Status update:

1) Working on pion asymmetry
2) Supporting Columb Sum Rule
3) Target ladder information to Rob

1) Pion Asymmetry
Using the following cuts:

i) PID: energy between 125 and 425 
ii) position: cut on vertex Z (beam direction) +/- 18cm (target = +/- 20cm)
iii) T2s only 
Got a very small number of events: for asymmetry of 0.97%, got an uncertainty of 1.51%

iv) Per Rob, added in random T3s, now uncertianty is closer to 0.64%

However, do not get consistent results:

run    A
4490    3.685% ± 0.638%
4494    1.405% ± 0.641%
4585    0.264% ± 0.693%  

Need to do many runs and look at consistency (maybe there is something wierd abiout these 3 runs).  Would particularly like to look at one day and compare to NMR results. Have already checked that cuts are consistently ok across runs.

2) Supporting CSR: mostly weekends, but some weekdays, polishing (and soon testing) NaI blocks.

3) Target Ladder information;
i) see file "target_ladder.pdf"
ii) material for lader is Macor (see http://en.wikipedia.org/wiki/Macor), with a density of 2.52 g/cm^3
iii) material for gusset is High temp mica, density 2.77cm^3
iv) protons from each position (e.g. polarized target, foils, empty) pass thorugh different material
v) protons from *foils* passes through ladder and gussets 


Moving forward (for next meeting):

1) finish pion asymmetry
2) continue helping CSR
3) \kappa_0 measurement plan (p.s. Todd's student pass qual. and he(Todd) hired a new tech.)
4) DNP talk
