1. General Introduction to IFR
W. Baldini, INFN-Ferrara
XIV SuperB General Meeting, Frascati Sept.27 – Oct

2. Overview Introduction to the IFR News since Elba Meeting
Ongoing activities
Goal for the meeting and plans for the TDR
Other IFR contributions

3. The IFR Baseline Detection Technique
Magnet Flux Return instrumented to detect Muons and KL
BaBar-like detector with hexagonal barrel and two encaps
Plan to re-use BaBar IFR structure, adding iron to improve μ-ID
Scintillator as active material to cope with higher flux of particles
Minos-like scintillator bars readout through WLS fibers and Silicon Photo-Multipliers
8-9 active
layers
Endcap
Barrel μ

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. Active Layers Main components
SCINTILLATORS: produced by extrusion at FNAL in the FNAL-NICADD facility
thickness: 1.0cm for TDC-RO
2.0cm for BI-RO
coated with TiO2 (co-extruded)
WLS FIBERS: two types under test
Saint-Gobain BCF92: fast (decay time 2.7ns) but limited light yeld
Kuraray Y11: slower (decay time ~ 9 ns) but ~20% higher light yield
SiPM: produced in Trento by IRST-FBK
1.2x3.2 mm2 to match 3 fibers ϕ=1.0mm
1.4x3.8mm2 for ϕ=1.2mm fibers
array of 3 round SiPM ϕ=1.4mm

6. The Prototype
Active Layers
(Pizza Boxes)
A full scale prototype is being developed to measure on beam the performances and test different readout options:
Muon-ID for different iron-scintillator configurations
Detection efficiency
Time resolution
More detailed description in the next talk

7. Simulations μ 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)
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

8. Goal for this meeting
Review the status and the achievements for all the ongoing activities
Particular focus on:
Prototype finalization and local tests (cosmics, source)
Detailed planning and coordination of the the testbeam
Analyze the TDR preparation process and
Organize the medium term activities
