===== Main goals =====
  * Learn how to make SiPM (in this case we use MPPC) work (soldering the electronic circuit for providing bias voltage and get out the signal )
  * Explore the properties of MPPC: dark noise; single-photon resolving capability 
  * Understand the functionality of amplifier, discriminator, coincidence, scaler (or counter)
    * Note the threshold, pulse width 
  * Learn how to use the oscilloscope, particularly the trigger, bandwidth ....

==== Measurement goals ====
  * MPPC properties: dark noise rate with trigger 0.5 p.e; 1.5 p.e; 2.5 p.e (compare with the specification). Note the difference in the temperature 
    * Measure the rising time and falling time of the MPPC pulse (before and after amplifier)
  * Measure the speed of light in the optical fibers
  * Measure the muon rate 
    * Is it consistent with what we expect? 
    * On average, a muon passing through will deposit how many photo-electrons. 

===== 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))
  * Try LED with breadboard (or soldering one)

2. Act #2 (1.75h, Feb. 27 PM) oscilloscope, signal generation (with NIM or function generation); MPPC (a SiPM type) circuit, 

3. Act #3 (2.75h, Feb. 28 AM): MPPC circuit; soldering, testing signal, pedestal; noise mitigation with Faraday case

4.  Act #4 (2.75h, Feb. 28 PM): Light tightening; MPPC characteristics (noise rate, gain, supply voltage dependence; timing response); measure the speed of light in the optical fibers if having time (concept of light detection and ranging or LiDAR in short); NIM modules to use: disciminator and scaler

5.  Act #5 (2.75h, Mar. 1 AM): 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
