Target lab status:
- Report by Vince, click here
- Report by Patricia:
1) Cell Temperature Study:
- improving codes
- studying the errors
- then will write a note
2) Lifetime Study:
- improving codes
- check equation
- then will finish to write the note
--> Plan:
- EPR: RF effect on the resonance frequency
- Optical lines: do realignment before testing new cell
- Optics: will spend more time on it.
- Report by Alexandre:
- produced the 1st ice-cone sol-gel at UVA
- has to push for diagnostic on the bad cells
Target/g2n analysis:(Kevin)
1) Last week, beam trip cut shows a disagreement: the large difference is gone now after choosing the good beam polarization.
--> will use beam trip cut: min current 8uA
2) Using Polrad2.0 for internal radiative correction
GDH analysis:(Karl)
1) includes external correction in qfs: good results for only one energy for unpolarized 3He cross section
2) checked his code against Elastic E-P scattering data from Mo&Tsai review article.

- Report by Vince, click here
Target/g2n analysis:(Kevin)
1) new replay:
- database optimized by Xiaochao and Nilanga
- changed geometry cuts
- shower cut
- deadtime correction
- beam trip cut
---> biggest change in Apar
2) solved the problem of offset in flux.

Target lab status:
- Report by Patricia,
1) Tested Vanilla: lifetime about 3 hours, max. polarization less than 15%
2) Created web Page for shift help
3) Learning Optics
4) Preparing for Thesis Progress Report.
Target/g2n analysis:(Kevin)
1) finished all the replays but hasn't looked at the data yet
2) worked on the error analysis of water calibration
A1n analysis:(Xiaochao)
1) elastic analysis with the new beam energy data
2) has to apply external radiative corrections.
