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.

3. 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

4. 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:

5. 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.

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
