"Open Rings" Endcap Layout

(Previously known by a number of different names e.g. "concentric diskettes".)

Motivation and Description

A couple of talks showing the basic idea: 2013-06-26_Burdin_Rings.pdf 2013-11-OpenRings3D-simple.png

and a later update with a more sophisticated layout: 2013-08-27_Jones_Lpool_Status.pdf.

Caculation of ring sizes

(J.Pater) using spreadsheet found below:

Using the same module dimensions given above, assuming the same active coverage as the quad-hex-hex LoI -layout disks (dimensions are in mm):

Physical outer radius of ring 2 modules: centres not corners - corners will extend further 315.2
Active outer radius of ring 2 modules: centres not corners 315.0
Active inner radius of ring 2 modules: centres not corners 274.6
Physical inner radius of ring 2 modules: centres not corners 274.4
Physical outer radius of ring 1 modules: centres not corners - corners will extend further 253.0
Active outer radius of ring 1 modules: centres not corners 252.7
active CENTRE of ring 2 modules 232.5
Active inner radius of ring 1 modules: centres not corners 212.3
Physical inner radius of ring 1 modules: centres not corners 212.1
Physical outer radius of ring 0 modules: centres not corners - corners will extend further 190.7
Active outer radius of ring 0 modules: centres not corners 190.5
Active inner radius of ring 0 modules: centres not corners 150.1
Physical inner radius of ring 0 modules: centres not corners 149.9
Number of modules per ring, rounded up to be divisible by 4 (front/back, left/right clamshell):

Ring 2: 60  
Ring 1: 48  
Ring 0: 36
