  2. Drift Tubes towards Run II • Chambers • 172200 tubes Aachen IIIA, ATOMKI, Budapest, CIEMAT Madrid, Debrecen, IFCA Santander, INFN Bologna, INFN Padova, INFN Torino, NICPB Tallinn, Oviedo,UA Madrid, UM Kuala Lumpur. DT Authors moved from 95 in 2013 to 94 in 2014. Status on may 19th: Chamber Minicrates: 3200 channels recovered Chamber HV: 312 channels recovered Theta TRBs replacement in the 24 MB1s of YB±2 Sector Collector (RO and trigger) relocated out of UXC: installed 3500 optical links that make the RO and trigger outputs of all 250 DT chambers individually available in USC M.Dallavalle

  3. M&O-B 2013 } Some expenses (~70K) delayed to 2014 after relocation of important system parts from UXC to USC * Share: 484-10(Estonia)-5(Hungary)-16(Santander)= 453 (58.5% Italy, 23,7% Germany, 17,8% Spain) Malaysia still to be negotiated and included

  4. 2013 final balance Carry over Slightly negative balance Budget includes Alignment contribution of 30k for read out boards relocation and extra photogrammetry targets and miniMABextenstions + planned 50k hired manpower (expert on site) and 16k for personnel travels for LS1 work. 560 kCHFcarry over to 2014 of which 70 reserved for planned interventions (VME crates, DCS). 490 kCHF possible true integral residual. The averaged carry over in the period 2009-2014, amounts to ~9% of the yearly M&O-B DT budget.

  5. 2014-2018 plan • In 2015, after the end of the Long Shutdown 1, electronics in the experimental cavern will again become unaccessible, no extra expenses expected. • In 2015-2016 we will have to purchase 10 A877 PS units, since DT is the only user of these units and CAEN is going to drop production. • In the winter shutdowns 2015-2016 and 2016-2017 we plan intervening on the optical splitters of the Sector Collector in USC (RO Modules).

  6. Budget vs year Carryover to 2014 is 560k to which we subtract 70k which is being spent in 2014 instead of 2013. This brings our carryover to 490k. budget We propose a wash out of the carry over in the 2015-2019 period. Starting from the 2014 carryover of 490k, the carry over will be cleared in 2019 (assuming for 2019 the same budget of 2018) taking into account that we will overspend an extra 100k  for the optical splitter and the CAEN PS spare units in 2015-2016.  2009-2013 average budget = 470k/year (91% spent on average) With the present spending profiles we will have to use 420k in the years 2015-2019 from the carryover, and adding  100k for optical splitters and CAEN PS spares we will completely spend the present carryover. Still to be defined: the contribution of Malaysia, and a possible increase of the Estonia contribution, which will further reduce the contributions of the other FA.
