Namespaces
namespace	concept
namespace	detail
	These functions perform the transport of a covariance matrix using given Jacobians. The required data is provided by the stepper object with some additional data. Since this is a purely algebraic problem the calculations are identical for StraightLineStepper and EigenStepper. As a consequence the methods can be located in a seperate file.

	)

Global method which creates the TrackingGeometry from DD4hep input.

This method returns a std::unique_ptr of the TrackingGeometry from the World DD4hep DetElement.

Precondition

Before using this method make sure, that the preconditions described in DD4hepPlugins are met.

Parameters

[in]	worldDetElement	the DD4hep DetElement of the world
[in]	loggingLevel	is the debug logging level of the conversion and geometry building
[in]	bTypePhi	is how the sensitive surfaces (modules) should be binned in a layer in phi direction.

Note

Possible binningtypes:

• arbitrary - of the sizes if the surfaces and the distance inbetween vary. This mode finds out the bin boundaries by scanning through the surfaces.
• equidistant - if the sensitive surfaces are placed equidistantly

equidistant binningtype is recommended because it is faster not only while building the geometry but also for look up during the extrapolation

Parameters

[in]	bTypeR	is how the sensitive surfaces (modules) should be binned in a layer in r direction
[in]	bTypeZ	is how the sensitive surfaces (modules) should be binned in a layer in z direction
[in]	layerEnvelopeR	the tolerance added to the geometrical extension in r of the layers contained to build the volume envelope around
[in]	layerEnvelopeZ	the tolerance added to the geometrical extension in z of the layers contained to build the volume envelope around
[in]	defaultLayerThickness	In case no surfaces (to be contained by the layer) are handed over, the layer thickness will be set to this value

Note

Layers containing surfaces per default are not allowed to be attached to each other (navigation will fail at this point). However, to allow material layers (not containing surfaces) to be attached to each other, this default thickness is needed. In this way, the layer will be thin (with space to the next layer), but the material will have the'real' thickness.

Attention

The default thickness should be set thin enough that no touching or overlapping with the next layer can happen.

Parameters

[in]	sortSubDetectors	std::function which should be used in order to sort all sub detectors (=all Detelements collected by the method collectSubDetectors()) from bottom to top to ensure correct wrapping of the volumes, which is needed for navigation. Therefore the different hierachies need to be sorted ascending. The default is sorting by ID.
	matDetcroator	is the material decorator that loads material maps

Exceptions

std::logic_error

if an error in the translation occurs

Returns

std::unique_ptr to the full TrackingGeometry * The Tracking geometry needs to be built from bottom to top to ensure Navigation. Therefore the different hierachies need to be sorted ascending. Per default the sub detectors are sorted by the id of their dd4hep::DetElement. In case another sorting needs to be applied, the users can provide their own function

Method to setup the FieldMapper

Parameters

localToGlobalBin

Function mapping the local bins of r,z to the global bin of the map magnetic field value

e.g.: we have small grid with the values: r={2,3}, z ={4,5}, the corresponding indices are i (belonging to r) and j (belonging to z), the globalIndex is M (belonging to the value of the magnetic field B(r,z)) and the field map is:

r	i	z	j	B(r,z)	M
2	0	4	0	2.323	0
2	0	5	1	2.334	1
3	1	4	0	2.325	2
3	1	5	1	2.331	3

In this case the function would look like:

[](std::array<size_t, 2> binsRZ, std::array<size_t, 2> nBinsRZ) {
   return (binsRZ.at(0) * nBinsRZ.at(1) + binsRZ.at(1));
}

Values of the grid points in r

Note

The values do not need to be sorted or unique (this will be done inside the function)

The magnetic field values inr r and z for all given grid points stored in a vector

Note

The function localToGlobalBin determines how the magnetic field was stored in the vector in respect to the grid values

Parameters

[in]	lengthUnit	The unit of the grid points
[in]	BFieldUnit	The unit of the magnetic field
[in]	firstQuadrant	Flag if set to true indicating that only the first quadrant of the grid points and the BField values has been given and that the BFieldMap should be created symmetrically for all quadrants. e.g. we have the grid values r={0,1} with BFieldValues={2,3} on the r axis. If the flag is set to true the r-axis grid values will be set to {-1,0,1} and the BFieldValues will be set to {3,2,3}.

Method to setup the FieldMapper

Parameters

localToGlobalBin

Function mapping the local bins of x,y,z to the global bin of the map magnetic field value

e.g.: we have small grid with the values: x={2,3}, y={3,4}, z ={4,5}, the corresponding indices are i (belonging to x), j (belonging to y) and k (belonging to z), the globalIndex is M (belonging to the value of the magnetic field B(x,y,z)) and the field map is:

x	i	y	j	z	k	B(x,y,z)	M
2	0	3	0	4	0	2.323	0
2	0	3	0	5	1	2.334	1
2	0	4	1	4	0	2.325	2

3	1	4	1	4	0	2.325	6
3	1	4	1	5	1	2.331	7

In this case the function would look like:

[](std::array<size_t, 3> binsXYZ, std::array<size_t, 3> nBinsXYZ) {
  return (binsXYZ.at(0) * (nBinsXYZ.at(1) * nBinsXYZ.at(2))

T Acts::interpolate ( const Point1 &  position, const Point2 &  lowerCorner, const Point3 &  upperCorner, const std::array< T, N > &  values  )

inline

performs linear interpolation inside a hyper box

Template Parameters

T	type of values to be interpolated
N	number of hyper box corners
Point1	type specifying geometric positions
Point2	type specifying geometric positions
Point3	type specifying geometric positions

Parameters

[in]	position	position to which to interpolate
[in]	lowerCorner	generalized lower-left corner of hyper box (containing the minima of the hyper box along each dimension)
[in]	upperCorner	generalized upper-right corner of hyper box (containing the maxima of the hyper box along each dimension)
[in]	values	field values at the hyper box corners sorted in the canonical order defined below.

