Direct Known Subclasses:

BarHit

public class ATOFHit
extends Object

Represents a hit in the atof. Stores info about the sector, layer, component, order, TDC, ToT. Type is wedge/bar up/bar down/ bar Spatial coordinates are computed from atof detector object using the geometry service Stores whether the hit is part of a cluster. Calculates time, energy based on TDC/ToT.

Constructor Details

ATOFHit

public ATOFHit(int sector,
 int layer,
 int component,
 int order,
 int tdc,
 int tot,
 Detector atof)

Constructor for a hit in the atof. Initializes the hit's sector, layer, component, order, TDC, ToT. Sets the hit's initial state regarding clustering. Set up the hit's type, time, energy, and spatial coordinates.

Parameters:

sector - The sector of the detector where the hit occurred.

layer - The layer of the detector where the hit was detected.

component - The component within the layer that registered the hit.

order - Order of the hit.

tdc - TDC value.

tot - ToT value.

atof - Detector object representing the atof, used to calculate spatial coordinates.

setIdTDC

public void setIdTDC(int index)

computeModuleIndex

public int computeModuleIndex()

Computes the module index for the hit.

makeType

public final String makeType()

Assigns a type to the hit.

convertTdcToTime

public final int convertTdcToTime()

Converts TDC to time (ns). Sets the hit time parameter to a raw time for up/down bar hits or to the time corrected for the propagation for wedge hits.

Returns:

0 if the time was successfully set, or 1 if the hit type is unsupported.

convertTotToEnergy

public final int convertTotToEnergy()

Converts ToT to energy (MeV). Sets the hit energy parameter to a raw energy for up/down bar hits or to the energy corrected for the attenuation for wedge hits.

Returns:

0 if the energy was successfully set, or 1 if the hit type is unsupported.

convertSLCToXYZ

public final int convertSLCToXYZ(Detector atof)

Calculates spatial coordinates for the hit based on associated detector component. Retrieves the midpoint of the atof component to assign the corresponding x, y, z coordinates to the hit (mm).

Parameters:

atof - The Detector object representing the atof.

Returns:

0 if the coordinates were successfully set, or 1 if the hit type is undefined or unsupported.

matchBar

public boolean matchBar(ATOFHit hit2match)

Compares two ATOFHit objects to check if they match in the bar.

• If the sector or layer of the two hits do not match, the method returns false.
• If either hit is not in the bar (component must be 10), the method returns false.
• If both hits are in the same SiPM (i.e., their order is the same), or have incorrect order, the method returns false.

If none of these conditions are violated, the method returns true, indicating the two hits match.

Parameters:

hit2match - The ATOFHit object to compare with the current instance.

Returns:

true if the hits match; false otherwise.

getPhi

public double getPhi()

Computes the azimuthal angle (phi) of the hit in rad.

Returns:

The azimuthal angle (phi) in radians, in the range [-π, π].

main

public static void main(String[] args)

Parameters:

args - the command line arguments
