	Funding: This work was performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344 The Na­tional Ig­ni­tion Fa­cil­ity (NIF) is the world’s largest and most en­er­getic 192-laser-beam sys­tem which con­ducts ex­per­i­ments in High En­ergy Den­sity (HED) physics and In­er­tial Con­fine­ment Fu­sion (ICF). In De­cem­ber 2022, the NIF achieved a sci­en­tific break­through when, for the first time ever, the ICF ig­ni­tion oc­curred under lab­o­ra­tory con­di­tions. The key to the NIF’s ex­per­i­men­tal prowess and ver­sa­til­ity is not only its power but also its pre­cise con­trol. The NIF con­trols and data sys­tems place the ex­per­i­menter in full com­mand of the laser and tar­get di­ag­nos­tics ca­pa­bil­i­ties. The re­cently up­graded Mas­ter Os­cil­la­tor Room (MOR) sys­tem pre­cisely shapes NIF laser pulses in the tem­po­ral, spa­tial, and spec­tral do­mains. Apart from the pri­mary 10-me­ter spher­i­cal tar­get cham­ber, the NIF laser beams can now be di­rected to­wards two more ex­per­i­men­tal sta­tions to study laser in­ter­ac­tions with op­tics and large full beam tar­gets. The NIF’s wide range of tar­get di­ag­nos­tics con­tin­ues to ex­pand with new tools to probe and cap­ture com­plex plasma phe­nom­ena using x-rays, gamma-rays, neu­trons, and ac­cel­er­ated pro­tons. While the in­creas­ing neu­tron yields mark the NIF’s steady progress to­wards ex­cit­ing ex­per­i­men­tal regimes, they also re­quire new mit­i­ga­tions for ra­di­a­tion dam­age in con­trol and di­ag­nos­tic elec­tron­ics. With many NIF com­po­nents ap­proach­ing 20 years of age, a Sus­tain­ment Plan is now un­der­way to mod­ern­ize NIF, in­clud­ing con­trols and in­for­ma­tion sys­tems, to as­sure NIF op­er­a­tions through 2040.

WE2BCO03	Ongoing Improvements to the Instrumentation and Control System at LANSCE	979
	M. Pieck, C.D. Hatch, H.A. Watkins, E.E. Westbrook LANL, Los Alamos, New Mexico, USA
	Funding: This work was supported by the U.S. DOE through the Los Alamos National Laboratory (LANL). LANL is operated by Triad National Security, LLC, for the NNSA of U.S. DOE - Contract No. 89233218CNA000001 Re­cent up­grades to the In­stru­men­ta­tion and Con­trol Sys­tem at Los Alamos Neu­tron Sci­ence Cen­ter (LAN­SCE) have sig­nif­i­cantly im­proved its main­tain­abil­ity and per­for­mance. These changes were the first strate­gic steps to­wards a larger vi­sion to stan­dard­ize the hard­ware form fac­tors and soft­ware method­olo­gies. Up­grade ef­forts are being pri­or­i­tized though a risk-based ap­proach and funded at var­i­ous lev­els. With a major re­cap­i­tal­iza­tion pro­ject fin­ished in 2022 and mod­ern­iza­tion pro­ject sched­uled to start pos­si­bly in 2025, cur­rent ef­forts focus on the con­tin­u­a­tion of up­grade ef­forts that started in the for­mer and will be fin­ished in the later time frame. Plan­ning and ex­e­cut­ing these up­grades are chal­leng­ing con­sid­er­ing that some of the changes are ar­chi­tec­tural in na­ture, how­ever, the func­tion­al­ity needs to be pre­served while tak­ing ad­van­tage of tech­nol­ogy pro­gres­sions. This is com­pounded by the fact that those up­grades can only be im­ple­mented dur­ing the an­nual 4-month out­age. This paper will pro­vide an overview of our vi­sion, strat­egy, chal­lenges, re­cent ac­com­plish­ments, as well as fu­ture planned ac­tiv­i­ties to trans­form our 50-year-old con­trol sys­tem into a mod­ern state-of-the-art de­sign.

WE2BCO04	Maintaining a Hybrid Control System at ISIS with a Vsystem/EPICS Bridge	986
	K.R.L. Baker, I.D. Finch, M. Romanovschi STFC/RAL/ISIS, Chilton, Didcot, Oxon, United Kingdom
	The mi­gra­tion of the con­trols sys­tem for the ISIS ac­cel­er­a­tor from Vsys­tem to EPICS pre­sents a sig­nif­i­cant chal­lenge and risk to day-to-day op­er­a­tions. To min­imise this im­pact through­out the tran­si­tion, a soft­ware bridge be­tween the two con­trol sys­tems has been de­vel­oped that al­lows the phased port­ing of HMIs and hard­ware. The hy­brid Vsys­tem and EPICS sys­tem also al­lows the con­tin­ued use of ex­ist­ing feed­back con­trol ap­pli­ca­tions that now re­quire in­ter­ac­tion be­tween both con­trol sys­tems, for ex­am­ple the halo steer­ing op­er­a­tion in Tar­get Sta­tion 1. This work de­scribes the im­ple­men­ta­tion of this bridge, re­ferred to as PVE­cho, for the map­ping of Vsys­tem chan­nels to EPICS PVs and vice versa. The po­si­tion within the wider ISIS con­trols soft­ware stack is out­lined as well as how it utilises Python li­braries for EPICS. Fi­nally, we will dis­cuss the soft­ware de­vel­op­ment prac­tices ap­plied that have al­lowed the bridge to run re­li­ably for months at a time.

