The aim of the International Diagnostic Database is to obtain a good
insight in the usage and reliability of diagnostics that are used on
present day devices. For future burning plasma experiments we want to get
as good as possible an idea what are the specific problems that are related
to certain diagnostics. The information is relevant as well for all
scientists working with diagnostics on present day devices.
The measurement technique has two aspects: the measurement hardware and the
underlying physics/interpretation. In practice, problems can occur in
either area and the fields in the database try to bring this out. An
example is the measurement of Te(r) by ECE: The measurement hardware may be
working fine but the measurement is perturbed by suprathermals or runaways.
We need information on both aspects.
The experience is that diagnostics at any machine are improved when time
evolves: diagnostics that had a number of problems some years ago might be
functioning reliably and satisfactory now. However, we would like to
discourage scientists to update the information on their diagnostics in
such a way that all information about the past problems disappear. Instead
we would like to explicitly know what has been done to remedy the problems.
In the respective fields one can mention the problem and then describe how
it has been solved.
Please use a separate entry for each individual measurement techniques.
E.g. for impurity spectroscopy fill out separate forms for visible, VUV,
X-ray, CXRS etc. Otherwise the results will become very confusing.
Only contributors to the International Diagnostic Database have active
access. Accounts and passwords are allocated to teams rather than
individuals. New teams can request an account and password via an e-mail to
the database manager: donne@rijnh.nl
The database is owned by the teams that have contributed to its contents.
The use of information from this database in publications and/or public
presentations is prohibited without permission from the contributing teams.
