2. Progress  Got MCA set up to detect x-rays  Couldn’t get it to work with our system Voltage output wasn’t sufficient with output directly from the DAC in our circuit  Added high-current output op-amp (OPA551)  looks like that was the issue; need to test more

3. Next steps  Priority: Get system working with MXS to produce x- rays ○ Test with op-amps Revise circuit (add op-amps, power for op- amps)  revise PCB  Other: Constantly updating HK General improvements in system performance (i.e.: frequency accuracy)
