Platform EPC:

• Ticket open for neons above the platform (Jerome Cantet EN/EL) - in progress/to follow up
• New beamlines depart: RY02 - RY06 'beamlines' from ERD11.06*80 (via ERK3*80) - needs final validation / connection (Nicolas David / Patrick Gallay EN/EL) 
• Scaffolding has been removed last week 
• Remaining cable work will (re)start wk 27 / 29th June (due to non-availabiloity of the cable team (HL-LHC))
• With some delay the commissioning of the new power supplies and controls by OP is expected to start ~20 July
• Nicolas commissioning the controls on the platform done (gateway and power supplies)
• Local circuit-breakers consignation foreseen of the beamlines power supplies on Thursd-afternoon 25th June in the frame of endoscopie verification of the elements convined in the shielding walls between the HRS and GPS sep zones and target area (Stefano Marzari). Request gone out to First-Line
• Modification ex-false floor to be seen with Severin (Erwin)

197 Power supplies consolidation:

• Renforcement of the metal floor structure asap in July (Jordy) if resources are available, alternatively Sept / or via Severin to keep timeline - news?
• EPC to come with a date to empthy the racks
• Old MISTRAL power supply to be moved to 275, but not without a plan (Hanne Heylen / Dave Lunney): consignation done, Andy will remove the AC connections, DC and temp/interlock cables to be disconnected (James Devine) - news? , water tubes to be disconnected (Alex?)

REX/HIE ISOLDE: 

• In the frame of the REX LLRF consolidation the REX LINAC RF cavities chacterization measurements will be carried out by Daniel Valuch and Giampaolo Piccinini on monday-morning 29 June.
• The mixed water is due to no load at a temperature of ~17 C instead of 20 C. Concequences for the characterization measurements to be seen.
• Actions on the REX/HIE list:
  - HIE: replacement prim. pumps CMs, backing & roughing lines - Oct/Nov (after LHC LS high peak work).
  - Modification of the chamber of the XL9GP Quad (last in REX LINAC before CM1/DBox) (Nicolas Thaus TE/VSC). Quad to be taken out for this - to be scheduled with Antony Newborough and transport. - to be done.
  - Removal of the obsolete 9GAP 202MHZ amplifier workaround cables (2015) from the mezzanine/MR-Tof area into the tunnel to the 9GAP structure (~11x) in wk 27 due to lack of EN-EL cable team resources (HL-LHC)
  
  
• REX Low E development:
  - Replacement of the leaking REX mass slits actuator for a bellow type one - decision to be taken on the type (Fredrik in strong favour of the manual version). Alberto would like to have it as a subject of the next SGUI meeting to evaluate both options (manual/remote controlled) and have a decision made through the SGUI on how to proceed.
  
  
• REX EBIS platform modification in the frame of the RILIS project. 30cm of the platform will need to be cut (on the RILIS side)
• Concequences for REXEBIS filling and drifttube & alignment tube (dis)mounting are being addressed (see also last week Cryo / RILIS project discussions on dewar solutions) - Vincent integrating the solutions. Decided to go ahead with the modifications to the platform and implement best filling method later (is solvable, best solution to be chosen once the platform is finished).
• Integration is part of the ICL meetings
  
  
• For installation of the CHROME related cables a scaffodling has been put up along the VITO and over the CAO line around the REXTRAP cage. Work will start wk27 and last ~2 weeks (Rustan/Julien teams).
  
  

• MINIBALL AC power distribution presently through sockets is to be improved and brought up to standard of a semi-permanent installation (ISS side already done)
• News on the 7kCHF total costs between EN/EL and ISOLDE Technical Infrastructure (James)?
  
  
• BI workzone, for HIE (and other) instrumentation, is to be allocated between the XT03 and XT02 beamlines: 2 work benches and test set-up is being installed these days. Network connections to be allocated (J. Tassan-Viol)
• A colection chamber (Juliana Schell) was stored in the BI reserved area and moved to the 'puma' side of the hall.

Separator zones HRS & GPS:

• GPS separator zone scaffolding has been removed last week
• Access this afternoon to the separator zones to review the configuration/setup of the beamgates in the frae of the beam gates consolidation (power supplies and controls, etc.)
  
  

Beamlines:

• A new Rack 50 (BI instrumentation) has been installed with the old one standing in the gLM/GHM area for eaquipment swap ones all is back in place.
• Removal of the remaining shilding block was done. Equipment on the shielding block next to the HRS entrance has been removed. This block as well as reconfiguring of the blocks in the GLM/GHM area is foreseen Wedn 24th (Laura / Transport)
  
  

Commissioning new target heating power supplies 170 HT room:

• GPS heating test will be carried out Friday-morning 26th for which the deconsigation has been requested to First-Line on Thursd-afternoon 25th (16h15). This fits with the IBDRS works and has been communicated.
• Target cooling water and GPS10 sector vacuum will be restarted latest Thursday 25th

Fiber Optics work:

• 2nd phase of the White Rabbit fiber optics installation (Nenad Simic) has been scheduled for wk34 with a VIC on the 12th Aug.

Fume cupboard exhaust GLM/GHM zone:

• Options have been discussed between CV (NIna), Transport (Yann/Filippo) and ISOLDE Tech coordination.
• The crane will need the end stops to be moved forward to avaoid any clash with the airduct going up from the fume cupboard into the ventilation room above
• Larger shielding blocks on the top row will nee dto be replaced by smaller ones so that handling without the crane becomes possible
• The duct will remain dismountable and crane passage above the EPC platform will be verified to allow possible GPS bunker shielding blocks and equiment handling

Ethernet/WiFI 197 & 508:

• in the frame of a change to the power distribution for the starpoints in 197 and 508 there will be short disturbances and cut of the data networks:
• Starpoint 197: Technical Network will not be interrupted, General Purpose and WiFi will be interrupted for ~5 min
• Starpoint 508: Both TN and GPN will be interrupted for ~ 5 min, WiFi will stay up
• Intervention to be scheduled with EN/EL (Patrick Gallay) & IT/FCS (Jose Rendon Molina)
