   * Need to polish
   * Need to consider how coupling with single/array MPPC (whether using an optical coupling or well-aligned laser cut). For MPPC, only one option is to use customized plate, but need to consider how to fix the position of wavelength into the plate. Remember the channel mapping for MPPC array
+    * Light tightening of the WLS
+    * Use UV glue

-===== Data acquisition  =====
+===== 5. Data acquisition  =====
   * Two oscilloscopes are available for two team. Team A can use 200MHz bandwidth oscilloscope while team B can use 100Mhz bandwidth. Four channels can be used
+===== 6. LED and driving methods =====
+  * LED with different wavelength are available
+  * To drive LED, specifically for pulsing ~ 100ns
+    * Use Function generator
+    * Use Analog Discovery
+    * Use Arduino (UNO (~100ns) or DUE (~24ns))
+  * Consider to coupling LED to MPPC: directly or via the optical fiber
+  * White LED, part number OSPW511A-Z3 [[https://akizukidenshi.com/goodsaffix/OSPW5111A-Z3.pdf]]; voltage applied 0-3.4V
