SiD Status and Plans

Abstract: Recent work carried out in the SiD Consortium is reported. Results have been obtained with the Chronopix version 3 chip, intended for the SiD vertex detector. A test structure is being produced for KPiXM, a CMOS MAPS approach that could be used for the tracker and electromagnetic calorimeter. Tracker sensors are being tested and a new prototype sensor is being planned. A new effort on tracker support structures has begun and first prototypes produced. New studies of the pair background envelope in the beam pipe have been carried out. Electromagnetic calorimeter testbeam data has been analysed and plans are being developed for a full stack prototype. New comprehensive studies of high-rate backgrounds and muons from the beam delivery system have been carried out to determine aspects of the forward region layout. Work has started on alignment and calibration strategies; and progress has been made on a new simulation and reconstruction framework for SiD.
