Results from the STAR TPC system test

Results from the ALICE-TPC laser calibration system

A cylindrical Time Projection Chamber [1], is the main tracking device of the dedicated heavy ion LHC experiment ALICE at CERN. Each end of the cylinder holds a readout plane which is subdivided into 18 segments in azimuth and two parts in radius (s. fig. 1). Both readout planes thus consist of 18 innerand 18 outer multiwire proportional readout chambers (IROC and OROC, respectively) with catho...

Correcting for Distortions due to Ionization in the STAR TPC

Physics goals of the STAR Experiment at RHIC in recent (and future) years drive the need to operate the STAR TPC at ever higher luminosities, leading to increased ionization levels in the TPC gas. The resulting ionic space charge introduces field distortions in the detector which impact tracking performance. Further complications arise from ionic charge leakage into the main TPC volume from the...

Relationship between Training-Induced Changes in the Star Excursion Balance Test and the Y Balance Test in Young Male Athletes

Background. Dynamic balance is often assessed in athletes using either the Star Excursion Balance Test (SEBT) or the Y Balance Test (YBT). There is evidence that the results for the three common directions are not comparable. Thus, the question is open to debate as to which instrument is better suited to measure training-induced changes over time. Objectives. The aim of this study is to compar...

A DAQ System for Linear Collider TPC Prototypes based on the ALEPH TPC Electronics

Within the international studies of a high energy linear electron positron collider, several groups are developing and testing prototypes for a Linear Collider TPC. This detector is planned to be used as a central part in the tracking system of a detector at such a machine. In this note we describe a DAQ system, which has been developed for the use in tests of TPC prototypes. It is based on ele...