Returns

interpolated value at given position

Precondition

position must describe a position inside the given hyper box, that is .

Note

• Given U and V of value type T as well as two double a and b, then the following must be a valid expression a * U + b * V yielding an object which is (implicitly) convertible to T.
• All Point types must represent d-dimensional positions and support coordinate access using operator[] which should return a double (or a value which is implicitly convertible). Coordinate indices must start at 0.
• N is the number of hyper box corners which is where is the dimensionality of the hyper box. The dimensionality must be consistent with the provided Point types.
• Definition of the canonical order for sorting the field values: The hyper box corners are numbered according to the following scheme. Each corner is defined by the set of lower/upper boundary limits in each dimension i. This can be represented by a binary code (from left to right) where a 0 stands for a lower bound along this axis and a 1 stand for the upper bound along this axis. The left most bit corresponds to the first dimension and the bits to the left correspond to the 2nd, 3rd... dimension. The binary code can be interpreted as integer which gives the number of the corresponding hyper box corner. The field values are ordered according to ascending hyper box corner numbers.
  As an example assume we have a 3D box with lowerCorner = (1,2,3) and upperCorner = (4,5,6). The eight corners with their bit patterns and corner numbers are:
  • (1,2,3): 000 = 0
  • (1,2,6): 001 = 1
  • (1,5,3): 010 = 2
  • (1,5,6): 011 = 3
  • (4,2,3): 100 = 4
  • (4,2,6): 101 = 5
  • (4,5,3): 110 = 6
  • (4,5,6): 111 = 7

decltype(Callable<N>::invoke(std::declval<Args>()...)) Acts::template_switch	(	size_t	v,
		Args &&...	args
	)

Dispatch a call based on a runtime value on a function taking the value at compile time.

This function allows to write a templated functor, which accepts a size_t like paramater at compile time. It is then possible to make a call to the corresponding instance of the functor based on a runtime value. To achieve this, the function essentially created a if cascade between N and NMAX, attempting to find the right instance. Because the cascade is visible to the compiler entirely, it should be able to optimize.

Template Parameters

Callable	Type which takes a size_t as a compile time param
N	Value from which to start the dispatch chain, i.e. 0 in most cases
NMAX	Maximum value up to which to attempt a dispatch

Parameters

v	The runtime value to dispatch on
args	Additional arguments passed to Callable::invoke().

Note

Callable is expected to have a static member function invoke that is callable with Args

		BinningType	bTypeR = equidistant,
		BinningType	bTypeZ = equidistant,
		double	layerEnvelopeR = UnitConstants::mm,
		double	layerEnvelopeZ = UnitConstants::mm,
		double	defaultLayerThickness = UnitConstants::fm
	)

Method internally used to create an Acts::CylinderVolumeBuilder.

This method creates an Acts::CylinderVolumeBuilder from a sub detector (= 'compound' DetElement or DetElements which are declared as 'isBarrel' or 'isBeampipe' by their extension.

Parameters

[in]	worldDetElement	the DD4hep DetElement of the world
[in]	loggingLevel	is the debug logging level of the conversion and geometry building
[in]	bTypePhi	is how the sensitive surfaces (modules) should be binned in a layer in phi direction.

Note

Possible binningtypes:

• arbitrary - of the sizes if the surfaces and the distance inbetween vary. This mode finds out the bin boundaries by scanning through the surfaces.
• equidistant - if the sensitive surfaces are placed equidistantly

equidistant binningtype is recommended because it is faster not only while building the geometry but also for look up during the extrapolation

Parameters

[in]	bTypeR	is how the sensitive surfaces (modules) should be binned in a layer in r direction
[in]	bTypeZ	is how the sensitive surfaces (modules) should be binned in a layer in z direction
[in]	layerEnvelopeR	the tolerance added to the geometrical extension in r of the layers contained to build the volume envelope around
[in]	layerEnvelopeZ	the tolerance added to the geometrical extension in z of the layers contained to build the volume envelope around
[in]	defaultLayerThickness	In case no surfaces (to be contained by the layer) are handed over, the layer thickness will be set to this value

Note

Layers containing surfaces per default are not allowed to be attached to each other (navigation will fail at this point). However, to allow material layers (not containing surfaces) to be attached to each other, this default thickness is needed. In this way, the layer will be thin (with space to the next layer), but the material will have the'real' thickness.

Attention

The default thickness should be set thin enough that no touching or overlapping with the next layer can happen.

Returns

std::shared_ptr the Acts::CylinderVolumeBuilder which can be used to build the full tracking geometry

the dd4hep::DetElements of the layers of the negative volume

the dd4hep::DetElements of the layers of the central volume

the dd4hep::DetElements of the layers of the positive volume

the dd4hep::DetElements of the layers of the negative volume
