1. Gwynneth Davidoff, Kendall Pletcher, Mary Schmidt, Amy Whitcombe

2. Progress  Constant updating on GUI is working!  More tests with PCB—seems to behave as expected  Emailed Keith, asked for feedback Suggested we make sure that the photodiode isn’t seeing the UV output instead of x-rays  Have a heat sink to try

3. Improvements  Add larger ADC for voltage measurements  Improve PWM implementation for speed  Compensate for nonlinearity of voltage-flux response of LED

4. Next steps  Finish up with revised version of PCB  Make sure that readings from MCA are x-rays, not UV  Test new ADC, implement improvements  Improve write-up
