The concept of a tile hadron calorimeter (HCAL) for the International Linear Collider (ILC) has been developed. A major aspect is the improvement of the jet energy resolution by measuring details of the shower development and combining them with the data of the tracking...

<jats:p>The Large Prototype TPC at DESY, Hamburg, was built by the LCTPC collaboration as a testbed for new readout technologies of Time Projection Chambers. Up to seven modules of about 400 cm<jats:sup>2</jats:sup> each can be placed in the endcap. Three of these modul...

A prototype time projection chamber with 26 cm drift length was operated with a short-spaced triple gas electron multiplier (GEM) stack in a setup triggering on cosmic muon tracks. A small part of the anode plane is read out with a CMOS pixel application-specified integ...

KLauS is an ASIC produced in the AMS 0.35μm SiGe technology to read out the charge signals from silicon photomultipliers. Developed as an analog front end for future calorimeters with high granularity as pursued by the AHCAL concept in the CALICE collaboration, the ASIC...

Detector-plane prototypes of the very forward calorimetry of a future detector at an e+e- collider have been built and their performance was measured in an electron beam. The detector plane comprises silicon or GaAs pad sensors, dedicated front-end and ADC ASICs, and an...

Luminosity upgrades are discussed for the LHC (HL-LHC) which would make updates to the detectors necessary, requiring in particular new, even more radiation-hard and granular, sensors for the inner detector region. 1Corresponding author. c CERN 2014, published under the...

DESY Hamburg operates a test beam facility with three independent beam lines at the DESY II synchrotron. It is world-wide one of very few facilities providing test beams in the GeV range. To this end, it offers electron/positron beams with user-selectable momenta from 1...
