DA Phi NE monitored by FINUDA

The FINUDA spectrometer, devoted to hypernuclear physics and installed on the DAΦNE two rings collider at the Laboratori Nationali di Frascati, is able to monitor the relevant machine parameters, as luminosity, collision vertexes, c.m. energy and transversal momentum boost, during the process of data taking to study hypernuclear physics without affecting it. The collider parameters relevant to optimize the machine performances to the needs of the experiment are measured both on-line and offline in a run-to-run basis, in an efficient, redundant way, allowing the continuous extraction of reliable and cross-checked information on the machine working conditions.
