Day 13

This morning Dr Hornak showed us the EPR MOUSE. The RF probe that we had measured last week was now inside the MOUSE device. There was one problem though, the RF probe was not level with the edge of the iron yoke and was jutting out 0.7 inches above the yoke. We decided that the best way to solve this issue would be to shave off 0.7 inches off the edge of the coils that were also in the yoke so the RF probe would fit. After coming up with this solution we started brainstorming applications and demonstrations for the EPR MOUSE that we could perform. After lunch Dr. Hornak showed us how to run the MOUSE. This procedure is very similar to the larger EPR machine except that we have to demagnetize the iron yoke each time after we run a spectra because the iron yoke gets partially magnetized. We ran some paint samples that contained paramagnetic species to ensure that we could see the signal with the MOUSE device. We also tested a piece of paper with toner ink, a barcode, and a 1 dollar bill (US currency contains magnetic ink which can be detected by the EPR MOUSE). After these tests Baron (an REU student), Celia (an RIT student), and I created plans for demonstrations that we could conduct using the EPR MOUSE and a painting, a barcode, and a dollar bill.
Here are images of the EPR MOUSE and the larger EPR machine:
