| TU2AA01 | Overview of ADS Projects in the World | 310 |
|
||
| Accelerator-driven subcritical systems (ADS) offer an advantageous option for the transmutation of nuclear waste. ADS employs high-intensity proton linear accelerators (linacs) to produce spallation neutrons for a subcritical reactor. Besides the challenges of any megawatt proton machine, ADS accelerator must operate with stringent reliability to avoid thermal stress in the reactor structures. Thus, ADS linacs have adopted a reliability-oriented design to satisfy the operation requirements. This work provides a review and the present status of the ADS linacs in the world. | ||

| TU2AA02 | SPIRAL2 Final Commissioning Results | 314 |
|
||
| The commissioning of SPIRAL2 was carried out in different steps and slots from 2014 to end 2021. In a first phase, the proton-deuteron and heavy ion sources, LEBT lines and RFQ were commissioned and validated with A/Q=1 up to 3 particles. The validation of the MEBT (between the RFQ and the linac, including the Single Bunch Selector), linac and HEBT lines (up to the beam dump and to the NFS experimental room) started on July 2019, when GANIL received the authorization to operate SPIRAL2. The linac tuning is now validated with H+, 4He2+ and D+ and nominal H+ and D+ beams were sent to NFS for physics experiments. The main results obtained during the commissioning stages and the strategy used by the commissioning team are presented. | ||

Status and Beam Commissioning of the RAON Superconducting Linac | |
|
||
| Installation of the low energy superconducting linac was completed by 2021 and first cool-down will be started soon followed by the beam commissioning. Status of the cool-down and the preparation of the beam commissioning will be presented and first result of the injector beam commissioing of the RAON heavy ion accelerator will be summarized. | ||

| 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. | ||
