Scientific goalsObservation 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.
- total cost, status of funding
- merging with other projects
- close R&D relations to other
- 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.
