2. Finalized SOW  To design and implement a Mac-based controller and housekeeping measurement system for a modulated x-ray source. The controller should be capable of outputting two user-specified high voltages (0-3kV and 0-10kV) to the nearest 50-100 V, as well as a signal necessary to achieve a desired relative flux output from a UV LED. The housekeeping measurement system will constantly display relevant measurements—the current, voltage, and temperature of the LED as well as the current and voltage input to the two DC-DC converters—to the user.

4. Progress  Adding to GUI  PICs  PoE Lab 3 (USB to PIC communication)  Looked through code  Researching components  Current measurement  Temperature measurement  Digital to analog conversion

5. Next steps  Use specifics from Keith (LED datasheets, etc.) to ID components so that we can begin detailed designs  Really need to finalize sensor choices From there, we can understand the inputs/outputs for the PIC code  Hardware design
