Description

The proton linear accelerator (p-LINAC) is envisaged as the injector for the antiproton physics program at the FAIR facility in Darmstadt, Germany. The p-LINAC is designed to deliver a beam current of 70 mA at an energy of 68 MeV with a repetition rate of 4 Hz. The ion source has been developed in collaboration with CAE. The Ladder RFQ was designed by IAP Frankfurt, as were the normal-conducting coupled CH cavities (CCH). The construction was carried out by local industrial partners and has been completed for the Ladder RFQ as well as for the first CCH cavity.
The proton driver—together with the antiproton production chain at FAIR—has been postponed due to a re-prioritization within the FAIR project and is currently in a frozen state.
In this paper, we describe the ongoing and planned high-power RF tests of the Ladder RFQ and the CCH cavities. Furthermore, we present the status of the RF systems, including the clystrons and the modulator. The preparation and maintenance of the test setup will ensure a smooth transition when the p-LINAC project is resumed.
