  The CERN PS in­jec­tion kicker has been mod­i­fied in the frame­work of the LHC In­jec­tor Up­grade (LIU) pro­ject to allow in­ject­ing pro­ton beams with an en­ergy of 2 GeV. One of the most im­por­tant items of the sys­tem pa­ra­me­ter val­i­da­tion is the mea­sure­ment and analy­sis of the mag­netic field in the mag­net aper­ture. To meet the re­quired mea­sure­ment pre­ci­sion with­out com­pro­mis­ing the mag­net vac­uum per­for­mance, a ded­i­cated mag­netic probe has been de­signed, con­structed and tested. The re­sults are pre­sented in this paper high­light­ing the mit­i­ga­tions of elec­tri­cal, me­chan­i­cal and vac­uum com­pli­ca­tions. The paper con­cludes with an analy­sis of the probe per­for­mance dur­ing the first mag­netic field mea­sure­ments in the lab­o­ra­tory.

  Within the frame­work of the LHC In­jec­tor Up­grade (LIU) pro­ject, the fea­si­bil­ity and de­sign of an up­grade of the ex­ist­ing CERN PS pro­ton in­jec­tion kicker sys­tem have been out­lined in pre­vi­ous pub­li­ca­tions al­ready. This paper de­scribes the ad­just­ments of final de­sign choices, test­ing, and de­ploy­ment as well as the val­i­da­tion and com­mis­sion­ing of the new 2 GeV in­jec­tion kicker sys­tem. The up­grade pays par­tic­u­lar at­ten­tion to the re­duc­tion of pulse re­flec­tions un­avoid­ably in­duced by a mag­net in short cir­cuit mode con­fig­u­ra­tion whilst keep­ing a fast 104 ns rise and fall time. An adapted thyra­tron trig­ger­ing sys­tem to re­duce jit­ter and en­hance thyra­tron life­time is out­lined. Ad­di­tion­ally, im­prove­ments to the mag­net entry box and the elim­i­na­tion of SF6 gas in the mag­net con­nec­tion box and the as­so­ci­ated pulse trans­mis­sion lines are dis­cussed.
