Detailed Description

Subdetector class for a single drift chamber with several planes.

This class will be created by the THcDC class which will also create the plane objects.

The THcDC class will then pass this class a list of the planes.

◆ CorrectHitTimes()

void THcDriftChamber::CorrectHitTimes ( void )

virtual

Use the rough hit positions in the chambers to correct the drift time for hits in the space points.

Assume all wires for a plane are read out on the same side (l/r or t/b). If the wire is closer to horizontal, read out left/right. If nearer vertical, assume top/bottom. (Note, this is not always true for the SOS u and v planes. They have 1 card each on the side, but the overall time offset per card will cancel much of the error caused by this. The alternative is to check by card, rather than by plane and this is harder.

protected

Simplified HMS find_space_point routing. It is given all y hits and checks to see if all x-like hits are close enough together to make a space point.

This is used for the old style HMS drift chambers, so is not used for any data since the new HMS chambers were installed before the Fall 2017 run.

◆ FindEasySpacePoint_SOS()

Int_t THcDriftChamber::FindEasySpacePoint_SOS	(	Int_t	xplane_hitind,

	)

protected

Simplified SOS find_space_point routing. It is given all x hits and checks to see if all y-like hits are close enough together to make a space point.

This is used for the SHMS and HMS (since Fall 2017) drift chambers which are of the same style as the old SOS chambers (XUV).

Int_t THcDriftChamber::FindHardSpacePoints ( void )

protected

◆ FindSpacePoints()

Int_t THcDriftChamber::FindSpacePoints ( void )

virtual

First check if number of hits is between fMinHits=min_hit and fMaxHits=max_pr_hits if fails then fNSpacePoints=0
Determines if it is an easy spacepoint.
1. if HMS style chambers finds the Y and Y' planes if not HMS style chambers finds the X and X' planes
2. if both planes ahve only one hit and the difference in hit position between the hits < fSpacePointCriterion and less than 6 hits . then easy spacepoint and calls either method FindEasySpacePoint_HMS or FindEasySpacePoint_SOS
3. FindEasySpacePoint_SOS
  1. Loops through hits and gets y_pos from the non-X planes and determines average Yt
  2. Loops through hits and sees if any of "Y-planes" hits has difference of y_pos -Yt > TMath::Sqrt(fSpacePointCriterion/2.0)
  3. Adds a spacepoint and set ncombos to zero.
if not EasySpacePoint calls FindHardSpacePoints
1. loops though hits and determines pairs of hits in planes with angles grerater then 17.5 degs between them. These are test pairs and stores the x and y position of pair
1. Double loops through the test pairs to determine number of pair combinations.
  1. Calculates d2 = (xi -xj)^2 + (yi-yj)^2 from the two pairs (i,j).
  2. If d2 < fSpacePointCriterion then fills combos structure with pair info and increments ncombos. c. Loop through ncombos
  1. First combo is set as spacepoint which is loaded with hit info from combos.
  2. Next combo
    1. Loops through previous space points
    2. calculates d2 = (x_c -x_sp)^2 + (y_c-y_sp)^2 between combos and spacepoint if d2 < fSpacePointCriterion then adds combos hit info to that spacepoint which is not already in the spacepoint.
    3. if that combo is not already added to existing spacepoint then new spacepoint is made from the combo.
If it found a spacepoint
1. For HMS-style chamber it would DestroyPoorSpacePoints if fRemove_Sppt_If_One_YPlane
2. Presently if HMS-style chamber calls SpacePointMultiWire()
3. Calls ChooseSingleHit this looks to see if two hits in the same plane. If two hits then rejects on with longer drift time.
4. calls SelectSpacePoints. Goes through the spacepoints and eliminates spacepoints that do not have nhits > min_hits and ncombos> min_combos ( exception for easyspacepoint)

The requirements for cloning are: 1) at least 4 planes fire, and 2) no more than 6 planes have multiple hits.
