7. OPERA Coll.Meet. October 2002Luca Stanco - Padova7 Final design reached (2.6 cm pitch in x-view, 3.5 cm pitch in y-view) Full double layer (x any view) (final) prototype ordered at Pol.Hi.Tech To be ready in November To be tested at LNF in December Started procedure for tendering to be ended in January-February 2003 STRIPS

8. OPERA Coll.Meet. October 2002Luca Stanco - Padova8 RPC PRODUCTION Production plan for OPERA: October 1rst Delayed 1 month in cooperation with ARGO  November 4th Bakelite planes ready at PanPla company. To be sent to General Technica (this week) 500 chambers are necessary for one Spectrometer Each Spectrometer has to be installed, together with RPC’s in 6 months

9. OPERA Coll.Meet. October 2002Luca Stanco - Padova9 ELECTRONICS Front-End card (2nd prototype): - 64 channels (final, 16 ch for prototype) - differential receivers exaustively studied (good response until 5 mV) - Z in = 100  - input polarization for at least two samples - threshold tunable 0 – 300 mV for groups of 16 channels - mask single input - digital test-in - FastOR over 16 channels 1  s long, TTL output at 50  - generation of interrupt on the FastOR - external trigger/gate for all the channel. TTL output at high Z - double buffer for the events - VME-like read-out … under test with RPC in Padova

10. OPERA Coll.Meet. October 2002Luca Stanco - Padova10 Backplane: - for Eurocrate 6U - 19 FE cards of 64 channels each - in the 2 free positions a power supply “switching”-like 250 W, +3.3 V, +5 V, ±12 V, standard PCI …offers from company on the way …possibility to build the prototype in Padova under investigation FE 64 channels card: - final design under going Strip-connectors-FE-cards: - Impedence adapters - under definition at LNF Cabling: - ready to buy High Voltage system: - under development at LNF

11. OPERA Coll.Meet. October 2002Luca Stanco - Padova11 System test at Gran Sasso very well in time and succesfully set-up RPC pre-production will allow complete test of the system for end of August Many tests on the full scale RPC prototypes -> good results Mechanics on the way on. First prototype for installation end of July Electronics well suited. Need FE – DAQ integration. More people are coming Production for OPERA at General Technica tight but acceptable. of June 2002 … end of September Naple not yet true … at October 2002
