Abstract Title: Pulsed NMR (Nuclear Magnetic Resonance) A
Abstract: To facilitate real comfort with both the physics and the apparatus, we have limited the sessions to groups of 3, and created double sessions.  We strongly recommend that you sign up for both A and B sessions.

Nuclear magnetic resonance is a tool that allows the interaction of external radio-frequency magnetic fields with the magnetic moments of the nuclei found in ordinary liquids and solids.  In this workshop offering, participants will work on TeachSpin's new PS2-a, a tabletop, permanent-magnet, pulsed-NMR system that will display all the basic features used in modern pulsed-NMR technology.

Participants will see, at level A, Introduction to pulsed NMR:
  • a working PS2-a unit, configured for pulsed (rather than cw) operation on proton (rather than 19F) nuclei
  • familiarization with the permanent magnet and its temperature stabilization, and the sample-holder and its 'tuning' for optimal operation
  • installation of a sample, and detection of the pulsed-NMR signal, and its optimization by electronic gradient cancellation
  • measurement of the nuclear resonant frequency, and the inference of the magnetic-field strength, to 6-digit precision
  • variation of the signal with pulsed-rf amplitude and duration, and an interpretation in terms of rotation of a spin vector on the Bloch sphere
