For our lab before the most recent one, we tried to troubleshoot our set up since we were not obtaining any signal on the oscilloscope once the coil had been connected to the T/R switch, radio, and the various amplifiers … Continue reading → Continue reading
1) Quantify uniformity of Bz from a Maxwell Coil for a 20x20x20 mm cube and for a 10x10x10 mm cube. To quantify uniformity of Gz from a Maxwell Coil, we ran the MATLAB function simMaxwellCoil. This function plots the magnetic field … Continue reading → Continue reading
The past two weeks contained a series of victories, as well as a minor setback. During the first week, we connected the Rx port to the oscilloscope and the probe to the coil. We noticed that as the amplitude increased, … Continue reading → Continue reading
There were two independent labs that were done over the course of the past three weeks. The objective of the first lab was to test our surface coils to see if it actually produced a decent image. We hooked our … Continue reading → Continue reading
