PROGRAMMABLE TECHNOLOGIES WEB PAGE
This web site is dedicated to the design and use of programmable and quick-turn
technologies for radiation environment applications in CERN LHC experiments
Introduction
Programmable Logic Devices are replacing traditional logic circuits by
offering the advantages of high integration (small size, low power and
high reliability) without the disatvantages of custom ASICs (high non-recurring
engineering cost and high risk, especially in limited production volume).
Many project in LHC experiments require relatively smal number of logic
devices used in radiation environment. The intention of this page is to
collect information on radiation environment in LHC experiments, candidate
programmable devices with radiation test information and useful links.
Radiation Environment
Here I would like to collect the parameters of the radiation environment
which are necessary for component selection. This table is a sample,
contains data for the ATLAS Tile Calorimeter Front-end Link environment.
Total Dose per year: 100 Gy (10 KRad)
Source of total dose: Neutrons (from thermal to fast), Protons, Pions

This is a non-exhaustive list of the devices seem to be interesting an
I have some information on radiation behaviour. If there is no link of
a device, please write me
for information on that chip.
