ORIGIN: centred on the cradle and z = 0 at the level of the theoretical axis of the Tile sitting on the Cradle - I. Nikitine, October 2002 Ysu axis: The direction of the Y axis is defined by the line between the two centre points of the extreme supports of the cradle faces BACK and FRONT, Y is horizontal Xsu axis: The direction of the X axis is defined perpendicular to the Y axis and passing through the line centred on the 2 grooves (width 2mm) at the middle of the cradle plates, X is horizontal Zsu axis: The Z axis is vertical and is perpendicular to the X and Y axis, positive to the top See the document: EDMS number: ATL-LE-UR-0031

The Survey System was defined just after the Cradle installation

It was linked to the Cradle position at this moment

Survey System is not moving with the TILE/CRADLE/SADDLE

It is not changed during the preassembly, except some refresh


SURVEY SYSTEM DEFINITION

SU System is materialised by a survey network fixed to the stable structure of the Building 185

Survey network:• Survey points on the floor and 1m wall – far away from Tile – for vertical stability measurements• Survey brakets link to the Salève side wall, 2 levels• Survey tripods and brackets fixed to the Jura side survey towers, 2 levels

SU System is needed for the survey measurements (link to the vertical)

LOCAL SYSTEM OF TILE MODULES - FIDUCIALISATION

Origin for Extended Barrel Module: Middle of the bottom Girder edge on the ITC side;Origin for Barrel Module: Middle of the bottom Girder plane;

X axis: in the mean plane of the 4 girder reference points, perpendicular to the Y axis;Y axis: in the mean plane of the 4 girder reference points, coincided with the girder longitudinal axis;Z-axis: perpendicular to the mean plane of the 4 girder reference points, positive to the top.

PROPOSAL FOR A TILE SYSTEM LINK TO THE NOMINAL TILE GEOMETRYINSTALLED ON THE BEAM LINE INSIDE THE CAVERN


TO GIVE THE MEASURED XYZ IN THE TILE SYSTEM:

WE PROPOSE TO USE THE SADDLE END BEAM POINTS – CLOSE TO THE ATLAS RAILS - FOR THE CALCULATION OF THE TRANSFORMATION PARAMETERS

TRANSFORMATION OF MEASURED POINTSFROM SURVEY SYSTEM TO TILE SYSTEM

3D TRANSFORMATION FROM SYST A TO SYST B:

• Calculation of best fit translation and rotation parameters using a set of points known in both systems

• application of these parameters to all the points known in syst. A

Recent Proposal fromKathy Pommès and Matthew Sharp

Document under approvalTile Calorimeter Naming ConventionsATC-OP-QA-0004

Survey marker name = 4<equipment code>.<logical position>. <marker location>

Marker locations for all systems are of the form:SF_NN, where: S = Survey Marker; F = Face of Slot; NN = Marker position on face

For the Tile:<face> refers to the side of the module the marker is situated on: A or C<mark position> I, M or O, inner, middle or outer radius.
