Abstract
A practical design for a high‐pass birdcage resonator is presented. Precision seamless telescoping tubes were used for easy tuning of resonant frequency by adjusting the length of the coils. Three probes, of 4.4, 5.0, and 25.0 cm in diameter, respectively, were constructed and tested. An empirical formula is given that can be used to calculate the capacitance needed for a given frequency when the desired physical dimension and the number of elements of the coil are specified. A simple three‐step procedure is suggested for easy fabrication of resonators that are routinely tunable over tens of megahertz.
