ERAM status

Conveners: Alain Delbart (Université Paris-Saclay (FR)), David Henaff (CEA), Guillaume Eurin (CEA/IRFU/DPhP), Laura-Iuliana Munteanu (CERN)

1 ERAM production status at Rui's lab

Speakers: Alain Delbart (Université Paris-Saclay (FR)), David Henaff (CEA), Guillaume Eurin (CEA/IRFU/DPhP), Laura Munteanu (CERN), Laura-Iuliana Munteanu (CERN)

- ERAM-46 will be tested today by Antonio. We should have a feedback from him wether or not the HV test in air is ok and if this ERAM needs a cleaning

2 Mesh pulsing

• ERAM-46 cartes du mesh pulsing 8 & 9
• ERAM-39 : should be scanned with FEC cards affected to ERAM-33 : fec 15 & 76

 

This week: scan 39 with FEC 15 & 76

5 ERAM AOB

Speakers: Alain Delbart (Université Paris-Saclay (FR)), Charlotte Riccio (CEA-Saclay (FR)), David Henaff (CEA), Guillaume Eurin (CEA/IRFU/DPhP), Laura-Iuliana Munteanu (CERN)

• Serious problem on the reliabilkity of the mesh connection to GND with the 2 pin connector + jumper
• inspection of all remaining ERAMs must be done to
  • assess the reliability of the 2 pin connector soldering + fixing with glue
  • assess the quality of the contact with the jumper (glue shortening the contact length for instance)
  • after this survey we will decide if we bypass the connector with a wire (what will be done on 3 ERAM of the bottom TPC) on some ERAMs or all of them (the preferred and safest solution)
•
