- 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.
- 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.
