  The instablility of the China ADS SC section of the injector-I testing facility is investigated. The performance of the beam footprinted at different positions of the instability chart are studies using program and compared with experiment results. A moderate design was chosen to avoid envelope resonances or equipartitioning between different freedom of planes. The longitudinal acceptance is determined by the stabilization of the cavity phase and amplitude. The details will be reported in this presentation.

  As a test facility, the design goal of C-ADS Injector I is a 10mA, 10MeV CW proton linac, which uses a 3.2MeV normal conducting RFQ and superconducting single-spoke cavities for accelerating. The RF frequency of C-ADS Injector I accelerator is 325 MHz. In accordance to the progress of construction and considering the technical difficulties, the beam commissioning of C-ADS Injector I is carried out in 3 phases: Phase 1, with ECRIS + LEBT + RFQ + MEBT + TCM (two superconducting cavities), to reach 3.6 MeV; Phase 2, with ECRIS + LEBT + RFQ + MEBT + CM1 (seven superconducting cavities), to reach 5 MeV; Phase 3, with ECRIS + LEBT + RFQ + MEBT + CM1+ CM2 (same as CM1), to finally achieve the design goal of C-ADS Injector I. This paper summarizes the beam commissioning in 3 phases and focusing on the third phase.
