•  numbering of layer/ladder of upgr15

I used a .fzd file and ran the macro from Gerrit that dumps the hits positions.

I printed the volumeId from g2t_pixl_Hit.

The previous decoding (for upgr13 for example) used the following logic :

($STAR/StRoot/StmcEvent/StMcPixlHit.cc)

00099 StMcPixelHit::ladder() const
00100 {
00101   // 3 modules of 11 ladders each; 8 outer and 3 inner ladder per module
00102   // layer 1 : ladder 1 -  9
00103   // layer 2 : ladder 1 - 24
00104   unsigned long iModule = mVolumeId/1000000;
00105   unsigned long iLadder = (mVolumeId%1000000)/10000;
00106   //cout<<"volume id: "<<mVolumeId<<endl;
00107   //cout<<"iModule: "<<iModule<<endl;
00108   //cout<<"iLadder: "<<iLadder<<endl;
00109   if (iLadder>3) // outer: 3*(4-11) to 1-24
00110     {
00111       iLadder=(iModule-1)*8+iLadder-3;
00112     }
00113   else
00114     {
00115       iLadder = (iModule-1)*3 + (iLadder);
00116     }
00117   //cout<<"final iLadder: "<<iLadder<<endl;
00118   return iLadder;
00119 }

So with upgr15, we have 2layers with respectively 10 and 30 ladders.

Following the same idea, I printed :

mVolumeId/1000000 and (mVolumeId%10000000)/10000 ;

========> PIX: x y z = 2.50096 0.708255 -0.012885 volumeId  1100000 Module :1 ladder :10
========> PIX: x y z = 2.50072 0.211995 -2.43057 volumeId  1100000 Module :1 ladder :10
========> PIX: x y z = 2.50096 -0.708215 0.183455 volumeId  1100000 Module :1 ladder :10
========> PIX: x y z = 2.50064 -0.478055 -2.90135 volumeId  1100000 Module :1 ladder :10
========> PIX: x y z = 2.50085 0.456895 -1.45369 volumeId  1100000 Module :1 ladder :10
========> PIX: x y z = 7.83954 1.60039 2.10441 volumeId  2010000 Module :2 ladder :1
========> PIX: x y z = 7.85758 1.51472 -5.97336 volumeId  2010000 Module :2 ladder :1
========> PIX: x y z = 7.92052 1.21953 -0.553725 volumeId  2010000 Module :2 ladder :1
========> PIX: x y z = 7.77794 1.88948 5.72732 volumeId  2010000 Module :2 ladder :1

 

So we have

• 1 <= volumeId/1000000 <=2
• 1<=(volumeId%1000000)/10000 <=10 for volumeId/1000000 ==1
• 1<=(volumeId%1000000)/10000 <=30 for volumeId/1000000 ==2

So we can identify layer == volumeId/1000000 and ladder == (volumeId%1000000)/10000

In the macro, I used those condition

Fig 1 : X vs Y global positions of hits when requiring volumeId/1000000 ==1

Fig 2 : X vs Y global positions of hits when requiring volumeId/1000000 ==2

• I did the same for IST ; with the same .fzd file , I printed and filled in a tuple :

 

tuple2[8]  = vol/1000000;

tuple2[9]  =(vol%1000000)/10000;

So it appears that vol/1000000 returns the ladder_id : 1< vol/1000000 < 25

and (vol%1000000)/10000 returns the wafer_id : 1 <(vol%10000000)/10000< 12

Here is the output of the macro where I printed the position of hits and the 2 last columns are vol/1000000 and (vol%1000000)/10000

• Reason why only the first layer is built

From starsim, I represented the path of the volumes created with pixlgeo00.g

The path should be :

/HALL_1/CAVE_1/PXMO_1/PXLA_1/PLMI_1-10/PLAC_1 for the inner layer

/HALL_1/CAVE_1/PXMO_1/PXLA_2/PLMI_1-30/PLAC_1 for the outer layer 

So the first layer is correctly built (PXLA extension) but the second has PXL1 extension
