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

2. Meeting with Keith  Better understanding of system requirements Emphasis on relative output Confirmed HK details to be measured ○ Temperature of LED is important  Ideas for LED temperature measurements Fiber couplers

3. GUI work

4. PIC work  Bare outline of code needs 0. Include libraries 1. Define variables used 2. Initialize pins (clear PORTA, PORTB, configure pins as inputs vs. outputs) 3. Actual code a. Take in measurements from the circuit (2x voltage for DC- DC current, 2x voltage for DC-DC voltage, 1 voltage for LED current, 1 voltage for LED voltage, temp. sensor input) b. Send measurements to USB connection c. Read user inputs from USB connection d. Output voltages corresponding to these user inputs  Researching USB to PIC connection Advice?

5. General circuit layout

6. Next steps  Create a detailed PERT chart based upon descriptions from Keith  Use specifics from Keith (LED datasheets, etc.) to ID components so that we can begin detailed designs Precision resistors to measure current with (current plan: measure voltage across resistor in series with component to determine current—other ideas?) Temperature measuring components Look into how to check that the x-ray output is correct (how MCA works—look at site (esp. intro information))
