Status of RPC Commissioning RE+3 pre-commissioned RE+2 pre-commissioned RE+1 pre-commissioned RE-1/2 pre-commissionedMissing Front-End functional and read-out test and

cooling test. Few gas leakages to be fix and understood

Commissioning needs a clear resource allocation and commitments

Tower Test

On going Tower Test on Near Side Half Wheel +1

Step 1) Cabling: connectivity, CCU chain

Step 2) LV up: grounding and functionalities

Step 3) HV up: stability

Step 4) Data Acquisition: performance, full chain

Use of the MTCC set-up in Green and Balcony Barracks
