This document provides an update to the Technical Design Report for the Electromagnetic Calorimeter of the PANDA Experiment. The original TDR was published in August 2008 (RE-TDR-2008-001). The document was sent to the ECE. The answers to their questions are given in the second document.

This document presents the technical layout and the cost assessment for the infrastructure of the PANDA experiment, comprising the following major items: - Supports: Mechanical structures to support the experimental setup, fixed and removable platforms to house equipment and to assemble the experiment, including staircases, ladders,fences, racks and related tools. - Supplies: Distribution systems for electrical power, grounding, fluids and gases. Based on this, the current integration planning and the installation procedure are described. UPDATE July 3: Updated version v1.0 submitted to external referees. UPDATE August 28: Updated version v2.0 for inspection by the PANDA CB before submission to ECE. UPDATE September 14: Version v3.0 for submission to FAIR ECE. Bibliographies completed.

This document describes the technical design and the expected performance of the Endcap Disc DIRC (EDD) for the PANDA experiment. The EDD will provide particle identification for charged hadrons with momenta up to 4 GeV/c in the forward region in the polar angle range of 5° to 22°. The proposed detector is a new development utilizing special focusing elements and highly segmented MCP-PMTs to allow a very compact design. The relevant components have been tested individually and as a joint system. According to our studies the final EDD will provide π/K separation of more than 3 standard deviations over the specified phase space. This is the final version submitted to ECE in August 2018.
