The goal: • Make the Optimum Trigger (OT) work for the online data-taking of CUORE: Ø the OT algorithm is demanding in terms of computing resources, therefore it needed different improvements and tests (both offline and online) to meet the goal;

Analysis of data acquired during calibration with both OT and DT Are we able to get the same events tagged by DT at high energy? • from the comparison of the DT and OT energy spectrum, we can conclude that OT is performing very well; Derivative 239 ke. V 338 ke. V 583 ke. V 911 ke. V 969 ke. V 2615 ke. V OT Single trigger required • Since OT has lower thresholds, we recognize more pile-up, so there are less events in energy spectrum from OT 6

We are able to reconstruct the characteristic Te X-rays • Fit with an eight Gaussian line shape plus linear background: Ø Relative intensities and positions of Ka 2, 3 fixed w. r. t. Ka 1; Ø Relative intensities and positions of Kb 2, 3, 4, 5 fixed w. r. t. Kb 1; Ø Same width for all gaussians; 7

• Preliminary OT energy thresholds in CUORE: Ø energy threshold defined as the energy at which events are identified with 90% of efficiency; OT DT 8

Conclusions: • OT is now implemented in CUORE for the online data-taking since May 2018; • The trigger allows to lower the energy thresholds: Ø analyses at low energy can be performed (Dark Matter, Axions, Supernova neutrino, low energy radioactivity); Ø better rejection of background events in standard analyses like 0 v.
