FOUR IMPORTANT RESULTS The RFQ behaves as expected and we can reproduce the transmission curve. The mechanics, RF and the dynamics design are validated The integrated chopper dynamics (premiere) works and the chopper rise/fall time is adequate The through-beam emittance is the same as the chopper-off emittance The through-beam can be matched to the DTL ( and soon the DTL will tell us how well) alessandra lombardi

1-RFQ TRANSMISSION LIU DAY – 11 th April 2014 RFQ Transmission vs. RF power for different pressure in the LEBT (neutralisation)

2-BEAM CHOPPING LIU DAY – 11 th April 2014

3-EMITTANCE OF THE THROUGH BEAM LIU DAY – 11 th April 2014 Emittance measured with chopper off (left) and with chopper on (right ) downstream the inline dump

4-MATCHING TO THE DTL LIU DAY – 11 th April % transmission. As predicted by the simulation codes (TraceWin and Travel)

IN SUMMARY What has been done The LEBT, RFQ, and chopper line have been commissioned in their final set-up. The model have been fine- tuned and are an excellent guide to commissioning endeavours. So far so good…. What needs to be done The final source needs to be installed (Jacques). The DTL, CCDTL, PIMS and transfer line need to be installed and commissioned. A reliability run is planned for 2016 The final source needs to be installed (Jacques). The DTL, CCDTL, PIMS and transfer line need to be installed and commissioned. A reliability run is planned for 2016 LIU DAY – 11 th April 2014
