“…Meanwhile, other readout concepts are being investigated. Free-space optical links, offer some advantages for interlayer communication by removing the problem of radiation damage of the optical fibers, together with opto-electromechanical devices, for an elegant implementation of intelligent front-end interconnects [167]. A feasibility study of the wireless technology integration at 60 GHz into silicon tracker detector has been reported in [168]; it represents a promising upcoming alternative to conventional data transmission.…”

The physics goals of high luminosity particle accelerators, from LHC to HL-LHC and to the next generation of lepton colliders, have set quite stringent constraints on the future needs at the Instrumentation Frontier. Many technologies are reaching their sensitivity limit and new approaches need to be developed to overcome the currently irreducible technological challenges. The detrimental effect of the material budget and power consumption represents a very serious concern for a high-precision silicon vertex and tracking detectors. One of the most promising areas is CMOS sensors offering low mass and potentially radiation-hard technology for the future proton-proton and electron-positron colliders, intensity frontier and heavy-ion experiments. MPGDs have become a well-established technique in the fertile field of gaseous detectors; these will remain the primary choice whenever the large-area coverage with low material budget is required. Vacuum tube technology is inherently fast and new developments include advances in microchannel plates for photomultipliers with a potential for a picosecondtime resolution in large systems. Several novel concepts of picosecond-timing detectors will have numerous powerful applications in particle identification, pile-up rejection and event reconstruction, and serve numerous scientific goals. The story of modern calorimetry is a textbook example of physics research driving the development of an experimental method. Silicon photomultipliers have seen a rapid progress in the last decade, becoming the standard solution for scintillator-based devices. The integration of advanced electronics and data transmission functionalities plays an increasingly important role and needs to be addressed. Bringing the modern algorithmic advances from the field of machine learning from offline applications to online operations and trigger systems is another major challenge. The timescales spanned by future projects in particle physics, ranging from few years to many decades, constitute a challenge in itself, in addition to the complexity and diversity of the required accelerator and detector R&D. This paper summarizes advances and recent trends in the instrumentation techniques for particle physics experiments, largely based on the presentations given at the International Conference "Instrumentation for Colliding Beam Physics" (INSTR-20), held at BINP Novosibirsk, Russia, from 24 to

“…We have also done development of several kinds of modulator-based free space optical links. Much of this work is described elsewhere [12,13]. Here, we discuss a kind of short distance link which might help with on-board triggering in silicon tracking detectors and which could be optimally implemented with modulators.…”

“…The steering could follow target motion of a few mm at 100 Hz within about 10 microns. We also built a similar system with an auxiliary steering laser at 850 nm and reflective path which could operate for displacements of roughly 1 cm [12,13]. These links operated with a LiNbO 3 modulator at 1 Gbps, 1550 nm, with no errors for hours while the target was in motion.…”

Optical links will be an integral part of future LHC experiments at various scales from coupled sensors to off-detector communication. We are investigating CW lasers and light modulators as an alternative to VCSELs. Light modulators are small, use less power, have high bandwidth, are reliable, have low bit error rates and are very rad-hard. We present the quality of the links at 10Gbps and the results of radiation hardness measurements for the modulators built based on LiNbO3, InP, and Si. Also we present results on modulator-based free space data links, steered by MEMS mirrors and optical feedback paths for the control loop.
