Detailed Description

template <typename T ,
size_t N =3>
class allpix::DetectorField;

Field instance of a detector.

Contains the a pointer to the field data along with the field sizes, binning and potential field distortions such as scaling or offset parameters.

Public Functions Documentation

function DetectorField

DetectorField() =default

Constructs a detector field.

function isValid

inline bool isValid() const

Check if the field is valid and either a field grid or a field function is configured.

Return: Boolean indicating field validity

function getType

inline FieldType getType() const

Return the type of field.

Return: The type of the field

Note: The type of the field is set depending on the function used to apply it

function get

T get(
    const ROOT::Math::XYZPoint & local_pos,
    const bool extrapolate_z =false
) const

Get the field value in the sensor at a position provided in local coordinates.

Parameters:

• local_pos Position in the local frame
• extrapolate_z Extrapolate the field along z when outside the defined region

Return: Value(s) of the field at the queried point

function getRelativeTo

T getRelativeTo(
    const ROOT::Math::XYZPoint & local_pos,
    const ROOT::Math::XYPoint & reference,
    const bool extrapolate_z =false
) const

Get the value of the field at a position provided in local coordinates with respect to the reference.

Parameters:

• local_pos Position in the local frame
• reference Reference position to calculate the field for, x and y coordinate only
• extrapolate_z Extrapolate the field along z when outside the defined region

Return: Value(s) of the field assigned to the reference pixel at the queried point

function setGrid

void setGrid(
    std::shared_ptr< std::vector< double >> field,
    std::array< size_t, 3 > bins,
    std::array< double, 3 > size,
    FieldMapping mapping,
    std::array< double, 2 > scales,
    std::array< double, 2 > offset,
    std::pair< double, double > thickness_domain
)

Set the field in the detector using a grid.

Parameters:

• field Flat array of the field
• bins The bins of the flat field array
• size Physical extent of the field
• mapping Specification of the mapping of the field onto the pixel plane
• scales Scaling factors for the field size, given in fractions of the field size in x and y
• offset Offset of the field from the pixel center, given in fractions of the field size in x and y
• thickness_domain Domain in local coordinates in the thickness direction where the field holds

function setFunction

void setFunction(
    FieldFunction< T > function,
    std::pair< double, double > thickness_domain,
    FieldType type =FieldType::CUSTOM
)

Set the field in the detector using a function.

Parameters:

• function Function used to calculate the field
• type Type of the field function used
• thickness_domain Domain in local coordinates in the thickness direction where the field holds
