Abstract
The ALICE ERL is an energy recovery test facility based at Daresbury Laboratory. We present investigations of charge and transverse variations/oscillations in the ALICE trains (up to 1600 bunches, spacing 55.2ns, bunch charge up to 60pC), using turn-by-turn EMMA BPMs adjusted for bunch-by-bunch measurements*. A set-up was established which allows use of pickups immediately downstream of the DC Gun as well as in the Arcs. To analyse variations, a DFT was used. It was established that a previously observed prominent (~10%) 300kHz charge envelope variation is a feature of the Photoinjector Laser. A set of transverse variations at 300kHz and below that depended on steering was also observed in the Injection Line. Downstream of the Booster, it was discovered that the transverse spectra are different. Prevailing quite regular variations (in range of 50um) were observed around 100kHz, manifesting themselves in the horizontal plane, present in non-dispersive regions, and dependent on trajectory offset in the Booster. We discuss the results, and also present our plans to apply this technique to a new single bunch injector EBTF now under commissioning in Daresbury Laboratory.
