It has previously been demonstrated that certain spatial harmonics of the dipolar and quadrupolar components of the RFQ voltage have stronger effects on the beam quality than others*. The study suggested that, during the tuning process to compensate for manufacturing errors, some harmonic contents (other than the first ones) should be minimized. The analysis presented in this paper looks at how we can predict the beam quality knowing the content of each voltage harmonics. We propose also a strategy to minimize the impacts of the voltage errors on the output beam phase space during the tuning phase.

| THPIK005 | RF Conditionning of the Spiral 2 CW RFQ | 4114 |
|
||
| The SPIRAL2 RFQ is designed to accelerate light and heavy ions with A/Q from 1 to 3 at 0.73 MeV/A. The nominal beam intensities are up to 5 mA CW for both proton and deuteron beams and up to 1 mA CW for heavier ions. The four-vane cavity is made with 5 1-meter long sections mechanically assembled, it works at 88 MHz and is powered up to 180 kW CW to achieve the nominal vane voltage of 113.7 kV for A/Q = 3 ions. This paper describes the RF conditioning of the RFQ at GANIL with the setting of its RF systems and cooling system used to tune the cavity resonance frequency. | ||
