E-counter widths, angles, positions
T-counter widths, angles, positions
Ray plots showing E and T counters - several regions
E-counter channels (1-767): energy and relative rates for 2.39 GeV, no angular distribution
E-counter channels (1-767): energy and relative rates for 2.39 GeV, with angular distribution
E-counter channels (1-767): energy and relative rates for 2.98 GeV (OLD VERSION)
Shifts in channel relative energy k/E0 with incident beam energy
Energy boundaries and widths of E counters 1-384 (all E0)
Energy boundaries of T counters
Correlation between T counter and E counter numbers
Plot of correlation between T counter and E counter numbers
Sample file of relative rates per tagger channel (E channel and T number)
Focal plane segmentation and rates
Plot of transition beween small (T1-19) and large (T20-61) T counters (PostScript) -- Solid lines are rays for 1% steps in k/E0; dashed lines are rays for k/E0 = .7861 and .7765
Odd-even effect in E-counter fine channels:
- 767 individual fine channels (PS plot)
- 383 Double fine channels (odd+even) (PS plot)
