WP01

A.D’Elia presents

Need to know number of pumping ports.

Spinner would like to give a price for the whole installation. Price could reduce due to test and development at ESRF.

No answer from Radiabeam.  

ACTION: ASK US directly.

ARVA (not good feedback from PSI)

Loads must be splatted in 2 x 25MW loads

Rather heavy components with installation constraints (phase shifter only vertical)

Need to know where to hold the components

ACTION: Could  Ask ALGE to already mark on the mod Hal all the position of items (rf units, holes, etc..) 

Water, electric power, cranes Summer SD?  Needed for SAT

LLRF: we have nothing!

Outsource? Meeting with i-Tech to see what they can provide and at what cost. 

Support the BOC as for modulator 0 on the frame of the modulator. Use crane to install it? 

ACTION: AD’Elia  will speak to Hugo to define pumping ports. 

For phase 0 unrealistic to do in house components. CFT would delay. 

PSI can loan C-band loads and directional couplers. (Long lead time)

For phase 1 could design in house components. 

L.E. : Who is in charge of RF-network drawings?

A.d’Elia: to be discussed.

QQ.  Contact I-Tech  what is the expected cost?

SL: 250 according to discussion during EIC project. Up to Phase 2.

 

WP02

Diagnostics. New layout of diagnostic section. 

 

WP03 

 

WP04 

Hired a young mechanical engineer for the COLD project! Starting in beginning of October. Finishing CEA internship. 

Drawings update soon.

 

WP05 

Discussion during LTSP. Estimation of infrastructure costo for a 140m long linac 6GeV.

Discussion will follow. 

 

WP06

Electrical cubicles: quotation. 

12 cubicles for the moment. 

In the drawings only 8 presently. 

25keuros for 12 cubicles. 

Need 3 quotations. 

RF-cage removal. Quotations in progress. 

Big job. Lead on the roof. 

It is a pity to remove the Faraday cage, but needs to be removed. 

Removing items from linac people. Storing it somewhere, but not easily accessible to RF group. 

Need to find a space for WELDING SPOT set up that has to be moved from Modulator Hall. 

This welding bench is connected to in-house coupler reparation. 

B.Joly will look for a new location for the Welding SPOT.

P.Colomp : plan SPECIFIC meeting for welding workshop and storage. ACTION

In front of RF labs cell 07/08 technical zoom.

 

WP07

No news to share. 

Meeting on network, 2nd September. ACTION send room and change of time to 14.30.

 

WP09

Call to ASNR last week.

Optimistic for authorization in October (only for linac refurbishment)

For COLD authorization waiting for beam dump. 

ACTION: SAFETY meeting. J-L Revol will organize the meeting. 

Also LN2 protection meeting with BIG. Some calculation, but with more detail could finalize. 

Oxigen deficiency meter to be installed. 

 

WP10

No news. 

For Phase 0. We reuse existing magnets. For next phase need finalized specs. 

 

WP11

Presentation by SL

For beam dump, safety to review the proposed setup.

 

Shutdown activities

Possible to install the Crane during USM? Between October and December SD? 

P.Colomp: why not. Need to see together. Possible for sure. Discuss. 

Must see details. Alvaro missing some informations. 

ACTION: Meeting as soon as possible. URGENT. (Participants? BIG, RF, Marc, Isabelle, ALGE, Ope, )

Installation of fluids. 

Crane installation on the passage. Blocking until faraday cage. 

Something could fall on the head of people. 

HR to be discussed 

LLRF person unlikely to be hired. 

RF engineer instead of LLRF person. 

Change profile of position for RF group. 

 

Network:

Ask needs and share 

 

ACTION. SL will send message to collect Network information before meeting on the 2nd September.
