Status of activities of the WP4 on Radiopurity of Materials
Pia Loaiza
ILIAS meeting, Modane, January 12th, 2005
The database is stored in a dedicated server of the
Centre de Calcul de Lyon.
It is built using MySQL system combined with php scripts which allow to
communicate from the web page to the database.
The data is load from a text file : format required is easily converted if original
format is an Excel file.
Find it in : http://www-lsm.in2p3.fr/ilias/database.html.
( Just starting with some data …)
Up to now, I have got data from :
Jorge Puimedón from Canfranc for the collaborations : ANAIS, CAST and
ROSEBUD.
Gerard Nollez and Claudine Goldbach from LSM, for EDELWEISS
(have to be written in proper format to be read in the database).
Data planned to be included (after some work…):
Data from UKDM site.
Data from publications.
At LRT2004, SNO people proposed to make their measurements available
to be included in the database.
Task b) Selection of materials to be investigated in terms of radiopurity levels
First step :
Systematic comparison of measurements in the different labs:
cross-check with one or more reference samples to compare instrumentation
and possible systematics in the analysis method.
