X-Ray Survey of The ATLAS SCT
The ATLAS Semi-Conductor Tracker
Alignment Requirements Error in Track Parameter measurements should not exceed 20% Miss-alignment of SCT must not exceed the following tolerances 1220050 SCT Wheels 1250100 SCT Barrel Rø(μm)Z(μm)R(μm)
Alignment Techniques Initial X-Ray Survey Frequency Scanning Interferometry Track-Based Alignment Procedures
Aims of The X-Ray Survey Produce a map of the SCT modules Calibrate the FSI system Provide a starting point for Track Alignment
X-Rays and SCT Modules SCT modules not optimised for X- Rays Wide beam used to compensate Beam profile sacrifices Z resolution Strip position (Rø) Signal e 50μm 2mm
X-ray Survey Overview
Positioning the Scanning Head Z – Positioning Stage Ø - Positioning Stage X-Ray Assembly Optical strip reader Laser Alignment
Barrel Survey Ø and Z fixed by scanning head R found through use of stereo angle between X-Ray tubes
End Cap Survey Different X-Ray assembly required Ø and Z fixed by scanning head R found by Illuminating modules from two Z positions R θ1θ1 θ2θ2 Z – axis Z1Z1 Z2Z2
Summary X-Ray Survey is an alignment procedure for the ATLAS SCT X-Ray trajectories follow those of actual events The Majority of the hardware is already in place
