1 OLYMPUS Collaboration Meeting Luminosity Monitor Symmetric Möller/Bhabha Calorimeter David Rodríguez Piñeiro HIM / Mainz University OLYMPUS Collaboration Meeting DESY 26. 04. 2011

2 Symmetric Möller/Bhabha 26/04/2011David Rodríguez Piñeiro - Mainz University - OLYMPUS Meeting2 1.- New Beam Pipe Design 2.- New SYMB Design 3.- Main Support 4.- Interferences 5.- Summary

3 Symmetric Möller/Bhabha 26/04/2011David Rodríguez Piñeiro - Mainz University - OLYMPUS Meeting3 1.– New Beam Pipe Design

4 Symmetric Möller/Bhabha 26/04/2011David Rodríguez Piñeiro - Mainz University - OLYMPUS Meeting4 Cone pipe with SYMB windows: Difficult and expensive to manufacture Traditional design

5 Symmetric Möller/Bhabha 26/04/2011David Rodríguez Piñeiro - Mainz University - OLYMPUS Meeting5 Windows shorter Cone (due to Wakefield suppressor) inside the beam pipe

6 Symmetric Möller/Bhabha 26/04/2011David Rodríguez Piñeiro - Mainz University - OLYMPUS Meeting6 2.– New SYMB Design

7 Symmetric Möller/Bhabha 26/04/2011David Rodríguez Piñeiro - Mainz University - OLYMPUS Meeting7 Shifted ~350 mm upstream Adapted to the new enviroment Collimator and Lead Wall not aligned Boxes move away from the beam in diagonal Alignment system reordered

8 Symmetric Möller/Bhabha 26/04/2011David Rodríguez Piñeiro - Mainz University - OLYMPUS Meeting8 In the new position

9 Symmetric Möller/Bhabha 26/04/2011David Rodríguez Piñeiro - Mainz University - OLYMPUS Meeting9 Safety Factor: SF Total Displacement: TD SF > 7 TD < 0,05 mm SF > 8 TD < 0,04 mm SF> 6 TD: 0,0007 mm

10 Symmetric Möller/Bhabha 26/04/2011David Rodríguez Piñeiro - Mainz University - OLYMPUS Meeting10 Hallo Counter Further check

11 Symmetric Möller/Bhabha 26/04/2011David Rodríguez Piñeiro - Mainz University - OLYMPUS Meeting11 3.– Main Support

12 Symmetric Möller/Bhabha 26/04/2011David Rodríguez Piñeiro - Mainz University - OLYMPUS Meeting12 Will fit with this shape Will be made out of standard aluminum profiles Adaptad to the new enviroment

13 Symmetric Möller/Bhabha 26/04/2011David Rodríguez Piñeiro - Mainz University - OLYMPUS Meeting13 Longer in Z Still laying on the tubular supporting beams Due to interferences it will be mounted in place

14 Symmetric Möller/Bhabha 26/04/2011David Rodríguez Piñeiro - Mainz University - OLYMPUS Meeting14 4.– Interferences

15 Symmetric Möller/Bhabha 26/04/2011David Rodríguez Piñeiro - Mainz University - OLYMPUS Meeting15 SYMB OLYMPUS No clash detected Just 0 contact on the tubular supporting beams

16 Symmetric Möller/Bhabha 26/04/2011David Rodríguez Piñeiro - Mainz University - OLYMPUS Meeting16 Top View MWPC ToF Frame Beam Pipe Coils Frame

17 Symmetric Möller/Bhabha 26/04/2011David Rodríguez Piñeiro - Mainz University - OLYMPUS Meeting17 Tight clearances, but feasible

18 Symmetric Möller/Bhabha 26/04/2011David Rodríguez Piñeiro - Mainz University - OLYMPUS Meeting18 Mounted in place Optimized design to avoid overlapping parts

19 Symmetric Möller/Bhabha 26/04/2011David Rodríguez Piñeiro - Mainz University - OLYMPUS Meeting19 Cables to the ceiling? Tubular support attached to ToF frame Flasher box? Flasher box

20 Symmetric Möller/Bhabha 26/04/2011David Rodríguez Piñeiro - Mainz University - OLYMPUS Meeting20 New beam pipe design => New SYMB design New position: ~350 mm upstream Not interference with other subsystems (Hallo Counter study) Attached to the tubular supporting beams (longer in Z towards the beam) Summary

21 Symmetric Möller/Bhabha 26/04/2011David Rodríguez Piñeiro - Mainz University - OLYMPUS Meeting21 Personal Contact: d.rodriguezpineiro@gsi.de Tel: +49 (0) 6159171/1634 web.mit.edu/OLYMPUS Thank you! Frank Maas Sebastian Baunack Dmitry Khaneft Boris Gläser Eric Göbel Yue Ma Roberto Pérez
