•Magnet: most of the time
•Particles: 2-3 days muons , if possible. 50-100 Hz sufficient (limited by DAQ rate). The rest can be hadrons, from low to very high rates
•Precision tracking and behaviour of the resistive coverlay.
•We need to scan the detector (move frequently) for homogeneity studies. Most data to be taken with T2K gas (ArCF4Iso) but would be nice if a part can be Ar+5%Iso
•Need to install the box on a small lift table and secure it
•Optical fiber, SHV, gas cable already installed
•We also plan to contribute to the RESIST test organized by S. Aune and F. Kunne next to our setup in the magnet
