The CHORUS scintillating fiber tracker and opto-electronic readout system

APD Arrays for Scintillating Fiber Readout

An investigation is underway to determine the feasibility of planar processed, high gain, silicon avalanche photodiode arrays as a readout mechanism for scintillating fibers (SCIFI). Avalanche photodiode (APD) arrays are a compact and rugged alternative to photomultiplier tubes (PMTs). Since SCIFI usually yield a small number of photons compared with bulk scintillators, one goal of this investi...

MOF-based electronic and opto-electronic devices.

Metal-organic frameworks (MOFs) are a class of hybrid materials with unique optical and electronic properties arising from rational self-assembly of the organic linkers and metal ions/clusters, yielding myriads of possible structural motifs. The combination of order and chemical tunability, coupled with good environmental stability of MOFs, are prompting many research groups to explore the poss...

The electronic readout of the CMS tracking system

A description is given of the electronic readout system proposed by the CMS experiment for the microstrip tracker. It is an analogue system based on a front end chip development by RD20 and analogue optical links being developed by RD23. Both gas and silicon microstrips are read out by the same system with minor modifications to the front end chips to accommodate the different detector characte...

Scalable Opto-Electronic Network (SOENet)

In applications such as processor-memory interconnect, I/O networks, and router switch fabrics, an interconnection network must be scalable to thousands of high-bandwidth terminals while at the same time being economical in small configurations and robust in the presence of single-point faults. Emerging optical technology enables new topologies by allowing links to cover large distances but at ...
