1 Tagging in T(b) (I) Generated 1M events of e + Pb208 collisions at 10  40 GeV/n with 1 < Q2 < 20, 0.3 < y < 0.95, parameter settings tuned by Mark, genShd = 3 After applying a cut, x < 0.002, about 38% of events left Considered tagging using evaporation neutrons all neutrons

2 Tagging in T(b) (II) Same data sample as on page 1
Comparison of tagging statistics and effective energy increase for evaporation neutrons all neutrons all combinations of neutron, proton, deuteron, and  multiplicities true T(b) data

3 Tagging in T(b) (III) Same data sample as on page 1
Considered tagging using residual nucleus rigidity A of residual nucleus

4 Tagging in T(b) (IV) Same data sample as on page 1
Comparison of tagging statistics and effective energy increase for evaporation neutrons residual nucleus rigidity A of residual nucleus true T(b) data

5 Tagging in d1 (I) Generated 1M events of e + Pb208 collisions at 10  40 GeV/n with 1 < Q2 < 20, 0.01 < y < 0.95, parameter settings tuned by Mark, genShd = 1 After applying a cut, x > 0.002, about 43% of events left Considered tagging using evaporation neutrons all neutrons

6 Tagging in d1 (II) Same data sample as on page 5
Comparison of tagging statistics for evaporation neutrons all neutrons all combinations of neutron, proton, deuteron, and  multiplicities true d1 data

7 Tagging in d1 (III) Same data sample as on page 5
Considered tagging using residual nucleus rigidity A of residual nucleus

8 Tagging in d1 (IV) Same data sample as on page 5
Comparison of tagging statistics for evaporation neutrons residual nucleus rigidity A of residual nucleus true d1 data

9 To Do T(b) plots A combined with evaporation neutron multiplicity (in progress) ratio of T(b) to that of evaporation neutrons to the 10/3 power  d plots  same as for T(b) but with x > 0.02 cut using the second data sample  T(b) plots using simulation data for particles detected after the downstream ion quad triplet (in progress) evaporation neutron multiplicity total neutron multiplicity evaporation proton multiplicity total proton multiplicity A of residual nucleus rigidity of residual nucleus d plots using simulation data for particles detected after the downstream ion quad triplet same as for T(b) but with x > 0.02 cut using the second data sample
