• Regarding the GAGG detector
  1. adjust the fitting of ¹⁵²Gd
  2. do a simultaneous fit to estimate the contamination values

• Next step
  1. test the time reconstruction of the DAQ using a pulse generator
  2. understand the 7 ms coincidence:
     1. look for coincidence analysis: ²¹¹Pb (beta/gamma) → ²¹¹Bi (alpha)
     2. do low background gamma spectrometry measurements and look for the low energy gamma rays
  3. take background data with a shorter time window and search for ²¹²Bi → ²¹²Po
  4. order a new GAGG wafer and try to operate it as a bolometer with a much better energy resolution to estimate the half-life of ¹⁵²Gd
  5. Be can be obtained for the (γ，n) reaction
