	Funding: This work is supported by the European Atomic Energy Community's (EURATOM) H2020 Programme under grant agreement n°662186 (MYRTE project). The MYRRHA project aims at the construction of a new research reactor in Mol (Belgium) to demonstrate the nuclear waste transmutation feasibility with an Accelerator Driven System (ADS). In its subcritical configuration, the MYRRHA facility requires a proton beam with a maximum power of 2.4 MW (600 MeV - 4 mA). Such a continuous wave beam will be delivered by a superconducting linear accelerator (linac) which must fulfil very stringent reliability requirements to ensure the safe ADS operation with a high level of availability. The linac injector will be composed of: a proton source, a low energy beam transport line (LEBT), a 176 MHz RFQ and CH-DTL cavities. The LEBT prototype has been built and is presently installed and operated at LPSC Grenoble (France). An experimental program, to optimise the tuning of the line, the beam transport, and to study the space charge compensation mechanism, is in progress. We here review the main achievements of the LEBT commissioning. Experimental results will be presented and discussed, in particular the influence of the residual gas (type and pressure) on the beam dynamics.

	The approach to the MYRRHA Control System (CS) development will be described. The effort, time and resources needed to develop the control systems are often underestimated by a significant factor. This brings unnecessary setbacks to the projects. Understanding CS requirements at an early machine conception stage is paramount for adequate CS design. Awareness of sheer project size and interdisciplinary complexity is imperative for successful project execution. In the first part of the paper the MYRRHA roadmap, milestones, status and its future needs will be presented with an emphasis on the phased approach leading to the 100 MeV program. The second part of the paper will give the status of the MYRRHA CS development within this phased approach. Best practices for coherent integration will be discussed. The CS should provide a flexible framework for the integration of devices. Interfaces and services need to be defined early in the integration process, and the number of different interfaces and platforms should be kept to a minimum. The implications of the choice of technologies and of SW development processes on the overall reliability and availability have to be established.
