| TU2AA04 | Commissioning of IFMIF Prototype Accelerator Towards CW Operation | 319 |
|
||
| Construction and validation of the Linear IFMIF Prototype Accelerator (LIPAc) have been conducted under the framework of the IFMIF/EVEDA project. The LIPAc consists, in its final configuration, of a 100 keV injector and the world longest 5 MeV RFQ accelerator, followed by a MEBT with high space charged and beam loaded re-buncher cavities, an HWR-SRF linac, HEBT with a Diagnostic Plate, ending in a Beam Dump (BD) designed to stop the world highest deuteron current of 125 mA CW at 9 MeV. The beam commissioning at a low duty cycle of ~0.1 % led to a successful RFQ acceleration of 125 mA and 5 MeV beam in 2019. The following beam commissioning phase was initiated in July 2021 with a temporary transport line replacing the SRF linac. The major goals of this phase are to validate the RFQ, MEBT and BD performances up to CW and to characterize the beam properties in preparation to the final configuration with the SRF linac. This paper will present progresses made in this phase so far, such as a low-current and low-duty beam commissioning completed in Dec. 2021, CW operation campaign of the injector towards the nominal beam current, and RF conditioning of the RFQ towards CW. | ||

| TUPOJO09 | High Power RF Conditioning of the ESS DTL1 | 356 |
|
||
| The first tank of Drift Tube Linac (DTL) for the European Spallation Source ERIC (ESS), delivered by INFN, has been installed in the ESS tunnel in Summer 2021. The DTL-1 is designed to accelerate a 62.5 mA proton beam from 3.62 MeV up to 21 MeV. It consists of 61 accelerating gaps, alternate with 60 drift tubes equipped with Permanent Magnet Quadrupole (PMQ) in a FODO lattice. The remaining drift tubes are equipped with dipole correctors (steerers), beam position monitors (BPMs) or empty. The total length of the cavity is 7.6 m and it is stabilized by post couplers. Two waveguide couplers feed the DTL with the 2.2 MW of RF power required for beam operation, equally divided by RF power losses and beam power. This paper first presents the main systems required for the DTL conditioning. Then it summarizes the main steps and results of this high power RF conditioning done at ESS to prepare the DTL for the consequent beam commissioning. | ||
