Hey Careina I had once experience the same phenomenon. No diffraction at all. That did not make any sense to me. So i dipped the "empty" loop in the water, and flash froze the loop in liquid nitrogen. Once exposed to X-ray, there was no ice rings... Eventually, it turned out that system had a glitch, and there was no X-ray. True story!
