Beam tests of a CCD tracker for vertex detector application
نویسندگان
چکیده
We have studied the performance of a CCD tracker using minimum ionizing particles (MIP’s) from KEK PS beam line. The detector consists of three layers of CCD sensors manufactured by Hamamatsu Photonics, which suppress the dark current at surface by one order of magnitude compared with that of the conventional ones. We have observed MIP’s can be detected with sufficient signal to noise ratio even up to +5◦C. The position resolution as well as the detection efficiency of this detector are also given.

Full Simulation Studies of the Silicon Tracker for the Linear Collider Detector ∗
A central tracker based on silicon microstrip sensors has been envisaged for the e + e − linear collider experiments. A full simulation program based on GEANT4 has been developed to study performance of the tracker. We report some preliminary results obtained using this program. The use of silicon microstrip detectors as precise tracking devices in colliding-beam experiments has been well estab...

The goal of the EUDET project is the development and construction of infrastructure to permit detector R&D for the International Linear Collider (ILC) with larger scale prototypes. It encompasses major detector components: the vertex detector, the tracker and the calorimeters. We describe here the status and plans of the project with emphasis on issues related to data acquisition for future tes...

The Tevatron at Fermilab is at present the world’s highest energy particle accelerator. After extensive refurbishments, data taking for Run II started in 2001, and by the end of 2003 over 200 pb of usable integrated luminosity had been accumulated by each Collider experiment, double the total for Run I. In preparation for Run II, the CDF detector also underwent an extensive upgrade. Of special ...
متن کاملThe BaBar Silicon Vertex Tracker: Performance and Radiation Damage Studies
The BaBar Silicon Vertex Tracker is a five layers, double sided AC-coupled silicon microstrip detector operating on the PEP-II storage ring at the Stanford Linear Accelerator Center. The performance of the SVT after 4 years of running is described. Results from radiation hardness tests are presented and the implications of the absorbed radiation dose on the SVT lifetime are discussed.
