  The High Lu­mi­nos­ity Large Hadron Col­lider (HL-LHC) pro­ject will up­grade the LHC ma­chine to allow op­er­a­tion with in­creased lu­mi­nos­ity for the ex­per­i­ments. In order to achieve this goal, dif­fer­ent op­er­a­tional pa­ra­me­ters of the ma­chine need to be pushed be­yond the pre­sent de­sign val­ues, in­clud­ing the stored beam en­ergy. One of the main chal­lenges re­lated to the achieve­ment of the up­graded per­for­mance is the beam col­li­ma­tion sys­tem and its con­tri­bu­tion to the over­all ma­chine im­ped­ance bud­get. In this per­spec­tive, new low im­ped­ance col­li­ma­tors have been de­signed, fab­ri­cated, and in­stalled in the LHC. In this study, we will pre­sent their de­tailed elec­tro­mag­netic (EM) char­ac­ter­i­za­tion by means of radio fre­quency (RF) mea­sure­ments and EM sim­u­la­tions.
