Procedure and table of results

We calculate
S1 - 1st short side of 2x1
S2 - 2nd short side of 2x1
L1 - 1st long side of 2x1
L2 - 2nd long side of 2x1

dS and dL are the deviations of the 1st and 2nd corner along the short and long sides, respectively. The sign of all dS are chosen in order to provide correct sign for the tilt angle (the same direction for all 2x1 sensors).

Everything, excluding <dS/L> and angle(deg), are in micrometers.

  • All ds1, dl1 are well consistent (within +/-10um) with ds1, dl1, respectively
  • Angles of 2x1 are in the range from -0.39 to +0.33 degree.

Quads' alignment

Relative quads' alignment is preliminary done based on cxi80410-r1150, based on DSD image averaged over 1000 events,

where the shadow of mechanical parts can be destinguished. In order to lign-up the boarders of this shadow we apply constants:
marg_gap_shift/0-end.data

15  40   0  24

 0   0   0   0

offset_corr/0-end.data

 1 -3  0  1
 1  1 -1 -1
 0  0  0  0

This image still have two degrees of freedom: X- and Y- gap between quads. Currently we set in marg_gap_shift/0-end.data both gaps to zero.

All other parameters have their nominal values:
