  Once con­structed, the Eu­ro­pean Spal­la­tion Source (ESS) will be a 5MW pulsed neu­tron source based on a 2 GeV pro­ton linac de­liv­er­ing 2.86 ms long pulses at a 14 Hz rep­e­ti­tion rate. This paper fo­cuses on the beam in­stru­men­ta­tion per­for­mance dur­ing the re­cent linac beam com­mis­sion­ing up to drift tube linac (DTL) tank 4 with 74 MeV out­put en­ergy. In­stru­men­ta­tion and mea­sure­ment re­sults will be pre­sented for beam pa­ra­me­ters such as cur­rent, po­si­tion, en­ergy, emit­tance and beam loss.

  The ESS BCM sys­tem is not only used for beam mea­sure­ment but it also plays an im­por­tant role for ma­chine pro­tec­tion par­tic­u­larly in the nor­mal-con­duct­ing part of the linac. Dur­ing the pre­vi­ous beam com­mis­sion­ings to the MEBT and DTL1 FCs and be­fore the cav­i­ties were fully con­di­tioned, RF break­downs and other types of dis­charges in the cav­i­ties had a major im­pact on beam avail­abil­ity due to the Fast ma­chine pro­tec­tion func­tions of the BCM. Fol­low­ing an in­ves­ti­ga­tion on the root cause of the beam trips, the con­fig­u­ra­tion of the ma­chine pro­tec­tion func­tions was mod­i­fied to im­prove beam avail­abil­ity in the more re­cent beam com­mis­sion­ing to the DTL4 FC. In ad­di­tion to this, some op­ti­miza­tions were made in the BCM sys­tem to im­prove beam mea­sure­ment, and a few more func­tions were added based on new re­quire­ments. This paper re­ports on these im­prove­ments and the re­sults ob­tained dur­ing the beam com­mis­sion­ing through the DTL4.
