proposals submitted for 1st period 2004

by users' office (sincrotrone trieste)

.

For the first period of 2004 (January - June) 297 proposals for experiments have been received by Elettra until the deadline at August, 31. They may be broken down according to countries of origin of the submitting research group in the following way:

  . 

Italy:	120	40.4%
EU member states:	105	35.4%
other European countries	31	10.4%
non-European countries:	41	13.8%

 . 

In total 6111 shifts have been requested, an increase of 23% respective to the second period of 2003, when users applied for 4986 shifts. The shifts may be subdivided in:

  . 

Italy:	2359	38.6%
EU member states:	2473	40.5%
other European countries	641	10.5%
non-European countries:	638	10.4%

  . 

Considering the EU member states, most proposals have been submitted by French users (44 proposals, requesting 1027 shifts), followed by German (17 proposals, 376 shifts) and British (16 proposals, 357 shifts) groups. 59% of the non-European applications come from India (24 proposals, 351 shifts), the others from Australia, Canada, China, Japan and the USA. In total, researchers from 26 countries applied for beamtime at Elettra for the first period 2004.

elettra coordinates EU network of light sources

Elettra acts as coordinator of a network of light sources which receives large European grant

In the Framework Program 6 of the European Union, it is possible to obtain support for « Integrated Infrastructure Initiatives » (I3’s for short), aiming at extending and facilitating access of scientists  to large scientific facilities which are present in some countries. Under coordination of the Elettra Laboratory, a group of 16 synchrotron and free electron laser sources in Europe submitted a proposal in April, for a five year program aiming at granting free transnational access to the facilities, at developing new instumentation and techniques by international collaboration on a wide-ranging R&D activity, and finally at promoting integration of the community at the European level through the support of workshops, conferences and schools. The proposal received high marks from the referees and is approved for financing up to a total of 27 M Euro for the 5 year period. Presently, Elettra, as coordinator of the whole project, is leading the negotiations with the European Commission to come to the final version of the contract. It is expected that the contract could start in January 2004.

new beamstopper for XRD1

by fulvio bille (sincrotrone trieste)

.

A new beamstopper (BSD) at the X-Ray Diffraction 1 beamline has been integrated into the beamline access controll system. This permits a better operational independence between the lines XRD1 and SAXS sharing exit 5.2. Keeping this beamstopper closed, it is possible now to enter the optical hutch which contains the monochromator also while the  front-end remains open, e.g. when measurements are performed at the SAXS beamline. Furthermore it is possible to enter the monochromator hutch during injections, which allows to the beamline personnel to exploit machine shifts and injections for maintenance operations.

The new situation is depicted on the web-page of the "BACS-supervisor" on

injection rules at elettra

by emanuel karantzoulis (sincrotrone trieste)

.

During the last group leader meetings, the injection rules of Elettra have been discussed and confirmed in the following way:

 

Injections are performed two times per day at 9:30 and 21:00 except if

• an injection has already taken place within two hours before this time, or if
  .

• at 2.0 GeV the current is higher than 170 mA and the product <<current per average life-time>> is larger than 2 Ah within 1.5 hours before the usual injection time;
  .

• at 2.4 GeV the current is higher than 110 mA and the product <<current per average life-time>> is larger than 3 Ah within 1.5 hours before the usual injection time;

in the latter two cases an injection will anyhow be performed if all the operating beamlines agree and ask to inject. Furthermore it was decided that at 2.4 GeV a current of 150 mA should usually be injected.

 

The rules imply that in the current state at 2.0 GeV one injection in 36 hours will usually take place.
