Follow-up of last meeting


The minutes of the previous meeting were approved and are already available in Indico at https://indico.cern.ch/event/365048/.

Kicker removal (Follow-UP)


V. Namora presents the kicker removal status. Since the last meeting, 3 out of the 4 Pulse Forming Line (PFL) drum have been removed. The fourth requires removing electric panels.

D. Parchet will take care of dismantling the kicker platform.

In the B. 393, all the PFL drums are ready and wind-up.

There is an issue with the transmission cables: The purchase has been blocked by the CERN shop. This could delay the cabling tasks by one month. These tasks are parts of the critical path. A meeting will be held the 16th of January to see if the old cables can be re-used.

The demineralised water installation has been planned for mid-April, mid-May. F. Butin asks when the demineralised water will be really needed. Vasco answers that it must be installed one month before the commissioning (mid-April). A. Broche (EN/CV) will check whether this will be possible and give an answer before the end of the month.

Upgrade of the demineralized cooling system for ELENA/GBAR


A. Broche from EN/CV presents the upgrade of the demineralized water cooling system for ELENA/GBAR.

A. Broche presents the new requirements. The Tin (water temperature when injected in the cooling network) depends on the environmental condition, upper limit is around 27 degrees.

C. Carli says that the experiments must be informed of these temperatures.

F. Butin requires that AEGIS experiment should give their input and send back theirs requirements for cooling in the new area (LNE51).

A. Broche shows the piping layout that goes around ELENA and in the building 393. The 3D integration has been completed and approved. The actual milestone is: drawings from 12/01 to 23/01, quotation from 26/01 to 13/02, purchasing from 16/02 to 27/02, materials procurement march 2015, construction from 13/04 to 15/05, testing from 15/05 to 22/05
A. Broche details the actual situation. There is only one cooling tower and one pump. In other words, the system is not redundant. He also adds that currently, the ∆T is only around 4 degrees. It means that the pumps could be slowed down or replaced by pumps with less head. This misconfiguration of the system is power consuming and is also responsible for the high pitch noise present in the AD.

A plan has to be set-up to measure the exact flow in all systems and match this to the real needs.



Installation Planning ELENA


E. Harrouch presents the planning.

The version 3 has been uploaded to EDMS (https://edms.cern.ch/document/1407912/0.3)

Main modifications are:


  • Vacuum installation is now agreed with TE/VSC on the transfer lines (include electrostatic elements and vacuum equipment installation)

  • Injection kicker installation is postponed to November (No impact on the planning but it will be done in coactivity with magnets installation)

  • The magnet installation for the B-Train is now defined (the time dedicated for the installation of the B-Train itself needs to be defined)

E. Harrouch says that the EVM entries that deal with the magnets installation shall be more detailed.

The installation of the transfer lines is foreseen for 2017, the detail planning is currently being set-up and should be ready as a first version for the end of the month.


AOB


F. Butin details the new structure of the IIC meeting for 2015. First half will be for ELENA IIC related matters when second half will deal with the AD ring works during the shutdown.

F. Butin reminds that the civil engineering of the B. 93 is about to start and that the meeting room is going to be moved to the first floor.
