We propose an analytical method for pulse height correction to enable a global energy spectrum and to restore uniformity of signal asymmetry used for extraction of depth of interaction (DOI) information in PET detectors with dual-ended readout configuration. The method is based on empirically modifying the pulse heights obtained from two ends of crystals to correct for non-linear dependency of light...
The design of a full integrated electronics readout for the next ILC ECAL presents many challenges. Low power dissipation is required, and it will be necessary to integrate together the very front-end stages with an analog to digital converter. We present here a 12 bit 30 MHz analog to digital converter using a pipelined architecture. It is composed by ten 1.5 bit sub-ADC with a final 2 bit flash...
An intensity modulated fiber-optic position sensor, based on a fiber to bundle coupling and a readout system using a CMOS image camera together with fast routines for position extraction and calibration, is experimentally demonstrated. Further, a simulation of the complete sensor system setup is made, and possible sources of error are analyzed experimentally. Our analysis indicates the theoretical...
