  1. Task 8.2.2 Test beam infrastructure in Frascati G. Mazzitelli on behalf of LNF, Ferrara & Perugia INFN structure. AIDA kick-off meeting, CERN 16-18 February 2011

  2. Beam Test Facility(BTF) Infrastructure The Frascati BTF infrastructure is a beam extraction line optimized to produce electrons, positrons, photons and neutrons mainly for HE detector calibration purpose. The aim of the task 8.2.2 is to improve and further qualify the BTF facility B. Buonomo, L. Foggetta, G. Mazzitelli, L. Quintieri & P. Valente

  3. BTF • high currentLinac: • 1 - 500 mA e- 100 mA e+, • 1 - 10 ns pulses, at least 107 particles The DAFNE BTF The BTF is a e-/e+test-beam facility in the Frascati DAFNE collider complex Need to attenuate the primary beam: • Single particle regime is ideal for detector testing purposes • Allows to tune the beam intensity • Allows to tune the beam energy

  13. 8.2.2. second milestone INFN Perugia & UiB – Ref. C. Cecchi LYSO calorimeter … LYSO calorimeter prepared as a SuperBprototypeto provide a map of beam energy in various beam operating parameters. AIDA-WP8

  14. LYSO calorimeter to study the dependence of the beam energy and resolution on the beam operating parameters Prototype mechanical structure has been designed and built Front-end electronics has been designed and developed 6 crystals inserted in the structure and with two different readouts (PiN and APD), with the developed FE electronics have been tested at the BTF.

  16. 8.2.2. third milestone INFN LNF - Ref F. Murtas GEM tracker status… GEM chambers for monitoring the beam position and the beam width with a resolution of about 300 μm. For tests of tracking detectors a beam tracking telescope will be built based on GEM providing a spacial resolution of <100 μm in one view. AIDA-WP8

O(10 mrad) development: limitation due to minimal pad dimension 300mm and design and implementation of high density front end electronics x z compact design: fpga basedethernet/opt/usb output

  19. 8.2.2. fourth milestone INFN Ferrara & LNF - Ref R. Calabrese Multi purpose DAQ… A multi purpose DAQ able to acquire, store and synchronize beam parameters and data with experiments DAQ. AIDA-WP8

  20. Multi purpose DAQ • Integrate most common device – ADC/TDC/SCALER, etc (BTF and LNF electronic pool ) • Integrate BTF beam diagnostics (calorimeters, profile monitors – scintillating fiber & Si chambers, photon tagging, neutrons monitors) • Tag & synchronize data with hosted experiments DAQ front end VME – DAQ labview & C cins based GUI - on line beam monitor e- spectra XY beam sci or Si ch-profile

  21.
