Foreword to the ICALEPCS 2023 Proceedings
The 19th International Conference on Accelerator and Large Experimental Physics Control
Systems (ICALEPCS 2023) was held from 9th to 13th October 2023 in Cape Town, SouthAfrica.
The conference was hosted by the South African Radio Astronomy Observatory (SARAO),
and the conference’s Local Organising Committee was advised by two committees made upof members from the three regions the International Scientific Advisory Committee (ISAC)
and the Programme Committee (PC).
The ISAC comprised 35 members and was chaired by Andy Götz from ESRF. The PC
was made up of 32 members and co-chaired by Karen White from the ORNL and Daniel
Flath from SLAC.
In total there were 427 conference registrations of which 17 were from students. CERN
had the most contributions followed by SLAC. The breakdown of contributors by region was
as follows: 231 from Europe, 81 from North America, 24 from Asia, 18 from Africa, eightfrom South America and one from Australasia.
For the proceedings, 363 papers were uploaded and processed to be included in theproceedings. ICALEPCS 2023 once again put a strong emphasis on having high qualityand diverse speakers. Ms. Linda Njomane, one of the keynote speakers, spoke about
Women in Engineering, challenges and opportunities they get and how the stats look like inSouth Africa.
The scientific programme was drawn up by the PC. The committee did an excellent job
choosing topics and talks and encouraging experts to present their work. Parallel sessions
were necessary, as have been in the past. Out of a total of 31 sessions, 14 were parallel.
There were eight pre-conference workshops held on the weekend preceding the conference. The pre-conference workshops were well attended: on the Saturday, 212 participants
attended workshops and on Sunday 240.
The workshops focused on the following topics:• Tango controls• EPICS collaboration meeting• Control system cyber security• Motion control (MOCRAF)• PLC based control systems• Controls GUI strategies• Efficiency through automation• Data science and machine learning
The ICALEPCS Lifetime Achievement Award (LAA) was awarded at ICALEPCS 2023 totwo long standing members of the community:• Karen White for her many years contributing to ICALEPCS and EPICS communities
and the critical role she played in advancing diversity in engineering and• Volker RW Schaa for his many years maintaining the JACoW system for conference
proceedings and editing the ICALEPCS proceedings and multiple other conference
series.

The ISAC accepted the bid for ICALEPCS 2027 to be held in Ibaraki, Japan to be hosted
by the High Energy Accelerator Research Organization (KEK).
As chairs we would like to thank everyone who contributed to making ICALEPCS 2023
a resounding success and a memorable event. The conference was the result of many
peoples work and support both financial and moral.
We thank all the sponsors and exhibitors who helped finance the conference:• Cosylab• S2 Innovation• Observatory Sciences• IOxOS Technologies• Beckhoff Automation• D-TACQ Solutions• RadiaSoft• iThemba LABS
• Faraday Motion Controls• The South African Radio Astronomy Observatory (SARAO)• ICEXThe ISAC chair and committee did a great job advising the LOC during the two years
leading up to the conference. The PC excelled at shaping the scientific programme, and theeditors did a stellar job of editing the many abstracts and papers to ensure that the submissions were of high quality. The delegates made the conference a success by participatingwith interesting and relevant talks and questions. And lastly, a heartfelt thank you to SARAO,
the host institute, and the LOC who helped and provided support for ICALEPCS 2023.

We look forward to seeing everyone in Chicago in 2025!
