This is the signature used in most ATLAS clients.

Parameters

[in]	ctx	Event context
[in]	fieldCache	Magnetic field cache
[in]	Tp	Track parameter hypothesis used for road building. For example obtained from a seed. Will be used to populate a set of space points along the expected trajectory, and to search for detector elements along this linearised trajectory using the signature above
[in]	direction	Direction of propagation - either along (inside out) or against (cosmic) momentum.
[out]	Road	List to be populated with the elements of the search road. Will be sorted along the trajectory.
[in,out]	roadMakerData	event data object used to cache information during an event in a thread-safe way

500 MeV / pT

truncate at huge pt

step size - scaled by pt / 500 MeV

upper limit to step size: 1000 ;

get a list of global positions for the road search by starting from the first surface and walking along the trajectory using the RK propagator

should find at least 2 positions to sample

if we are extrapolating along them momentum direction, we pick out the part ascending in R

if the next point is at lower r than the previous point, remove the previous one

now perform the road building using our set of positions

detElementsRoad() [2/2]

void InDet::SiDetElementsRoadMaker_xk::detElementsRoad ( std::deque< Amg::Vector3D > & globalPositions, std::vector< const InDetDD::SiDetectorElement * > & Road, bool testDirection, SiDetElementRoadMakerData_xk & roadMakerData, const EventContext & ctx ) const

overridevirtual

This signature assumes you already have a list of positions along the trajectory.

It will look for detector elements compatible with being crossed by the linearised trajectory provided and fill those into the 'Road' argument. If 'testDirection' is used, we only fill detector elements encountered while traversing in the positive direction.

Parameters

[in]	globalPositions	set of points along the trajectory. Will linearise between them.
[out]	Road	vector to be populated with the elements of the search road. Will be sorted along the trajectory.
[in]	testDirection	If set, avoid adding detector elements encountered only when travelling in the negative direction. Set true for inside-out tracking, false for cosmic tracking.
[in,out]	roadMakerData	event data object used to cache information during an event in a thread-safe way

this is a vector of vectors of detector elements prepared by the SiDetElementsRoadCondAlg. The outer vector has 3 elements: 0 --> left endcap 1 --> barrel 2 --> right endcap Each of the inner vectors is internally sorted. For the endcaps, sorting is first in z, then for same Z in r, then for same r in phi. For the barrel, we first sort in R, then for same R in phi, then for same phi in Z.

iterators over the positions to consider

fill an array with the reference point (start with the first one), the road width and a placeholder for the step length

check the left endcap layers increment n0 until we are at the layer closest to the first position from the left side

check the barrel layers increment n1 until we are at the layer closest to the first position in the radial direction

and finally, the left endcap. this time, look for the layer closest on the right side.

reset the detector-element usage info. If we are the first client to see this event data object, we allocate the storage for all modules

if we are not the first client, we reset the event data without re-allocation

done with the first probed position. Now we can start to move along the trajectory

store the point we are aiming towards

x of the current position

y of the current position

z of the current position

r of the current position

perform linearisation

dx between the current and the first position

dy between the current and the first position

dz between the current and the first position

3D distance between the current and the first position

if geometry breaks down or two points are duplicates,

we whistle innocently and make a point of looking somewhere else

inverse distance to the first position

now we can book the linearised search direction

Having found the search direction, we are ready to look for detector elements and iterate. Before doing so, we add an additional test to ensure we probe the perigee point if we cross it on the way.

transverse component of the separation vector

negative component of the global location of the previous position into the direction connecting our positions in the x-y plane corresponds to the path length opposite to the linearised direction to reach the perigee

a positive value of SM means the closest approach to the beamline is between the two positions we are considering. In this case, we do not want to iterate to the next point, but instead insert an additional step where we use the perigee point as our reference. We do this by setting the target point to the perigee, which will be made the reference point when repeating the loop. Since the perigee is estimated using the linearised direction, this direction stays valid and does not need to be updated.

only add the perigee point if the next point is beyond the perigee, and if we are not too close anyway

now, the target point is the perigee estimate, while the reference point for this round stays unchanged.

allow 2cm on top of the perigee location when extrapolating inward.

Start collecting detector elements traversed by our linearised path.

First, barrel elements

if we are moving outwards in r:

loop over all barrel layers (starting with the closest one previously identified)

stop if we moved past the targer point in R

collect all compatible detector elements from the current layer

if we are moving inward in R, iterate the other way for the barrel

stop if we moved past the test point in R

collect all compatible detector elements

Positive endcap again check if we are moving forward or back in z

collect all compatible detector elements

collect all compatible detector elements

Negative endcap same game as above

collect all compatible detector elements

collect all compatible detector elements

update the starting point to be the current target point

and increment the total propagation distance
