East Hall under construction - 1962 East Area Renovation Project Team meeting # 4 Beam Line Layout Johannes Bernhard / EN-EA, 18 -11 -2016

Beam Line Layout • Objectives • Beam parameters • Layout • Outlook / Studies Johannes Bernhard, 18. 11. 2016

Beam line layout objectives • Better cope with present and future physics requirements • Higher top momenta • Higher acceptance (5 x higher transmission than present lines) • Improve reliability by removing splitter magnet • Two north targets (T 9 + T 10/11) for higher flexibility • T 9 for high purity electron and hadron beams • T 11 optimised for CLOUD operation Johannes Bernhard, 18. 11. 2016

Beam line layout objectives • Reduce primary zone size • minimise dose rates to personnel • faster repair times by improving equipment accessibility irradia tions irradiati ons Johannes Bernhard, 18. 11. 2016

Primary beam / T 8 • Removed splitter • 3 destinations Synoptic • Target A (T 9) • Target B (T 10/T 11) • T 8 (Irradiations) • F 61 dump destination to be included • Keep multi-target design Target Material Length Diameter (mm) Be 200 10 + Al case Electron enriched W 3 Al 100 10 Electron enriched Be 3 3 Al 200 10 Hadron 4 air - - Empty 5 AL 20 10 Hadron Head 1 2 Comments Parameter Value Proton beam momentum [Ge.

Outlook and Studies • Beam line layout reflects present and future physics requirements • Studies for magnet apertures about to be completed, summary document in preparation • Example: Replacement of 2 MBPL/M 200 in T 9 by MCB possible M 200 MCB X X Y Y Open collimators Beam spot at T 9 experimental area • Small (acceptable) losses for very open momentum slit (dp/p > 5% setting) • No losses for standard operation Johannes Bernhard, 18. 11. 2016

Outlook and Studies • Beam line layout reflects present and future physics requirements • Studies for magnet apertures about to be completed, summary document in preparation • Studies completed for beam stoppers / stopper dumps • Typical beam profile on T 9 stopper dump for open collimators Johannes Bernhard, 18. 11. 2016

Outlook and Studies • Beam line layout reflects present and future physics requirements • Studies for magnet apertures about to be completed, summary document in preparation • Studies completed for beam stoppers / stopper dumps • Integration ongoing, next iteration of beatch files • Example: Clash BHZ 3 (T 8) and QDE 5 (F 62), resolved Johannes Bernhard, 18. 11. 2016
