1. IFR Status Report W. Baldini, on behalf of the Ferrara SuperB-Group XIV SuperB General Meeting, Frascati Sept.27 – Oct.1 2010

2. Overview Introduction to the IFR Status of Prototype assembling Software Test beam preparation DAQ and Electronics Conclusions

3. IFR Baseline Detection Technique Plan to re-use BaBar IFR structure, adding iron to improve μ-ID Extruded Scintillator as active material to cope with higher flux of particles Minos-like scintillator bars readout through 3 WLS fibers and Silicon Photo- Multipliers (SiPM) 82 or 92cm of Iron interleaved by 8-9 active layers (under study with simulations and testbeam) Two readout options under study: Time readout (TDC-RO) barrel Binary readout (BI-RO) endcaps SiPM Minos like scintillator bar + WLS fibers

4. Readout Options Time readout Option (TDC-RO): the hit bar gives the first coordinate while the signal arrival time provides the second measure the 2 coordinate at the same time 1ns time resolution  ~ 20cm need TDC readout for each channel relatively simple to be constructed res~20cm Binary readout Option: (BI-RO): the two coordinates are given by two planes of orthogonal scintillator bars: high combinatorial simpler (and cheaper) electronics more complex construction Both option will be tested on beam thanks to a full scale prototype

5. The Prototype Active Layers (Pizza Boxes) The Iron is on Its way to Fermilab Iron: 60x60x92 cm 3, 9 slots for the active layers up to 9 active layers readout together 4 Time Readout (TDC-RO) “standard “ 4 Binary Readout (BiRo) “standard” 4 special modules to study different fibers or SiPM geometry Iron Prototype Active Layer (“pizza box”)

6. Pizza boxes assembling Some pizza boxes during the assembling phase in the Ferrara clean room

7. Labeling and collecting the fibers around the supports Fill with optical glue the embedded holes Fill the machined grooves with optical grease and cover it with stripes of reflecting aluminum (BiRo only) Put double-side adhesive to fix the second layer (BiRo only) Various assembling steps

8. Next and last step: Fiber-SiPM coupling 8 SiPM Fibers The pizza boxes assembling is 90% completed Last step is the coupling of the fibers with the SiPM Will be done as soon as we receive all the sensors (at present we have about a Half) Pizza boxes assembling status If no additional delays in SiPM delivery the assembling will be completed by mid- October Each pizza box will be locally tested with cosmics before shipping to Fermilab

9. SiPM Characterization status Three types of SiPM with different geometry to be tested: 1.2x3.2 mm 2 (type 4020), to be coupled to 1.0mm fibers (3 fibers), total 126 needed, 55 tested 1.4x3.8 mm 2 (type 4380), for 1.2mm fibers, 128 needed, 60 tested array of 3 round sensors:  =1.4mm (type 5550) for both 1.0mm and 1.2 mm fibers, 53 needed, 53 + 5 spare selected 4020 4380 5550

16. A full prototype simulation has been developed: It takes into account the realistic condition of the testbeam (e.g. 18 cm of iron in front of the prototype to stop electrons) It simulates both types of Layers: TDC-RO and BI-RO, for the latter the two layers are simulated separately It allows to move the active layers in different slots, to study the best configuration Bi-Ro TDC-RO Prototype 18 cm of iron μ X and Y separate Layers for Bi-Ro Prototype Simulation

17. Prototype DAQ and ODC status On Detector Control system almost ready Setting up and control of V bias and Thresholds for each channel It allows to work in constant V bias or in constant Gain mode IFR-Prototype DAQ development is Ongoing: BiRo modules readout: first working version available TDC-RO modules readout: in progress ODC control panel DAQ control panel

18. Prototype Electronics status SuperB IFR prototype: 5 layers BI-RO, scintillators 1 cm thick, read in binary mode 4 layers of TDC-RO scintillators 2 cm thick, read in timing mode A total of 12 “IFR_ABCD” boards produced, one for each of the 9 layer + spares ABCD board The redout electronic chain is under test with pulser for the moment As soon as pizza boxes are ready (the first probably next week) real signals readout will be tested Prototype ABCD Boards Crate 2 ABCD Boards Crate 1

19. Conclusions At present our efforts are mainly dedicated to the construction of a prototype to be tested at Fermilab in December The assembling and the related activities are proceeding rather smoothly We plan to complete the assembling and start the local tests by mid-October The planning of the test beam is ongoing, not trivial Is like a small experiment
