Adiabatic partial Siberian snake turn-on with no beam depolarization

Abstract

energies of about 20 GeV. Fortunately, recent experiments [5][6][7][8] no polarization was lost. This supports the conjecture that a Siberian snake can be varying the snake either once, twice or ten times; we found with good precision that between about 0 and 25% at 370 MeV. We measured the beam polarization after with a superconducting solenoid; this combination allowed varying the snake strength strengths. The snake consisted of two rampable warm solenoid magnets in series a partial Siberian snake at 370 MeV, where the spin tune, 1/,, is 2% for all snake A recent experiment in the IUCF cooler ring studied the adiabatic turn-on of

Overcoming an intrinsic depolarizing resonance with a partial Siberian snake

“…The resonance crossing rate was 2:4 10 ÿ5 rad ÿ1 . Polarization was measured at G 12:5 during a 1 s flattop after the partial Siberian snake was ramped to zero [17].…”
