Task 8.2.2Test beam infrastructure in FrascatiG. Mazzitelli on behalf of LNF, Ferrara & Perugia INFN structure.

AIDA kick-off meeting, CERN 16-18 February 2011

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

The DANE BTF

The BTF is a e/e test-beam facility in the Frascati DANE collider complex

BTF

high current Linac: 1 500 mA e 100 mA e, 1 - 10 ns pulses, at least 107 particles

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