WE2BCO05	Continuous Modernization of Control Systems for Research Facilities	993
	K. Vodopivec, K.S. Whitepresenter ORNL, Oak Ridge, Tennessee, USA
	Funding: This work was supported by the U.S. Department of Energy under contract DE-AC0500OR22725. The Spal­la­tion Neu­tron Source at Oak Ridge Na­tional Lab­o­ra­tory has been in op­er­a­tion since 2006. In order to achieve high op­er­at­ing re­li­a­bil­ity and avail­abil­ity as man­dated by the spon­sor, all sys­tems par­tic­i­pat­ing in the pro­duc­tion of neu­trons need to be main­tained to the high­est achiev­able stan­dard. This in­cludes SNS in­te­grated con­trol sys­tem, com­pris­ing of spe­cial­ized hard­ware and soft­ware, as well as com­put­ing and net­work­ing in­fra­struc­ture. While ma­chine up­grades are ex­tend­ing the con­trol sys­tem with new and mod­ern com­po­nents, the es­tab­lished part of con­trol sys­tem re­quires con­tin­u­ous mod­ern­iza­tion ef­forts due to hard­ware ob­so­les­cence, lim­ited life­time of elec­tronic com­po­nents, and soft­ware up­dates that can break back­wards com­pat­i­bil­ity. This ar­ti­cle dis­cusses chal­lenges of sus­tain­ing con­trol sys­tem op­er­a­tions through decades of fa­cil­ity life­cy­cle, and pre­sents a method­ol­ogy used at SNS for con­tin­u­ous con­trol sys­tem im­prove­ments that was de­vel­oped by an­a­lyz­ing op­er­a­tional data and ex­pe­ri­ence.

WE2BCO06	EPICS Deployment at Fermilab	997
	P.M. Hanlet, J.S. Diamond, M. Gonzalez, K.S. Martin Fermilab, Batavia, Illinois, USA
	Fer­mi­lab has tra­di­tion­ally not been an EPICS house, as such ex­per­tise in EPICS is lim­ited and scat­tered. How­ever, PIP-II will be using EPICS for its con­trol sys­tem. Fur­ther­more, when PIP-II is op­er­at­ing, it must to in­ter­face with the ex­ist­ing, though mod­ern­ized (see ACORN) legacy con­trol sys­tem. We have de­vel­oped and de­ployed a soft­ware pipeline that ad­dresses these needs and pre­sents to de­vel­op­ers a tested and ro­bust soft­ware frame­work, in­clud­ing tem­plate IOCs from which new de­vel­op­ers can quickly gain ex­pe­ri­ence. In this pre­sen­ta­tion, we will dis­cuss the mo­ti­va­tion for this work, the im­ple­men­ta­tion of a con­tin­u­ous in­te­gra­tion/con­tin­u­ous de­ploy­ment pipeline, test­ing, tem­plate IOCs, and the de­ploy­ment of user ap­pli­ca­tions. We will also dis­cuss how this is used with the cur­rent PIP-II test­stand and lessons learned.

WE2BCO07	15 Years of ALICE DCS	1002
	P.Ch. Chochula, A. Augustinus, P.M. Bond, A.N. Kurepin, M. Lechman, D. Voscek CERN, Meyrin, Switzerland O. Pinazza INFN-Bologna, Bologna, Italy
	The ALICE ex­per­i­ment stud­ies ultra rel­a­tivis­tic heavy ion col­li­sions at the Large Hadron Col­lider at CERN. Its De­tec­tor Con­trol Sys­tem (DCS) has been en­sur­ing the ex­per­i­ment safety and sta­bil­ity of data col­lec­tion since 2008. A small cen­tral team at CERN co­or­di­nated the de­vel­op­ments with col­lab­o­rat­ing in­sti­tutes and de­fined the op­er­a­tional prin­ci­ples and tools. Al­though the basic ar­chi­tec­ture of the sys­tem re­mains valid, it has had to adapt to the changes and evo­lu­tion of its com­po­nents. The in­tro­duc­tion of new de­tec­tors into ALICE has re­quired the re­design of sev­eral parts of the sys­tem, es­pe­cially the front-end elec­tron­ics con­trol, which trig­gered new de­vel­op­ments. Now, the DCS en­ters the do­main of data ac­qui­si­tion, and the con­trols data is in­ter­leaved with the physics data stream, shar­ing the same op­ti­cal links. The pro­cess­ing of con­di­tions data has moved from batch col­lec­tion at the end of data-tak­ing to con­stant stream­ing. The grow­ing com­plex­ity of the sys­tem has led to a big focus on the op­er­a­tor en­vi­ron­ment, with ef­forts to min­i­mize the risk of human er­rors. This pre­sen­ta­tion de­scribes the evo­lu­tion of the ALICE con­trol sys­tem over the past 15 years and high­lights the sig­nif­i­cant im­prove­ments made to its ar­chi­tec­ture. We dis­cuss how the chal­lenges of in­te­grat­ing com­po­nents de­vel­oped in tens of in­sti­tutes world­wide have been mas­tered in ALICE. This proposed contribution is complemented by poster submitted by Ombretta Pinazza who will explain the user interfaces deployed in ALICE.
