Simmering frustration among French synchrotron researchers over the government's reluctance to finance the construction of a third generation facility boiled over this week. Staff at the national synchrotron facilities accused the science minister, Claude Allègre, of making misleading statements to the National Assembly on the need for a new facility.
Plans for a FF1 billion (US$182 million) 2.15-GeV source, Soleil, to replace the ageing LURE facilities near Paris (800 MeV and 1.85 GeV), have received backing from Catherine Bréchignac, director general of the Centre National de la Recherche Scientifique and Yannick d'Escatha, head of the French Atomic Energy Commission (see Nature 390, 212; 1997). But the scheme has been frozen by Allègre as part of a review of big science spending.
The French proposal was ‘strongly endorsed’ in a report on European synchrotron radiation, issued last week by an independent panel of the European Science Foundation. The report warned that, unless new sources were built, Europe “risked losing its lead in certain aspects of biological and biomedical research”.
Synchrotron radiation is used by scientists from many disciplines to reveal the structure of biological molecules. The panel points out that demand will increase as the plethora of genome projects creates a need to determine more protein structures.
But in the French National Assembly last week Allègre argued that Europe had a surplus of synchrotron facilities. “Within two years there will be seven third-generation synchrotrons in Europe,” he said. “There are two in the United States. Do you really think we need an eighth without a preliminary inquiry? Do you know an area where Europe needs four times as many machines as the United States?”
Allègre reiterated his view that most big science facilities should be European, and that national facilities should be the exception. He also asserted that Soleil would provide employment for only 40 people, and that the construction of synchrotrons in Germany and Italy would free user time at the European Synchrotron Radiation Facility (ESRF) in Grenoble, France.
Allègre spoke in response to questions from Pierre Lasbordes, a member of the neo-Gaullist RPR party, whose Essonne constituency is home to LURE and a candidate to host Soleil. Lasbordes said that the Paris region agreed last year to pay more then half the costs of a new machine.
“We are only waiting for you,” said Lasbordes, describing Soleil as “indispensable”. The delays were “all the more regrettable” given that new facilities were being built in several European countries, including the United Kingdom.
LURE's director Robert Comés and senior staff at the facility have written to Allègre, claiming that his declaration to parliament was inaccurate, and showed his “lack of knowledge” of the project. They claim the United States has plans to increase its number of synchrotron sources to seven.
The researchers contest the need for a further inquiry into the case for Soleil, arguing that it has been approved by several assessments over the past seven years. The letter challenges Allègre's estimate of employment at the facility, pointing out that LURE itself employs 350 full time staff, and is used by almost 2,000 researchers annually.
It also challenges Allègre's claim that the refurbishment of Italian and German facilities will free user time at ESRF, adding that soft radiation produced by Soleil will find different applications to the hard X-rays from the 6-GeV ESRF machine. The letter also points out that France's share of user time already exceeds its financial participation in the ESRF.
