* Regarding the GAGG detector 
    - writing paper, will add DC analysis, and contamination values
    - start the Be(γ, n) reaction, hopefully this Friday
    - thermal neutron Am-Be data processed
 
  * LaBr3 detector
    - data exposure doubled, around 25 days
    - choose a journal to publish the <sup>215</sup>Po half-life measurement 
    - measure the half-life of the <sup>215</sup>Po's mother nucleus, <sup>219</sup>Rn
    - systematic uncertainties need to be considered
      - consider a linear background model, instead of a flat one
      - adjust time binning
      - check the fit method, use least square fitting (For ROOT: try "IEL" fit option)
      - adjust the energy window 

  * Simulating Am-Be neutron spectrum
