Abstract

We recently created a snake depolarizing resonance using an rf solenoid magnet in a ring containing a nearly 100% Siberian snake. We found that the primary snake rf resonance also had two weaker synchrotron sidebands, which are second-order snake resonances; they were probably caused by the energy-dependent strength of the solenoid snake due to the Lorentz contraction of its longitudinal ∫Ḃdl. This was the first observation of an rf synchrotron-sideband depolarizing resonance in the presence of a nearly full Siberian snake.

Each helium refill of the superconducting snake solenoid required turning off and then resetting the solenoid current; a ±0.01A change in the 100.3 A snake current shifted the rf resonance frequency by about 230 Hz. Thus, in Fig. 2, for each refill, we shifted the frequencies of all data points to correct for the apparent change in the solenoid's current; the frequency correction is indicated by the horizontal bars in Fig. 2. We also deleted the final five data points taken after a Cooler Ring failure, which apparently shifted the resonance frequencies by more than 1 kHz. This extreme sensitivity could be eliminated by a superconducting solenoid capable of running in the persistent mode during refills.
