Putting it all together: radiation-tolerant lighting in CERN's Proton Synchrotron (PS)

About

This talk will present the full lifecycle of an open hardware project from initial design to repeat procurement, and share the most important lessons learned.

One of the most ambitious projects for LS2 was the electrical refurbishment of the PS accelerator. A huge part of this project was the design, development, procurement and installation of the first generation of radiation tolerant LED lights, designed under the CERN open hardware licence. I will be sharing my experience with the whole process, from identifying the requirements for new lights, all the way to having a contractor install them and following up performance several years later. The design has been a success and a new contract was recently signed for a second generation of lights to go into the SPS accelerator. The architecture has been adopted by EN-AA for flashing warning beacons in the LHC, a version has been adapted for the American market and is installed at SLAC. You can even find them in the Australian Synchrotron in Melbourne.

The talk will cover the following points: • Why can't you buy radiation tolerant LED lights off the shelf? • A very (very) short primer on radiation effects in electronics. • Justifying an open hardware approach to management. • How we designed for radiation without batch & lot qualification. • Getting the design CE certified. • What about patent infringement? • Updating and adapting the design for new applications..
