  • Investigated non-linearity of peak sensing ADC due to issues arising in energy calibrations and efficiency measurements.
  • Modified existing calibration code to use non-linear regression to account for ADC.
  • Sourced material needed for CaGaS Phase II setup.
  • Calculated ADC dead time for live-time correction to efficiency measurement count rates and calculated dead time per experiment.
  • Designed holder for Gd foils needed for CaGaS Phase II experiment. To be 3D printed and tested for tolerances.

  • Printed both parts of the Gd foil holder for CaGaS Phase II.
    • Parts fit together more than adequately considering they're 3D printed and not machined.
    • M3 bolts threaded through first part of the holder.
    • M3 nuts press fitted into the second part of the holder.
  • Edited rebinning code for energy calibrations for data sets collected with ADC to account for changes in calibration code.
    • Energy calibration script now uses 2nd order polynomial regression to account for nonlinearity of ADC
    • The coefficients from the regression are passed to another script to rebin ADC data from channel to energy, preserving bin count, but bin width will increase as a function of energy.
  • Designed Gd2O3 powder holder for CaGaS Phase II.
    • Have spray on clear coat to seal plastic after printing is complete.
