1. PAN Accurate Monitoring 1.HAPPEX Analysis Strategy 2.Code 3.Main features 4.To come 5.Demo (beta version) HAPPEX Collaboration Meeting 7 Dec, 2002. Antonin Vacheret CEA/SPhN, Saclay.

2. HAPPEX Analysis Strategy IDEA : Split task to make the feedback control fast, simple and robust. - Prompt and monitoring analysis runs separately. -> If crashes occurs : No effect on the runs. - Technically possible to have 3 ET clients running at 30 Hz and until 200 Hz without dead time in the analysis ( No dead time for the DAQ). Coda data stream PANAM Pan Feedback Analysis Pan Prompt Analysis ET Clients : HAPPEX Collaboration Meeting 7 Dec, 2002 Antonin Vacheret CEA/SPhN Saclay.

3. CODE -Main class handle the GUI (ROOT based) -Reuse of Pan code (analysis task) -Multiple threads (sub processes) allow for easier control of the GUI, Pan analysis and display of histograms -Use Pan Data map channels and defined set of plots for each -Add new classes to deal with Stripchart type histograms. HAPPEX Collaboration Meeting 7 Dec, 2002 Antonin Vacheret CEA/SPhN Saclay.

4. Main features -Basic set of Canvas with Stripcharts and histograms (ADCs, BCMs, BPMs, asymmetries, differences, Lumi, detectors…) -Design allows for easy modification (last minute changes always occurs…). -List of all available plots displayed on screen. Instant control of channels individually. -Miscellaneous canvas for customized monitoring HAPPEX Collaboration Meeting 7 Dec, 2002 Antonin Vacheret CEA/SPhN Saclay.

5. To come… - Test in real conditions during spin duality/GDH (Online tests starting next week) -Easy change of display configuration between runs. - Feedback control canvas. - Miscellaneous canvas for customized monitoring. HAPPEX Collaboration Meeting 7 Dec, 2002 Antonin Vacheret CEA/SPhN Saclay.
