Detailed Description

Class used to describe the segmentation of the pixel and allow for conversion between cell id and position.

The class PixelDiodeMatrix represents what it calls a cell. In the context of this class a cell can either be just a simple cell as one would normally think of a pixel cell (eg a 50x400um or 50x600um cell) or it can be a container of multiple cells. To allow for different size cells and layout, it contains a lower cell, an upper cell and multiple middle cells. The middle cells are all the same (so all have the same size), but the upper and lower cells can be different and can have different size or be left out if they are not needed. The direction of replication is also specified (eta or phi direction). The size of the cells in the direction orthoganal to the replication direction must all be the same (there is no check for this though).

To help understand the structure and its use, consider the current pixel geometry. The pixel module has two cell sizes short and long cells. These are refered to as normal and big bellow. The long cells are in the region at the edge of the the FE chips in order to cover the gap between FE chips.

The assembly of this structure is done when building the sensitive detector in GeoModel in the class GeoPixelSiCrystal.

• normalCell (short pixel cell) 50x400um
• bigCell (long pixel cell): 50x600um
• singleChipRow (represents one row associated to a FE)
  • Size: phiWidth = 50um, etaWidth = 600*2+400*16) um = 7.6 CLHEP::mm
  • upper cell: bigCell
  • middle cells: 16 x normalCell
  • lower cell: bigcell
  • direction: eta
• singleRow (represents a row of cells covering the full length of the module)
  • Size: phiWidth = 50um, etaWidth = 8 * (600*2+400*16) um = 60.8 CLHEP::mm
  • upper cell: none
  • middle cells: 8 x singleChipRow
  • lower cell: none
  • direction: eta
• fullMatrix (represents the full module)
  • Size: phiWidth = 50 * 328 um = 16.4 CLHEP::mm, etaWidth = 60.8 CLHEP::mm
  • upper cell: none
  • middle cells: 328 x singleRow
  • lower cell: non
  • direction: phi

Each cell knows its total size and total number of child cells in the phi and eta direction. This is determined by totaling up these quantities when the object is constructed.

The structure allows for efficient navigation from cell number to position and vice-versa. There are two main methods which allow for this navigation: cellIdOfPosition() (from cell id to position) and positionOfCell() (from position to cell id).

As it is assumed that child cells fill up completely its parent, there is no range check in these methods. The methods are called from PixelDiodeMap where it first checks that is within range of the top level cell (refered to as the top level matrix).

PixelDiodeMatrix might inherit std::shared_ptr but needs to return std::shared_ptr of this pointer. To do this, std::enable_shared_from_this and shared_from_this() have to be used. https://en.cppreference.com/w/cpp/memory/enable_shared_from_this

See the description of these methods for more details.

cellIdOfPosition()

const PixelDiodeMatrix * InDetDD::PixelDiodeMatrix::cellIdOfPosition	(	const Amg::Vector2D &	relPosition,
		SiCellId &	cellId
	)		const

Return cell Id corresponding to a relative position within the matrix.

Description.

The cellId is modified and returns the id relative to the passed cellId. That is, it adds the relative cellId to the cellId passed to the function. A pointer to the correspond cell is returned. This can be used to get the size of the cell.

Overview of algoritm:

• Before calling this method on the top level matrix the 2D position is calculated relative to the bottom left corner.
• The method cellIdOfPosition is always called with the position relative to bottom left of the cell and the cell id of bottom left child cell. For the top level matrix this is the position (-halfWidth, -halfLength) and a starting cell id of (0,0).
• It first checks if it is in the lower cell (if it exists).
• If not, it determines which cell by dividing the position relative to the start of the cell array by the pitch in that direction.
• If it is beyond the range of the middle cells it is taken as being in the upper cell.
• The cell number is added to the cellId that is passed to the method
• Once the cell is determined the function is called recursively until it reaches a single cell.

Search diode matching the given cell id and compute its position.

Description.

Parameters

matrix	the diode matrix in which the search is started
cellId	the cell id relative to the given matrix
position	storage for the position of the diode.

Returns

pointer to the sub-matrix which is representative for the diode.

Overview of algoritm:

• It starts with the position of the bottom left corner of the cell. For the full matrix this is (-halfwidth,-halflength)
• It first checks if is in the lower cell (if it exists).
• If not it determines the bottom edge of the cell by multiplying the cell number by the pitch.
• If it is beyond the range of the middle cells it is taken as being in the upper cell.
• This position is then passed recursively to the same method until it reaches a single cell.
• At the end the 2D position is then transformed to the position relative to the module center.
