Detailed Description

Abstract description of layers in a FTD detector.


This assumes a symmetric layout of petals (isocelete(?) trapezoids), arranged in layers (disk) a z-position to IP.
The sensitive area is assumed to be inside the petals but can be positioned independently.

virtual int gear::FTDLayerLayout::getNSensors ( int  layerIndex) const
pure virtual

The number of sensors per petal on a specific layer - Sensor indexing is defined as follows: (illustrated here by a doublesided petal with 4 sensors) it starts with number 1: the sensor on the side facing the IP (the front), that is farthest from the xy - origin.

2 is the next sensor on the same side closer to the xy - origin. 3 is on the back ( the side not facing the IP ) and is back to back to sensor 1. 4 is then back to back to sensor 2.

If it were for exmaple 8 sensors on a doublesided petal, it would be (from outside to inside) 1,2,3,4 on the front and 5,6,7,8 on the back.

If it were 3 sensors on a singlesided petal, it would be just 1,2,3 on the front.

The position of the support in z direction in mm for the petalIndex petal in layer layerIndex - layer indexing starting at 0 from the layer closest to IP.

Petal indexing starting at 0 for the petal placed in the X-axis and grows with positive rotation around Z-axis. The position is defined in the centroid point of the support.
