TWEPP 2025 conference app: offline agenda + Indico sync

Electronics Engineering Meets Island Connectivity

TWEPP is the annual meeting point for engineers and physicists working on detector electronics, trigger systems, data-acquisition architectures, and radiation-tolerant ASICs for experiments at CERN, DESY, and other facilities. The 2025 edition took place at the Conference Centre of the University of Crete in Rethymno—a stunning seaside setting that came with a practical drawback: mobile connectivity on the venue terrace and in some basement seminar rooms was unreliable.

Offline-First for an Island Venue

HEPCon’s service-worker architecture cached the complete timetable, all abstracts, and speaker information after the initial load. This meant attendees could browse the programme during coffee breaks on the terrace overlooking the Mediterranean, walk into a basement poster room, or ride the hotel shuttle—all without losing access to the schedule. The LOC reported that offline usage spiked during the poster sessions held in a room with particularly weak cellular signal.

Real-Time CERN Indico Sync

TWEPP’s programme was maintained in CERN Indico, and late changes were common as speakers adjusted slides or sessions were reorganised to accommodate last-minute contributions. HEPCon’s two-way sync propagated every Indico update to the mobile and web apps in near-real-time. The LOC never had to manually duplicate a single change—saving an estimated full day of volunteer coordination.

Sponsor Visibility for Industry Partners

TWEPP attracts significant industry sponsorship from ASIC foundries, FPGA vendors, and radiation-test facilities. HEPCon’s sponsor-banner placements and analytics dashboard gave each sponsor verified impression and tap-through data—replacing anecdotal “our logo was on the website” feedback with concrete numbers. Two sponsors told the LOC that the analytics report helped justify their sponsorship renewal internally.

Technical Search for a Technical Audience

TWEPP attendees often search for specific ASIC names, FPGA families, or detector subsystem acronyms. HEPCon’s full-text search indexed every contribution title, abstract, and speaker name, making it trivial to find all talks mentioning “lpGBT” or “Timepix4” across eight parallel tracks.
