Additional detector electronics components are required for detector testing and validation activities. These additional items are intended for testing purposes and will allow such activities to be carried out without risking damage to, modification of, or depletion of the components procured under the original agreement that are designated for delivery to FAIR GmbH as part of the project. The purpose of this amendment is therefore to acquire additional units of the same equipment covered by the original agreement in order to support detector testing activities while preserving the integrity and availability of the supplies intended for the final installation and delivery. Amendment to the Procurement Agreement, “VMM3a/SRS readout electronics for the gas detector” signed on 29.10.2024. TED Notice number 572747-2024.
