Dear all,

Please find the meeting minutes in the following and please let me know if I missed anything. 

News

- No news. 

Sensor

  - NDL: Li finished the preliminary test on the first batch of the sensor. The results are expected. 

             Yi will check the status of the second batch with NDL.

  - Hamamatsu: The updated purchase order just submitted yesterday (change the testing requirement from 40 mum to 60 mum). 

Mechanical structure 

  - 3D printing prototype will be finished next Monday. 

  - The design of the first "real" prototype will be finalized in these two days and the company will provide the quotation tomorrow (2/22). The production will be started soon. 

  - The SolidWorks files were successfully transformed into the GDML format. Te-Chuan will contact Jason for the next step. 

  - Need to arrange a meeting with Rahul for the limitation on the STAR structure.  

  

T-board, Hybrid

  - Jianing presented the connector selection, Nicomatic is preferred. Yi and Han-Sheng will check whether this can be fitted into the current mechanical structure and we need to get the comments/confirmation from Gerard. The decision should be made soon (next week). 

  - Jianing has modified the design of T-board with both connectors on the same side (old connector), and the size remains the same (no extra layer). 

  - Once the connector is decided, Jianing will update all the designs.  

Simulation

  - Te-Chuan just finished the analysis, and he will send out the detailed report later. Quick summary: the results with tighter cut on the hits requirement have better charge misidentification rate 1% vs 2% (with out hits requirement). But the momentum resolution and efficiency are about the same. 

  - Te-Chuan also finished the comparison between different configurations (only sTGC, 1 FST + sTGC, 2 FST + sTGC and 3 FST + sTGC). The efficiencies are similar, but the momentum resolution is much better in the 3 FST + sTGC. Detailed results will be presented in his report, too. 

  - Te-Chuan will also perform the Hijing simulations. 

Cheers,

Yi
