We present a study of the gain dependence on temperature in several different silicon photomultipliers. This work was motivated by the goal to determine design options for an power supply regulator that has the capability to adjust the bias voltage with changing tempera...

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...

Abstract Precision machines like electron-positron-colliders and b-factories demand for low material budget and high position resolution when it comes to particle tracking. A low material budget can be achieved by using thin double-sided silicon detectors (DSSDs) and li...

The paper describes the status of the laser-based alignment-system for the luminosity detector, LumiCal, taking into considerations the conditions of the International Large Detector in the International Linear Collider project. The design of the system comprises two pa...

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...

An 80x80 pixel ASIC for connection to CdTe detectors for spectroscopic X-ray imaging has been designed at the Rutherford Appleton Laboratory. The 20mm x 21.4mm ASIC is intrinsically 3-side butt-able when bump bonded to a 20mm x 20mm detector. The 4th edge has readout st...
