Charge Collection and Capacitance-Voltage analysis in irradiated n-type magnetic Czochralski silicon detectors
The depletion depth of irradiated n-type silicon microstrip detectors can be inferred from both the reciprocal capacitance and from the amount of collected charge. Capacitance-voltage (C-V) measurements at different frequencies and temperatures are being compared with the bias voltage dependence of the charge collection on an irradiated n-type magnetic Czochralski silicon detector. Good agreeme...
متن کاملFluence dependence of charge collection of irradiated pixel sensors
The barrel region of the CMS pixel detector will be equipped with “n-in-n” type silicon sensors. They are processed on DOFZ material, use the moderated p-spray technique and feature a bias grid. The latter leads to a small fraction of the pixel area to be less sensitive to particles. In order to quantify this inefficiency prototype pixel sensors irradiated to particle fluences between 4.7×10 an...
متن کاملCMOS Charge amplifier for liquid argon Time Projection Chamber detectors
1. INTRODUCTION We developed an integrated circuit (IC) for the readout of LAr (Liquid Argon) TPC (Time Projection Chamber) neutrino detectors. These detectors employ LAr simultaneously as massive target and detection medium. The detection of secondary particles produced in neutrino interactions is achieved by collecting, on a system of wires at the sides of the detector, the electric charges f...
متن کاملThe Electric Field in Irradiated Silicon Detectors
The electric eld distribution inside heavily irradiated silicon particle detectors is deduced using observations of particle and MIP signals. In these detectors particle signals are observed for both p and n side illumination even when the detector is only partially depleted . The observations indicate that the electric eld distribution within the detector has the contribution expected from a u...
متن کاملSpace Charge in Ionization Detectors
The effect on the operation of a vacuum diode of a spatially varying distribution of free electrons, commonly called space charge, was first considered by Child [1] and Langmuir [2]. In that example electrons are released from a hot cathode at low velocity, and then drift freely under the influence of the local electric field as modified by the drifting electrons. In this problem, deduce the st...
