Class DescriptionBrChkvParameters() Constructor: DO NOT USE Use BrDetectorParams(Char_t, Char_t ) instead BrChkvParameters(Char_t *name, Char_t *title) : BrDetectorParamsBase(name, title) Standard constructor. the name should be that of the associated detector e.g. "C1" or "RICH" BrChkvParameters(Char_t *name, Char_t *title, Char_t *filename) : BrDetectorParamsBase(name, title, filename) Constructor which also reads parameters in from a configuration file the name should be that of the associated detector e.g. "C1" or "RICH" ~BrChkvParameters() Default destructor void SetDefaultParameters() Set a set of reasonable default parameters. This is mainly to ensure that the private members are initialized with values that do not give rise to any problems in the methods which uses these parameters; void SetASCIIParameters(Char_t *line) Interpret a line for DC params. Form is ParamName:value. Eg Eg fTwopar:.20 or fEff: 0.95 void MakeC1Map() C1 mapping
There are 32 (8 (x) * 4 (y))
The mapping is as follows :
Internal tube numbering and position
y/x 0 1 2 3 4 5 6 7
3 8 9 10 11 12 13 14 15
2 0 1 2 3 4 5 6 7
1 16 17 18 19 20 21 22 23
0 24 25 26 27 28 29 30 31
NB!!!!
When you give tubenumbers to the other methods they
should be from 1-32.
Each readout section is 2.5 inch * 2.5 inch
void MakeRICHMap() RICH mapping
There are 320 (20 (x) * 16 (y))
The mapping is as follows seen from the particle going from the
mirror towards the detector :
They are grouped in groups of 4 as this
.... 09-12
..... 69-72 37-40 05-08
..... 65-68 33-36 01-04
Note that 01-04 and 289-292 (lower corners) are not instrumented
Additional notes :
The mirror is spherical
-------
<- focal length = 150 cm
______________ (center mirror to center readout plane)
(the angle is 2*9 degrees)
(mirror and perpendicalr is 9 degrees)
Each pixel is 1.2 cm * 1.2 cm
BrVector3D GetTubePosition(Int_t tubeNo) const Returns the xy position of the tube with respect to C1 - the backplane RICH - the pixeldetector plane Int_t GetClosestTube(Double_t x, Double_t y) const NB: only valid for C1 !!!!!!!!!!!!! Return the tube number of the tube closest to the point (x, y) on C1 - the backplane RICH - the pixeldetector plane Int_t GetTubeWithDirection(Int_t tubeNo, Int_t x, Int_t y) const Returns the tube no which are sitting in the direction x, y from tubeNo For C1 we have the map (Do Print("m") to get a pic) y/x 0 1 2 3 4 5 6 7 3 9 10 11 12 13 14 15 16 2 1 2 3 4 5 6 7 8 1 17 18 19 20 21 22 23 24 0 25 26 27 28 29 30 31 32 ****************************************************** Watch it!!!! The internal fXArray, fYArray and fXYTube numbering is different!: ****************************************************** Internal tube numbering and position y/x 0 1 2 3 4 5 6 7 3 8 9 10 11 12 13 14 15 2 0 1 2 3 4 5 6 7 1 16 17 18 19 20 21 22 23 0 24 25 26 27 28 29 30 31 Bool_t TestRange(Int_t x, Int_t y) const Test if the index in the xy array is out of range If out of range return kFALSE else return kTRUE void Print(Option_t *option="") const The print method options : m - also print tube mapping d - print author/date/lastmodified etc. Inline Functions
