- The project is evaluating radiation hard Si-on-Insulator (SOI) CMOS
integrated circuit technology from Thomson Composants Speciales, Grenoble
for application in the high radiation environments of LHC experiments.
Demonstrators of typical analog front-end chips are developed in the
1.2 micron HSOI3-HD process. Devices and circuits are irradiated with doses
of up to several tens of Mrad, and the effect of radiation damage on
performance is measured.

RD-12: Timing, trigger and control (TTC) systems for LHC detectors - Spokesman: B.G. Taylor
- The project is developing a multi-function optoelectronic TTC distribution
system which can meet the requirements of the different subdetectors of the
LHC experiments. A laser transmitter, modulator, encoder and VMEbus interface
are being developed as well as a subminiature radiation-hard optical fibre
connector, active device mount and photodetector/preamplifier. A timing
receiver ASIC is being designed which will generate the full range of decoded
signals from a single input. The system incorporates programmable coarse and
fine deskew facilities to compensate for different particle flight times and
detector, electronics, propagation and test generator delays. It can also
transmit asynchronous slow controls and data such as individually-addressed
channel enables and calibration parameters to several thousand destinations.

RD-13: A scalable data taking system at a test beam for LHC - Spokesman: L.Mapelli
- The project investigates system components and integration aspects for the
building of complex real-time systems. The main goals are to build a scalable
Unix-based core system, for which a prototype is now operating in a test beam,
and to evaluate the multiple commercial components that are candidates for
inclusion in such a system. Software engineering techniques to be used in the
design of large real-time systems are also part of the investigations.

RD-16: A digital front-end and readout microsystem for calorimetry at LHC - Spokesmen: G.Goggi and B.Lofstedt
- The project (dubbed FERMI) develops a multi-channel front-end microsystem in
Si-on-Si multi-chip technology, mainly aimed at the readout of calorimeter
signals in LHC experiments. The system functions are dynamic range compression,
digitisation at 80 MHz, digital signal processing, special signal agregation
for triggering, and storage in with management of buffer memories. Many system
parts have already been implemented and demonstrated.

- The project explores the manufacturing and operation of pixel detectors
('imaging' or 'smart' detectors) and their readout, in hybrid technology with
bump bonding to CCD readout chips, or as monolithic detectors using multi-chip
modules. A large number of chips has already been manufactured with pixel size
from 50 to 500 microns, and are now subjected to various tests in- and ouside
the collaboration.

RD-23: Optoelectronic analogue signal transfer for LHC detectors - Spokesmen: G.Stefanini and F.Vasey
- The project explores the technologies which allowing a transmission of analogue
signals on optical fibres, using miniaturised electro-optical intensity
modulators. The key issues, pursued with industry partners, are the development
of arrays of modulators to be mounted on Si detectors or microstrip gas
chambers, and the development of transceiver arrays, to be mounted on readout
modules. Radiation-hard fibres and multi-way optical connectors are a natural
subject of study as well.

RD-24: Applications of the Scalable Coherent Interface to data
acquisition at LHC - Spokesmen: A.Bogaerts and H.Muller
- RD24 is in close collaboration with industry partners in the development,
evaluation, and demonstration of components based on the high-bandwidth
and low-latency SCI protocol. SCI connections are expected to be candidates for
the interconnection of buffers and trigger components (processors),
possibly also for versatile high-frequency switching of data streams. SCI may
also be the basis for a scalable event builder. Several chips have been
delivered and evaluated, interfaces to Futurebus+, Turbochannel, SBUS, C40
DSP-s have been designed and demonstrated. Others such as PCI, VME and Fastbus
are
close to completion. Serial and parallel optical transmission has been
demonstrated at respectively 1 and 2 Gigabits/s. A MODSIM based simulation
package (SCILab) is available.

RD-31: NEBULAS: An asynchronous self-routing packet switching network
architecture for event building in high rate experiments - Spokesmen: M.Letheren and J.P.Dufey
- The project evaluates and demonstrates architectures for parallel, data-driven,
and scalable event building in high-rate experiments. Under study are
industrial switching fabrics based on the ATM or fibre channel standards and
the possibility of a custom-designed fabric optimised for the event building
application. Demonstrator systems are in buildup; performance evaluations via
computer models have also been done.

RD-38: CICERO: A study on generic control systems for large scale
experiments at LHC - Spokesman: J.M.Le Goff
- Due to the large number of sensors to be monitored and controlled, the 'slow'
controls in LHC experiments will be complex to implement reliably and expensive
to maintain. The CICERO project studies the aspects of implementing
cost-effective control systems based on industrial components and modern
methodologies (object-oriented software) and standards. Partners in the project
also include application partners in space research, where standardisation in
this domain has been recognised long ago to be imperative.
-
RD-41: Object oriented approach to software for LHC experiments - Spokesman: K.Bos
- The project studies the viability of an object-oriented approach to the
development of analysis code in LHC experiments. The key issues of abandoning
the Fortran + support libraries approach are under evaluation, prototype
re-developments of well-defined programs are used as milestones, the
interrelation with the use of CASE tools and with project management are
evaluated.
