89. Radiation Tolerant Source Interface Unit for the ALICE Experiment

Mr Ervin DÉNES (KFKI Research Institute for Particle and Nuclear Physics, Budapest)

Oral

The ALICE Detector Data Link (DDL) is a high-speed optical link designed to interface the readout electronics of ALICE sub-detectors to the DAQ computers. The Source Interface Unit (SIU) of the DDL will operate in radiation environment. Tests showed that configuration loss of the ALTERA APEX II FPGA device used earlier on the DDL SIU card is only marginally acceptable. We developed a...

19. Radiation-Hard Optical Link for the ATLAS Pixel Detector

Mr Paul Douglas Jackson (Department of Physics, The Ohio state University)

13/09/2005, 14:40

Oral

We have developed a radiation-hard optical link for the ATLAS pixel detector at the LHC at CERN. The driver and receiver chips are implemented in 0.25 micron CMOS technology using enclosed layout transistors and guard rings for increased radiation hardness. The former drives the Vertical Cavity Surface Emitting Laser (VCSEL) diode to transmit 80 Mbit/s data from the detector. The...

28. The Production of the SCT Optical Links

Dr Anthony Weidberg (Nuclear Physics Laboratory)

13/09/2005, 15:05

Oral

The on detector optical links for the SCT have been produced and mounted on the detector. Most of the off-detector opto-electronics has also been produced and has been used to successfully read out modules assembled on barrels and End Cap disks. Many problems were encountered during the production and these will be described. The lack of modularity in the system design has been a major...

16. Final Results of the Industrial Production of CMS Tracker Analog Optohybrids

Dr Markus Friedl (HEPHY Vienna)

13/09/2005, 15:30

Oral

Approximately 15,000 analog optical transmitter modules with 2 or 3 channels each will be installed in the CMS experiment to read out the Silicon Strip Tracker. These Analog Optohybrids were produced in Austrian and Italian industries from mid- 2003 to mid-2005. After assembly, each unit was thoroughly tested for electrical and optical properties and all results are stored in the CMS...
