News and brief overview of Beamline plans for the next few months Vaia Papadimitriou Beamline Technical Board Meeting April 1, 2016

Waiting for CD3-A for the Far Site News Waiting for CD3-A for the Far Site Still limited funding for the Beamline in FY16; Preliminary Design to start in FY18; Have planned for a ramp up in the second half of FY17. In the mean time the scientific collaboration would like to try and implement at day one (if possible) a re-optimized design for better physics reach (similar to where we were in 2012 before the reconfiguration which forced us to reduce costs). Why we can possibly achieve it this time? Additional scientific and engineering effort and more monetary resources. 04.01.16 Vaia Papadimitriou | News and Plans

Scope of re-optimization to improve physics reach Target (longer) Horns (three) with different shapes and higher currents than NuMI Integration/mounting of target into horn, baffle mounting, etc. Horn support modules (three) Horn power supply (ies) Remote handling (casks, morgue capacity analysis, workcell,..) Absorber (same footprint or changed footprint) Modeling Developing alternative option of gas in target chase Radiation Protection Conventional Facilities Additional management 04.01.16 Vaia Papadimitriou | News and Plans

News Effort plan to achieve new conceptual design by Fy18: in document 1098: ~ $ 2M, ~ 10.4 FTE out of which 6 FTE in engineer/designer Message from Elaine McCluskey on March 22, 2016 related to Beamline re-optimization: 04.01.16 Vaia Papadimitriou | News and Plans

High level priorities for FY16: Today’s Goal Our default design points to an air-filled/air-cooled target chase, a helium filled decay pipe which is air-cooled and considering making it nitrogen cooled and a beam window separating the chase form the decay pipe. High level priorities for FY16: Complete corrosion effort Complete air releases work for a longer/wider target chase as decided Today’s goal is to discuss the latest corrosion results and the plan forward with these studies. 04.01.16 Vaia Papadimitriou | News and Plans

Target Hall/Decay Pipe Layout ~ 40% of beam power in target chase ~ 30% of beam power in decay pipe 50 TON CRANE DECAY PIPE UPSTREAM WINDOW WORK CELL Cooling panels DECAY PIPE SNOUT Beam Decay Pipe: 194 m long, 4 m in diameter, double – wall carbon steel, helium filled, air-cooled. 5.6 m Target Chase: 2.2 m/2.0 m wide, 34.3 m long air-filled and air & water-cooled (cooling panels). Sufficiently big to fit in alternative target/horns. Main alternatives for gas atmosphere: N2 or He 04.01.16 Vaia Papadimitriou | News & Plans
