32. When the Bare-Metal Returns: A Centralized Data Plane for Elettra 2.0 Control and Simulation

Giulio Gaio (Elettra Sincrotrone Trieste)

10/14/26, 10:05 AM

Control Architecture and Strategies

Oral

Elettra 2.0 control system will consolidate time-critical acquisition, processing, and actuation onto a dual HPC 512 HT core server. Using the DPDK kernel bypass, this data plane is designed to acquire Turn-by-Turn streams from 168 BPMs, 4 LLRFs and 120 BLMs, and drive about 1200 magnet power supplies at 100 kHz for RT feedback purposes, with a total of 160 Mpps data rate with a few...

15. RF Beam Noise Feedback System for the High-Luminosity LHC Crab Cavities

Dimitar Marinov (CERN)

Control Hardware Platforms

Oral

The High-Luminosity Large Hadron Collider (HL-LHC) project at CERN is set to introduce a series
of major upgrades across the LHC complex, including the implementation of crab cavities,
applied for the first time in a hadron machine. These cavities are designed to increase beam
luminosity by compensating for the geometric luminosity reduction caused by the crossing
angle at the interaction...

38. Photonic RF Phase Monitor

Russell Wilcox (LBNL)

System Identification

Oral

We describe a timing-stabilized RF amplitude and phase monitor, using optical interferometry. Unlike RF-over-fiber using AM, RF voltage drives an EO phase modulator at the sensor. No bias is needed, and light is provided by the receiving system. The optical signal goes back through fiber and is interfered with an optical LO at the receiver, a coherent telecom component with optical I and Q...
