| MOPTS082 | Status of ESS Linac Upgrade Studies for ESSnuSB | 1038 |
|

|
Funding: ESSnuSB has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 777419. The European Spallation Source (ESS), currently under construction in Lund, Sweden, is the world’s most powerful neutron spallation source, with an average power of 5 MW at 2.0 GeV. In the ESS neutrino Super Beam Project (ESSnuSB) it is proposed to utilise this powerful accelerator as a proton driver for a neutrino beam that will be sent to a large underground Cherenkov detector in Garpenberg, mid-Sweden. In this paper we discuss the required modifications of the ESS linac to reach an additional 5 MW beam power for neutrino production in parallel to the spallation neutron production. |

| MOPTS103 | First Results of Beam Commissioning on the ESS Site for the Ion Source and Low Energy Beam Transport | 1118 |
|
||
| The European Spallation Source (ESS), currently under construction in Lund, Sweden, will be a spallation neutron source driven by a proton linac of an unprecedented 5 MW beam power. Such a high power requires its ion source (IS) to produce proton beam pulses at 14 Hz with a high peak current more than 62.5 mA and a long plateau up to §I{3}{ms}. The IS and the following low energy beam transport (LEBT) section were manufactured and tested with beam to meet ESS requirements at INFN-LNS and delivered to ESS towards the end of 2017. Beam commissioning of these two sections on the ESS site has started in September 2018 and will continue until the end of June 2019. This paper provides an overview on this first beam commissioning period at ESS and also presents results of IS characterization and testing on LEBT functionalities. | ||

| TUPMP012 | Power Converters for the ESS Warm Magnets: Procurement Status | 1251 |
|
||
| In the frame of the Italian In-Kind collaboration for the construction of the European Spallation Source (ESS), Elettra Sincrotrone Trieste research center is in charge, among all, of the provision of the power converters for the warm magnets of the superconducting part of the linear accelerator and of the proton beam transport line. The procurement process is running for all types of power converters. The first components have been delivered to ESS already in March 2018, while the Dipole and Quadrupole power converters are under construction. The first batches have been factory tested and shipped to Lund. The corrector power converters have been manufactured and are currently tested and calibrated at Elettra before their delivery to ESS. | ||

| THPTS102 | Radio Frequency Power Stations for ESS LINAC Spoke Section | 4346 |
|
||
| 26 equivalent 400 kW Radio Frequency Power Station (RFPS) units will be provided by Elettra as part of the Italian in kind contribution to ESS. They will be installed in the LINAC "Spoke Section". Each RFPS will power a single superconducting spoke cavity in pulsed operation at 352.21 MHz. The RFPS is a complete system that operates unmanned, based on a combination of solid state and tetrode amplification’s stages. The tender specification, the RFPS main features and requested performances are reported here. | ||
