      • CM1 transport timeline in April - SAS and area around buffer zone free by Friday 11th of April
      • ISOLDE Hall cooling water (27 degrees users Low E side) will be turned off on Wednesday 18/3 until further notice. Small loads (several kWs) can run without full system operational - load to be defined. --> contact Erwin
      • Crane blocked Wednesday 18/3 until Friday 20/3 lunch time
      • Friday 20/3 both route Democrite and Rutherford will be blocked, route Rutherford remains blocked until mid-April at least.
      • A lot of craning activities at the end of next week: LHe for ISOLTRAP on Wednesday 25/3 + craning of laser tables + Intertank
      • Modified parking situation next to 170 next week, please respect the signage

      Safety announcements 5m

      Dear all,
       
      A short update following our checking of extension leads and plugs this morning. 95% of what we found was excellent, appropriately sized cables well connected. The remaining 5% of cables we checked had some issues such as:
       
      1. Cables undersized for the circuit breaker. As a rule of thumb, the minimum cable cross sections for the phase, neutral and earth conductors in extension leads and supply cables should be:
        1. 10A : 1.5mm2
        1. 16A : 2.5mm2
        1. 32A : 6 mm2
      2. PXL_20260316_094849233.jpg These 32A plugs are not connected to 6mm2 cables, replacement required.
      3.  
      4. Poorly terminated cables - strands of cable not inside the connector, strain relief not connected to the sheath of the cable (see photos), terminals not tightened (!).
      5. PXL_20260316_104419605.MP.jpg The strain relief has been put on the conductor insulation, not on the outer sheath. 
      6. PXL_20260316_102452992.jpg The conductor was inserted into the terminal, but not tightened. 
      7.  
      8. Overloaded cables - this is what happens if you don’t follow the rules in 1. This could have started a fire.
      9. PXL_20260316_092009704.MP.jpg
      10.  
       
      Cables that were poorly terminated have been fixed (about 10 in total). Cables that are undersized or have been overloaded have been marked for removal (purple tape) and the plugs removed.
       
      In general we didn’t plug them back in after our intervention, to prevent unwanted restarts of vacuum pumps etc. so please check your setups.
       
      The following zones were not inspected this time, either by prior agreement or because things were powered on:
      CRIS
      IDS
      Miniball
      ISS
       
      I’ll contact you individually to schedule a check when it is convenient.
       
      Best regards,
      James

      Title: Upgrade of Data Acquisition System for VITO
      Speaker: Jakub Kaszowski (CERN)
      Abstract: Quick overview of planned upgrades to the DAQ that are meant to solve potential pile up issues at high count rates. The proof-of-concept simulation shows promising results using deconvolution algorithm.
