Collaborating countries | Italy, Russia, USA, Brazil, Japan |
Number of authors | 71 |
Number of PhD students | 6 |
Location/Infrastructure | Laboratori Nazionali del Gran Sasso |
Funding agencies | Mainly INFN (Istituto Nazionale di Fisica Nucleare), INR (Institute for Nuclear Research, Russian Academy of Sciences, Moscow, Russia) |
Scientific goals | Observation of neutrino bursts from Gravitational Stellar Collapses. The detector sensitivity allows to monitor the entire Galaxy. |
Design | LVD is an array of 840 liquid scintillator counters for a total sensitive mass of 1000 tons. |
Present status (R&D, construction, data taking, closed) | LVD is successfully running in its final configuration from 2001, with a duty cycle > 99%. |
Most relevant results | No evidence has been found for neutrino burst from gravitational stellar collapses (GSC) in the Galaxy since 1992. the resulting upper limit to the rate of GSC at 90% c.l. is 0.2 event/yr. |
Perspective: - total cost, status of funding - merging with other projects - close R&D relations to other projects - coming relevant reviews - branch points | LVD is totally founded. Review to the Gran Sasso Scientific Committee and to the funding authorities twice per year. |
Which relevant results are expected, and when | It will furnish, in occasion of the next galactic gravitational collapse, important information regarding: collapse dynamics, explosion mechanism, neutrino features. It will monitor the CNGS neutrino beam. |
Most actual information - web page - recent transparencies available on the web - recent results in journals or on preprint server. | http://www.lngs.infn.it/ http://www.bo.infn.it/lvd/ CNGS beam monitor with the LVD detector.
