Prototype Si microstrip sensors for the CDF-II ISL detector
نویسندگان
چکیده
Prototype Si microstrip sensors for the CDF-II ISL were fabricated by Hamamatsu Photonics and SEIKO Instruments using 4A technology. The sensor is AC coupled and double-sided forming a stereo angle of 1.2073. The strip pitch is 112 lm on both sides. The main di!erences between the two manufacturers lie on the technologies of passivation and the structure of coupling capacitors. We describe the design of the sensor and evaluation results of the performance. The evaluations include the total and individual strip currents and interstrip capacitance measured before and after 60Co c irradiation. ( 1999 Elsevier Science B.V. All rights reserved.

The Intermediate Silicon Layers Detector is presently being built as part of the CDF upgrades to prepare for the next Tevatron data taking run, scheduled to start in the year 2000. The ISL will be located in the radial region between the Silicon Vertex Detector and the Central Outer Tracker. It will add tracking in the forward region and signi cantly improve tracking in the central region. Toge...

A new silicon microstrip detector was designed by the CDF collaboration for the proposed high-luminosity operation of the Tevatron pp̄ collider (Run IIb). The detector is radiation-tolerant and will still be functional after exposure to particle fluences of 10 1-MeV equivalent neutrons=cm and radiation doses of 20MRad. The detector will maintain or exceed the performance of the current CDF silic...
