  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.

It is well known that the ef­fi­ciency of an ad­vanced con­trol al­go­rithm like ma­chine learn­ing is as good as its data qual­ity. Much re­cent progress in tech­nol­ogy en­ables the mas­sive data ac­qui­si­tion from a con­trol sys­tem of mod­ern par­ti­cle ac­cel­er­a­tor, and the wide use of em­bed­ded con­trollers, like field-pro­gram­ma­ble gate ar­rays (FPGA), pro­vides an op­por­tu­nity to col­lect fast data from tech­ni­cal sub­sys­tems for mon­i­tor­ing, sta­tis­tics, di­ag­nos­tics or fault record­ing. To im­prove the data qual­ity, at the APS Up­grade pro­ject, a gen­eral-pur­pose data ac­qui­si­tion (DAQ) sys­tem is under ac­tive de­vel­op­ment. The APS-U DAQ sys­tem col­lects high-qual­ity fast data from un­der­neath em­bed­ded con­trollers, es­pe­cially the FPGAs, with the man­ner of time-cor­re­la­tion and syn­chro­nously sam­pling, which could be used for com­mis­sion­ing, per­for­mance mon­i­tor­ing, trou­bleshoot­ing, and early fault de­tec­tion, etc. This paper pre­sents the de­sign and lat­est progress of APS-U high-per­for­mance DAQ in­fra­struc­ture, as well as its prepa­ra­tion to en­able the use of ma­chine learn­ing tech­nol­ogy for APS-U, and its use cases at APS.
