Points & Sectors Points –Point: a singularity on the perimeter with experimental or technical caverns, access shafts, technical area at ground level –Each point is named by a letter, from A to L clockwise in alphabetical order Sectors –Sector: the length of machine between two Points –Each Sector is named by two letters indicating the Point where it originates and the Point where it terminates, clockwise –Sectors have different lengths (see below) and Functional Sections P. Lebrun & J. OsborneFCC I&O meeting Sector length [km] P = 80.0 kmP = 86.6 kmP = 93.3 kmP = km AB, FG, GH, LA5.4 BC, EF, HI, KL CD, DE, IJ, JK

Functional Sections –Functional Section: part of a sector with a given structure or function –Types of Functional Sections have generic names –A particular Functional Section has a name defined as: - (- ) Examples: LSS-A, ESS-D, DS-AB-1, DS-CD,… –Functions allocated to Functional Sections are given in following P.
