  4. Status of EHNL • Beam provided to scheduled Users • T7 (Irradiation1) and T11 running • T10 commissionned up to 7 GeV/c • Hardware, Software • Power supplies : OK • Controls (Partial PPM, New Working Sets, ...) : OK • Instrumentation (SECs, Telescopes, MWPCs) : OK • Image Digitiser : eagerly waiting for operational device • Problems still pending in the area • T10 radiation shielding • Flanges to be mounted in T9 and T7 • Cerenkovs counters to be installed in T10 and T7 • Remaining problems with the beam • Strong low frequency ripple in the spill • Improve beam quality for DIRAC D.
