************************************************************ 
Action items 
************************************************************ 
1) Document the procedure and requirements of gluing hybrids onto MS for Plan 
A at NTU - Yi/Han-Sheng 
2) Document the procedure and requirements of gluing hybrids onto MS for Plan 
B by AIDC. This is needed before new hybrid production - Yi/Han-Sheng 
3) Document on how/where the company would measure the surface flatness and 
being parallel between inner-outer sectors, before and after glueing hybrids 
and inner-outer sectors together - Yi/Han-Sheng
4) Look into checking radiation tolerance of cooling soft tubes in 
STAR/Taiwan - Flemming/Yi
4) Find out how the company would fix the hybrid and measure its flatness and 
thickness - Maowu/Jianing
5) UIC send a T-board and cable to NCKU to check if there is any conflict 
with the MS - Zhenyu 
6) Adding Felix to FST mailing list - Rahul/Zhenyu
7) Looking into alternative clustering algorithm to improve matching 
efficiency - Xu
8) Studying the tracking performance by varying the Z-locations of FST disks, 
and number of r/phi segments - Krishan/Daniel
9) Looking into FST simulation with Te-Chuan’s code/instruction - Shenghui
