  The APS-Up­grade pre­sents sev­eral chal­leng­ing de­mands to the booster syn­chro­tron. Swap-out in­jec­tion re­quires the booster to cap­ture a high charge bunch (up to 17 nC), ac­cel­er­ate it to 6 GeV, and main­tain a low emit­tance at ex­trac­tion for in­jec­tion into the stor­age ring. To ac­com­mo­date these con­flict­ing de­mands, the RF fre­quency will be ramped be­tween in­jec­tion and ex­trac­tion. How­ever, the RF cav­ity tuners will re­main sta­tic, which means the cou­plers will need to with­stand a high re­flected power at ex­trac­tion. This paper pre­sents a plan for a sys­tem that will meet the re­quire­ments for in­jec­tion ef­fi­ciency, ex­tracted emit­tance, and equiv­a­lent power at the cou­pler. Re­sults from track­ing sim­u­la­tions and beam stud­ies with a fre­quency ramp will also be shown.

A beam size mon­i­tor pro­vides an in­tu­itive dis­play of the sta­tus of the beam pro­file and mo­tion in an ac­cel­er­a­tor. In the pre­sent work, we out­line the de­sign of the X-ray elec­tron beam size mon­i­tor for the Ad­vanced Pho­ton Source Up­grade. Com­po­nents and an­tic­i­pated per­for­mance char­ac­ter­is­tics of the beam size mon­i­tor are out­lined.

  Within the up­grade of the APS stor­age ring to a multi-bend achro­mat lat­tice, 560 RF Beam Po­si­tion Mon­i­tors will be re­quired. The pro­jected beam sizes are below 10 mi­crons in both hor­i­zon­tal and ver­ti­cal planes, putting strin­gent re­quire­ments on the BPM elec­tron­ics res­o­lu­tion, long-term sta­bil­ity, beam cur­rent de­pen­dency, and in­stru­ment re­pro­ducibil­ity. For the APS-U pro­ject, the Lib­era Bril­liance+ in­stru­ment has been up­graded in tech­nol­ogy and ca­pa­bil­i­ties, in­clud­ing the in­de­pen­dent multi-bunch turn-by-turn pro­cess­ing and an im­proved al­go­rithm to fur­ther re­duce the cross­bar-switch ar­ti­facts. More than 140 in­stru­ments, equipped with 4 BPM elec­tron­ics each, are being de­liv­ered to Ar­gonne Na­tional Lab­o­ra­tory, con­sist­ing of the largest scale pro­duc­tion for In­stru­men­ta­tion Tech­nolo­gies. In this con­tri­bu­tion, the ex­ten­sive test con­di­tions to which the in­stru­ments were ex­posed and their re­sults will be pre­sented, as well as the beam-based long-term drift mea­sure­ments with dif­fer­ent fill pat­terns.
