A Radiation Tolerant Gigabit Serializer for LHC Data Transmission

In the future LHC experiments, some data acquisition and trigger links will be based on Gbit/s optical fiber networks. In this paper, a configurable radiation tolerant Gbit/s serializer (GOL) is presented that addresses the high-energy physics experiments requirements. The device can operate in four different modes that are a combination of two transmission protocols and two data rates (0.8 Gbit/s and 1.6 Gbit/s). The ASIC may be used as the transmitter in optical links that, otherwise, use only commercial components. The data encoding schemes supported are the CIMT (G-Link) and the 8B/10B (Gbit-Ethernet & Fiber Channel). To guarantee robustness against total dose irradiation effects over the lifetime of the experiments, the IC was fabricated in a standard 0.25 µm CMOS technology employing radiation tolerant layout practices. The device was exposed to different irradiation sources to test its sensitivity to total dose effects and to single effects upsets. For this tests, a comparison is established with a commercial serializer. I

The Gigabit Link Interface Board (GLIB), a flexible system for the evaluation and use of GBT-based optical links

The Gigabit Link Interface Board (GLIB) is an evaluation platform and an easy entry point for users of high speed optical links in high energy physics experiments. Its intended use ranges from optical link evaluation in the laboratory to control, triggering and data acquisition from remote modules in beam or irradiation tests. The GLIB is an FPGA-based Advanced Mezzanine Card (AMC) conceived to serve a small and simple system residing either inside a Micro Telecommunications Computing Architecture (mu TCA) crate, or on a bench with a link to a PC. This paper presents the architecture of the GLIB, its features as well as examples of its use in different setups

A Data Acquisition System for a Beam-Tagging Hodoscope used in Hadrontherapy Monitoring

International audienceFor ion-range monitoring in Hadrontherapy, we propose a high throughput data acquisition (DAQ) system to be associated with a beam hodoscope to perform spatial and temporal labeling. The DAQ system can incorporate up to eight dedicated readout boards in parallel for adapting the resolution of the scintillating-fiber hodoscope. It also includes a μTCA board, a reference clock board and a computer. The system can be coupled with other detection systems such as Compton cameras, and collimated cameras
