	The demands on hardware for control and data acquisition at large-scale research organizations have increased considerably in recent years. In response, modular systems based on the new MTCA.4 standard, jointly developed by large Public Research Organizations and industrial electronics manufacturers, have pushed the boundary of system performance in terms of analog/digital data processing performance, remote management capabilities, timing stability, signal integrity, redundancy and maintainability. Whereas such public-private collaborations are not entirely new, novel instruments are in order to test the acceptance of the MTCA.4 standard beyond the physics community, identify gaps in the technology portfolio and align collaborative R&D programs accordingly. We describe the ongoing implementation of a time-limited validation project as means towards this end, highlight the challenges encountered so far and present solutions for a sustainable division of labor along the industry value chain.

TUCOCA09	Klystron Measurement and Protection System for XFEL on the MTCA.4 Architecture	high-voltage, LLRF, vacuum, FPGA	937

	The European XFEL free-electron laser is under construction at the DESY. The driving engine of the superconducting accelerator will be 27 RF station. Each of an underground RF station consist from multi beam horizontal klystron which can provide up to 10MW of power at 1.3GHz. The XFEL should work continuously over 20 years with only 1 day per month for maintenance. In order to meet so demanding requirement lifetime of the MBK should be as long as possible. In the real operation the lifetime of tube can be thoroughly reduced by service conditions. To minimize the influence of service conditions to the klystrons lifetime the special fast protection system named as Klystron Lifetime Management System (KLM) has been developed, the main task of this system is to detect all events which can destroy the tube as quickly as possible, and then stop input power to the tube and send signal to stop HV pulse. The tube recovery procedure should depend on the kind of events has happened. KLM is based on the standard LLRF uTCA system for XFEL with additional DC channels. This article gives an overview of implementation of measurement and protection system installed at klystron test stand.
