Positions of pads
connected to electronic channels
in all strings and FECs used in Test Beam '98

Go to FEC0 chip positions
Go to FEC1 chip positions
Go to FEC8 chip positions
Go to FEC9 chip positions

    Sometimes it is usefull to know what are the positions in space of pads connected to a particular channel. This information is neccessary to look for effects in raw signal processing associated with a particular geometrical configuration of the apparatus.

    Below, there are four pictures showing positions of pads connected to particular chips for FECs 0,1,8,9 and strings 0,1,2,3 used in the Test Beam '98 experiment. Chip numbers are color labeled on these pictures. Chip 0 is seen in red color, chip 1 as green, and so on up to chip no 5 colored blue.
    Unfortunately also positions in Z direction change for a single FEC value. Assignement between FEC/String nos and plane name is the following:
   

FEC=0 FEC=1 FEC=8 FEC=9
String=0 NA00 NC00 NA01 NC01
String=1 NA01 NC01 NA00 NC00
String=2 NB00 ND00 NB01 ND01
String=3 NB01 ND01 NB00 ND00
