===== Targets =====
  * **MPPC properties**
    * observe 1pe, 2pe and the corresponding threshold 
    * check the rising/falling time (note the definition of the rising and falling time)
    * dark count rate with 1pe; 2pe; 3pe
    * check `pattern` trigger (need calibration?) with coincidence of 2, 3
      * Use DRS4 waveform generator (or Arduino) for example 
      * Coincidence gate 

  * **Fluorescence lifetime by exciting with UV LED** 
    * Measure rising/falling time with oscilloscope (note the signal size)
    * Fit with exponential and/or oscilloscope measurement function 

  * **Cosmic muon counter** 
    * calculate the rate with area of detector (size of plastic scintillator)
    * Scintillator inefficiency (rate of 1,2,4; vs rate of 1,2,3,4)
    * Muon Signal corresponding to how many P.E?

===== Hands-on Activities =====
1. Act#1 (1.5h, Feb. 27 AM): safety, lab arrangement, components, rules; light source (LED)  driven with waveform generator, arduino or analog discovery; various LED wavelength; soldering a circuit for LED (this is to use with MPPC later, so think a bit about design to easily coupling to MPPC (direct or with optical fibers, mimicking the use of the WLS))

2. Act #2 (1.75h, Feb. 27 PM) oscilloscope functionality, signal generation with analog discovery, counting function  and coincidence pattern trigger

3. Act #3 (2.75h, Feb. 28 AM): Single MPPC circuit; soldering, testing signal, pedestal; noise mitigation with Faraday case, checked if can see single P.E without amplifier? 

4.  Act #4 (2.75h, Feb. 28 PM): Start working with MPPC array; measure MPPC characteristics (noise rate, gain; timing response); measure the fluorescence lifetime with Thorlabs fluorescence plates

5.  Act #5 (2.75h, Mar. 1 AM): Continue with fluorescence lifetime measurement if needed. measure coincidence rate. Work in combination of Scintillator, wavelength shifting fiber and photosensor; concept of muon counter; NIM modules to use: discriminator, scaler, coincidence (and delay if needed)

6.  Act #6 (2.75h, Mar. 1 PM): Data taking and analysis

7.  Act #7 (2.75h, Mar. 2 PM): Data taking and analysis 

8. Act #8 (2.75h, Mar. 3 AM): Data taking and analysis

9.  Act #9 (2.75h, Mar. 3 PM): Data taking and analysis
