Probe Test Results (Stated 90o pulse lengths are the best achieved during installation. To reduce risk of damage to the probes, facility users should use slightly lower RF nutation frequencies (i.e. longer 90o pulse lengths) where possible. Please discuss with the facility manager appropriate RF nutation frequencies for your experiments.)
