The Real-time Edge AI for Dis­trib­uted Sys­tems (READS) pro­ject’s goal is to cre­ate a Ma­chine Learn­ing (ML) sys­tem for real-time beam loss de-blend­ing within the ac­cel­er­a­tor en­clo­sure, which houses two ac­cel­er­a­tors: the Main In­jec­tor (MI) and the Re­cy­cler (RR). In pe­ri­ods of joint op­er­a­tion, when both ma­chines con­tain high in­ten­sity beam, ra­dia­tive beam losses from MI and RR over­lap on the en­clo­sure¿s beam loss mon­i­tor­ing (BLM) sys­tem, mak­ing it dif­fi­cult to at­tribute those losses to a sin­gle ma­chine. In­cor­rect di­ag­noses re­sult in un­nec­es­sary down­time that in­curs both fi­nan­cial and ex­per­i­men­tal cost. The ML sys­tem will au­to­mat­i­cally dis­en­tan­gle each ma­chine¿s con­tri­bu­tions to those mea­sured losses, while not dis­rupt­ing the ex­ist­ing op­er­a­tions-crit­i­cal func­tions of the BLM sys­tem. Within this paper, the ML mod­els, used for learn­ing both local and global ma­chine sig­na­tures and pro­duc­ing high qual­ity in­fer­ences based on raw BLM loss mea­sure­ments, will only be dis­cussed at a high-level. This paper will focus on the evo­lu­tion of the ar­chi­tec­ture, which pro­vided the high-fre­quency, low-la­tency col­lec­tion of syn­chro­nized data streams to make real-time in­fer­ences.

The cur­rent pro­gram at Fer­mi­lab in­volves the con­struc­tion of a new su­per­con­duct­ing lin­ear ac­cel­er­a­tor (LINAC) to re­place the ex­ist­ing warm ver­sion. The new LINAC, to­gether with other planned im­prove­ments, is in sup­port of pro­ton beam in­ten­si­ties in the Main In­jec­tor (MI) that will ex­ceed 2 MW. Mea­sur­ing the trans­verse pro­files of these high in­ten­sity beams in a ring re­quires non-in­va­sive tech­niques. The MI uses ion­iza­tion pro­file mon­i­tors as its only pro­file sys­tem. An al­ter­na­tive tech­nique in­volves mea­sur­ing the de­flec­tion of a probe beam of elec­trons with a tra­jec­tory per­pen­dic­u­lar to the pro­ton beam. This type of de­vice was in­stalled in MI and ini­tial stud­ies of it have been pre­vi­ously pre­sented. This paper will pre­sent the sta­tus and re­cent stud­ies of the de­vice uti­liz­ing dif­fer­ent tech­niques.

The Pro­ton Im­prove­ment Plan - II (PIP-II) is a new lin­ear ac­cel­er­a­tor (LINAC) com­plex being built at Fer­mi­lab. It is based on su­per­con­duct­ing ra­diofre­quency cav­i­ties and will ac­cel­er­ate H ions to 800 MeV ki­netic en­ergy be­fore in­jec­tion into the ex­ist­ing Booster ring. Mea­sure­ments of the pro­file of the beam along the LINAC must be done by non-in­ter­cept­ing meth­ods due to the su­per­con­duct­ing cav­i­ties. The method cho­sen is pho­toion­iza­tion of a small num­ber of H by a fo­cused in­frared laser, aka laser­wire. The num­ber of ion­ized elec­trons is mea­sured as a func­tion of laser po­si­tion within the H beam. To aid in the de­sign of the col­lec­tion mech­a­nism, a sim­u­la­tion was writ­ten in MAT­LAB with input from the com­mer­cial elec­tro­mag­netic sim­u­la­tion, CST. This sim­u­la­tion cal­cu­lates the num­ber and po­si­tions of the lib­er­ated elec­trons and tracks them through the mag­netic col­lec­tion and H beam fields to the col­lec­tion point. Re­sults from this sim­u­la­tion for var­i­ous points along the LINAC will be shown.

One of the on-go­ing is­sues with the use of mi­crochan­nel plates (MCP) in the ion­iza­tion pro­file mon­i­tors (IPM) at Fer­mi­lab is the sig­nif­i­cant de­crease in gain over time. There are sev­eral pos­si­ble is­sues that can cause this. His­tor­i­cally, the as­sump­tion has been that this is aging, where the sec­ondary emis­sion yield (SEY) of the pore sur­face changes after some amount of ex­tracted charge. Re­cent lit­er­a­ture searches have brought to light the pos­si­bil­ity that this is an ini­tial ’scrub­bing’ ef­fect whereby ad­sorbed gasses are re­moved from the MCP pores by the re­moval of charge from the MCP. This paper dis­cusses the re­sults of stud­ies con­ducted on the IPMs in the Main In­jec­tor at Fer­mi­lab.
