we inform you that the Program Advisory Committee (PAC) of the Laboratori Nazionali di Legnaro (LNL) of INFN will meet on July 10 – 12, 2023.
The PAC will select experiments to be performed with the Tandem, CN and AN2000 accelerators during the period September – December, 2023.
The deadline for the submission of proposals is June 2nd, 2023.
Status of the Accelerators
The Tandem accelerator and the CN and AN2000 accelerators will be operational for the next semester. No ALPI or PIAVE-ALPI beams will be available.
The Tandem accelerator can be operated at terminal voltages up to 14 MV. The CN accelerator will be limited to terminal voltages up to 5.5 MV. The AN2000 accelerator will be available in self-service mode.
An updated list of available Tandem beams and energies is accessible here.
We remind that the energies and intensities reported in the table are indicative ones: in selected cases higher energies may be achieved at the expense of beam intensities. The proponents are encouraged to contact PACbeams@NOSPAMlnl.infn.it for further details.
Useful information about the CN and AN2000 accelerators may be found here.
Only web-based submissions are accepted. Please, use the on-line submission form
You are encouraged to use the LaTeX or Word template files for the abstract and body of the proposal, available on the Web pages. The maximum length of the abstract has to be restricted to one page and must contain:
-the title of the proposal;
-the accelerator complex to be used (e.g. Tandem, CN, AN2000)
-the experimental setup and/or the beamline for which the experiment is proposed;
-the name(s) of the spokesperson(s);
-the names of the Group Leader In Matter of Safety (GLIMOS);
-the list of all the authors and their affiliation;
-a brief summary of the proposal.
The body of the proposal does not contain the abstract page and has to be strictly limited to a maximum of 5 pages (12pt fonts) – tables, figures and references included.
The proposals should include the scientific motivation of the experiment, technical details of the proposed measurement – i.e. the description of the instrumentation needed, quantities to be measured and related precision – and the number of days of beam time requested based on count-rate estimates. A detailed schedule for each measurement run should be included, stating the ion species, the energy or range of energies, the beam current, and the number of requested days. For continuation experiments, a brief summary of the status of activities performed in previous periods is expected to be reported.
Once you have submitted the “Beam Time Request” a report page on inserted data will be displayed and you will be asked to fill in also the on-line “Targets Request Form”. The Targets Request form may be filled in more times by clicking again the “Targets Request Form” link in the report page.
After the submission, you will receive an e-mail message confirming that your request has been registered. Do not delete the message, because it also contains a password needed for later modifications.
Technical Review of the Proposals
After the submission and before the PAC meeting, the technical feasibility of the proposals (in terms of beam availability, intensity, energy, target, status of the accelerators, readiness of the experimental setup, radioprotection limits, accident safety and prevention) will be reviewed by an internal LNL committee.
The spokespersons will be notified about any issue found by the technical evaluation of their proposals about 7 days before the PAC meeting.
Oral presentation of the proposals at the PAC meeting (10 minutes + 10 minutes discussion) may be required both to new and continuation experiments and should contain previously obtained results, if applicable.
The PAC meeting will be held in person. Spokespersons are requested to present in person their proposals.
