Meeting minutes:

1. News: BNL approved funds to support FST. Contract with Fermilab SiDet for 
FST module assembly has been put into BNL system since last week. According 
to the SOW, we need to provide Fermilab drawings for FST modules, Silicon 
sensors, hybrids and holding frames by this Sunday Sep 15. 

2. DAQ: Tonko found 2 ARCII and at least 1 ARM are removed from the IST 
crates. 1 ARCII and 1 ARM are in the lab in Physics building. Gerard and 
Tonko will verify the status of the IST crates and readout boards next week. 
Gerard and Paul will try to see if the IST slow control still works. 
Prithwish and Yu will try to learn from them and provide assistance if 
needed. 

3. Shipping
Han-sheng/Yi: designed a box to ship FST modules. 

4. Mechanical structure: EASTON will make the prototype mechanical structure 
in October. AIDC will produce 10 prototype cooling tubes and joints in 
October, and 55 in December. AIDC has done initial hybrid gluing to 
mechanical structure by eye. The tolerance for Hybrid fabrication is 200 
microns, and mechanical structure 100 microns. 

5. Silicon sensors
Yi: Yi and Zhangbu visited NDL last week. The NDL staffs think they are able 
to produce Silicon sensors but will take some time (~8 months) to find the 
proper settings for implantation and polysilicon. A new NCKU Master student 
will work on this. 

6. Hybrid, T-board, and Inner signal cables
Qian: Nicomatics connectors for T-boards have arrived in China. The agency is 
checking with the vendor to see if there is any issue with these connectors. 

7. Simulation 
Te-chuan: still working on FST GEANT modeling for cooling tube, and will add 
APV chips and T-boards. He will report them next week. 
Krishan: waiting for Daniel to provide the updated tracking code so that he 
could study how efficiency depends on R.

Action items: 
1. Prithwish will bring the ARCII and ARM back to STAR, and check exactly how 
many ARMs are removed from the IST crates, and will try to look for the other 
missing ARCII.
2. Flemming will find out from Rahul whether NOVEC has been delivered and if 
so contact Gerrit for having a look at the IST rack.
3. Han-sheng will add 2 more screws to fix the FST module in the box, and 
send Zhenyu the updated drawings and movie this Friday or Saturday. 
4. We will check if we can use the PELICAN boxes which were used for shipping 
IST modules for FST modules. Flemming found three of them at BNL.
5. Yi is working on the documentation of the mechanical structure. He has the 
inputs from EASTON and AIDC in Chinese and will convert them to English. 
6. Yi will discuss with AIDC for the precision they can achieve and whether 
or not specific fixtures are needed for mounting hybrids to mechanical 
structure 
7. There are a number of studies to study the number of segmentation and 
Z-locations that should be done once the tracking code is ready.
