The LHCb Vertex Locator Replacement Detector - Electrical and Thermal Performance Studies

This document describes the characterisation of the performance of the replacement detector for the LHCb Vertex Locator. Tests were performed at CERN on the fully assembled detector halves. Included are results of tests of the (i) intrinsic noise on the sensors, (ii) their IV curves, (iii) thermal performance and (iv) various tests associated with the Beetle readout ASIC. A comparison to the current detector is also given.
