1 Testing Novel TOF Detectors @ ELBE
STATUS REPORT F. Dohrmann, E. Grosse, K. Heidel, B. Kämpfer, R. Kotte, L.Naumann Forschungszentrum Rossendorf Institut für Kern- u. Hadronenphysik September 2004

2 Radiation Source ELBE

3 Beam Parameters Energy 20 MeV (40 MeV in 2005) Currents up to 1 mA
Micro beam structure: Standard mode: <10 ps bunches in 77 ns intervals (13 MHz) Intervals may be digitally sparsified (2,4,…256) or shortened up to 260 MHz (factor of 20) Macro beam structure smallest repetition rate 38 ms No multi user mode possible

4 Beam Parameters scattering chamber Ideal scenario: direct use of very low intensity primary electron beam (  103 e- /s) However: beam diagnostics currently limits controllable beam current to  1 mA ( ie  1013 e- /s)  scattering experiment 10 nA up to 100 nA on thin target foil or diamond. Detect scattered e- to study background and intensities. Simulations with FLUKA and Geant4

15 Background Studies First measurements in summer 2004

16 Outlook Time reference with scintillators Prepare RPC tests
Fast reference scintillators with XP2020 PMTs Prepare RPC tests contacted RPC developers at Coimbra, GSI and INR Moscow Hardware installation First RPC prototype obtained for testing Gas system installation (iso-Butane, SF6, R134a) for RPC tests in cave and lab Readout electronics, triggermodules, RIOs etc. In addition will setup a dedicated cave for testing in 2005
