Minutes on the 1st TARI FP7 USP Meeting on May 28, 2009 at LNF

Participants: Paolo Calvani, Catia Conti, Jean-Pierre Egger, Daniela Ferrucci, Carlo Guaraldo and Paul Kienle (Chairperson). Excused: Fabio Bossi and Calogero Natoli.

The meeting was opened by P. Kienle congratulating C. Guaraldo for the success of the Hadron Physics 2 program being finally commissioned by the EU following more than one year extremely difficult negotiations,

C. Guaraldo gave a short introduction on the FP7, Hadron Physics 2 program which succeeded in a strong competition, but suffered a reduction by a factor of two. The LNF access program is thus reduced to 30 month with 1500 man-days per year.

C. Guaraldo gave a rather detailed status report of DAΦNE in place of G Mazitelli. DAΦNE started operation January 16 for 84 days until May 15. SIDDHARTA could made use of less than 30% of this time due to various technical reasons. On the BTF facility 80% of the time offered was used.
For SIDDHARTA it presents a critical situation to perform the foreseen high precision experiments. There will be a shut down on August 10, but 1.4 M€ for electrical power to run the machine are actually missing. SIDDHARTA needs 400 pb-1 for kaonic hydrogen and further 200 pb-1 for kaonic deuterium until October 2009. In November 2009 KLOE 2 will roll in and take up operation in February 2010.

 

Examination and selection of proposals for Hadron Physics

Proposal No.2 by W. Kluge, “KLOE Physics, hadronic cross sections”

This proposal consists of two parts: (i) Recomissioning of the KLOE gas system by the experimental physicists (Kluge, Denig, Müller), and (ii) further analysis of data taken up to 2006. The data analysis will give important information on the strong interaction contribution to the vacuum polarization and a possible solution of the 3.3 s experimental/theoretical differences for the muon anomalous magnetic moment. The experimental KLOE part is approved but theoretical progress can be also achieved by other means than meetings in Frascati. We therefore propose 104 days for the three experimentalists and 66 days for the others. We recommend 14 trips to be divided according to the respective needs.

Proposal No. 3 by J. Marton “Precision X-ray spectroscopy of kaonic hydrogen isotopes (SIDDHARTA), and Proposal No. 7 by F. Sirghi “Hadronic atom research at Dafne-Siddharta”

Both experimental proposals concern SIDDHARTA which is actually running on DAFNE as main user until fall of 2009. The experiment has therefore to be supported as full as possible. However small cuts are necessary for lack of funds. We propose therefore;
Proposal No. 3 (Marton) 200 days and 17 trips
Proposal No. 7 (Sirghi) 420 days and 10 trips

 

Examination and selection of proposals for BTF

Proposal No.1 by V. Angelov “A Linac-based neutron source for time of flight measurements”

In the past the group applied for two projects and is refusing to justify their activity at BTF despite repeated requests. The present proposal which refers to the past activity does not contain any element of report, so it can not be recommended.

Proposal No. 4 by J. Ciborowski “Study of cluster shapes in the Mimosa -18 pixel matrix”

The group has already worked successfully at the BTF. The present proposal is well formulated and worthwhile to be executed. The request for 46 days ad 3 trips is accepted.

Proposal No. 5 by D. Bosnar “AMADEUS” Scintillating Fibres Trigger System”

The R&D activity foreseen in this project consists of three stages.
The first one is to be performed in the Department of Physics in Zagreb, testing a system of scintillating fibres and Si-photomultipliers.
The second stage will be performed at LNF using specific electronics and detectors not available in Zagreb.
The third phase consists of tests to be performed at the BTF at LNF.
This evaluates to 10 man days at LNF for the tests and 20 man days for the beam test at BTF which leads to overall 30 man days for each researcher and one trip each. So totally 60 days and 2 trips are recommended.

Proposal No. 6 by D. Dauvergne “Search for observation of an internal clock or of Zitterbewegung in an electron channelling experiment-Setup of a channelling experiment at BTF”

The experiment is aimed at searching for an internal clock or for a Zitterbewegung of the electron by a channelling study in thin Si-crystals.
The USP identified two phases:
(i) A preparational phase in which a close collaboration with the BTF group is established and all the beam parameters and the experimental set up are defined.
(ii) In a second phase a test experiment should follow.
For this reason the USP considers to assign for the first phase 80 man days and 14 trips.
