Detailed Description

The manager class for TOTEM RP geometry.

See schema of TOTEM RP geometry classes

This is kind of "public relation class" for the tree structure of DetGeomDesc. It provides convenient interface to answer frequently asked questions about the geometry of TOTEM Roman Pots. These questions are of type:
a) If detector ID is xxx, what is the ID of corresponding station?
b) What is the geometry (shift, roatation, material, etc.) of detector with id xxx?
c) If RP ID is xxx, which are the detector IDs inside this pot?
d) If hit position in local detector coordinate system is xxx, what is the hit position in global c.s.?
etc. (see the comments in definition bellow)
This class is built for both ideal and real geometry. I.e. it is produced by TotemRPIdealGeometryESModule in IdealGeometryRecord and similarly for the real geometry

ID conversions (based on the class TotRPDetID)
detector ID = |arm|station|RP|det|, i.e. 4-digit decimal number
Roman Pot ID = |arm|station|RP|, i.e. two digits
station ID = |arm|station|
arm ID = |arm|
where

• arm = 0 (left, i.e. z < 0), 1 (right)
• station = 0 (147m), 1 (180m), 2 (220m)
• RP = 0 - 5; 0+1 vertical pots (lower |z|), 2+3 horizontal pots, 4+5 vertical pots (higher |z|)
• det = 0 - 9; u and v detectors alternating; inner (local) x-axis always parallel to strips, detector 1200 is such that local x-axis lies between global x and y axes
