Run 2009 at VPFN = 49 kV (TBC), no flashover ? • Viliam’s modification on PFN and TMR to reduce the PFN voltage by 4% while keeping same kick • Run 2010 at VPFN = 47.5 kV, no flashover • MKDV2 Nov. 2011 : 1 ; no spare for MKDV2 (larger aperture) • End of run 2011 at VPFN = 39 kV, no flashover • MKDV2 reconditioned during SD 2011-2012 • Run 2012 at VPFN = 41.4 kV, no flashover • MKDV2 repaired during LS1 but not fullt tested (was long and difficult to condition)- • proposed VPFN = 41.4 kV • Before being 41.4 kV it was 44 kV • Run2 (2014) VPFN = 47.5 kV End 2012 – 41.4 kV Distributions truncated at 3s
