Beam telescopes in test beam area


The DESY II Test Beam facility currently provides one ALPIDE-based and two EUDET-type beam telescopes:

  • DATURA at TB21
  • ADENIUM at TB22 (ALPIDE-based)
  • DURANTA at TB24

EUDET-style beam telescopes are based on six layers of 50μm thin MIMOSA26 sensors, monolithic pixel sensors with a small pitch of 18.4μm, optimal for achieving an excellent track pointing resolution at the center of the telescope despite the moderate beam momenta at DESY II (≤ 6.3GeV). The active sensor area is approximately 1cm x 2cm.

The ALPIDE-based telescope (ADENIUM) is based on six layers of ALPIDE sensors (also 50μm thin, pitch of 29.24μm/26.88μm, active area of ca. 3cm x 1.5cm).

All three telescope setups include a trigger logic unit, the AIDA TLU, and trigger scintillators.

(Please note that the AIDA TLU's  predecessor, the EUDET TLU, is considered a legacy product by the team at DESY. We do not maintain or offer support for it. Few partially broken units may still be available.)

Dedicated control PCs are available in each test beam area and in each control hut (see network infrastructure).

The pre-installed DAQ sofware famework is EUDAQ2. Default scripts for standalone telescope operation are available. DUT integration is generally considered to be the users' responsibility but we'll do our best to help if you contact us.

(Also here, please note that we do not support EUDAQ(1) anymore. You can of course still install it yourself.)
