  The Drift Tube Linac (DTL) of the Eu­ro­pean Spal­la­tion Source (ESS) is de­signed to op­er­ate at 352.2MHz with a duty cycle of 4% (3 ms pulse length, 14 Hz rep­e­ti­tion pe­riod) and will ac­cel­er­ate a pro­ton beam of 62.5mA pulse peak cur­rent from 3.62 to 90 MeV. This paper gives a de­tailed overview of the ESS-DTL cur­rent me­chan­i­cal de­sign, and the re­lated dri­ving cri­te­ria. It pre­sents also an out­look of the main as­pects of the as­sem­bly and in­stal­la­tion, with re­lated equip­ments, tool­ings and pro­ce­dures.

  The Eu­ro­pean Spal­la­tion Source (ESS) uses a lin­ear ac­cel­er­a­tor to de­liver the high in­ten­sity pro­ton beam to the tar­get sta­tion for pro­duc­ing in­tense beams of neu­trons. The av­er­age beam power is 5 MW with a peak beam power at the tar­get of 125 MW. The nor­mal con­duct­ing lin­ear ac­cel­er­a­tor (linac) op­er­at­ing at 352.21 MHz ac­cel­er­ates a pro­ton beam of 62.5 mA from 0.075 to 90 MeV. It con­sists of an ion source, Low En­ergy Beam Trans­port (LEBT), Radio Fre­quency Quadru­pole (RFQ), Medium En­ergy Beam Trans­port (MEBT), and Drift Tube Linac (DTL). The de­sign, con­struc­tion and test­ing of those struc­tures is done by Eu­ro­pean part­ner labs as an in-kind con­tri­bu­tion to the ESS pro­ject. This paper pre­sents the sta­tus and plans for the ESS nor­mal con­duct­ing linac.

  An alu­minum model of the ESS DTL tank 2 has been de­liv­ered to INFN-LNL in de­cem­ber 2017. The tank is 7.1 m long, equipped with mov­able tuners and mov­able post cou­plers. The pur­pose of this DTL model is to ver­ify the RF de­sign choices (in par­tic­u­lar on the first 2 tanks where the Post cou­pler dis­tri­b­u­tion is ir­reg­u­lar) as well as im­ple­ment and debug al­go­rithms and pro­ce­dure for sta­bi­liza­tion and tun­ing. The prepara­tory sim­u­la­tion work and the re­sults of mea­sure­ments cam­paign are here pre­sented.
